(2) Folding plate / partition flocculation zone
The structure of the folding plate flocculation tank is to place a certain number of parallel folding plates or corrugated plates in the pond.
http://euhowblog.com/jsclgc/scshscl/jhsjh/ 纵向分散地输入微量而足够的能量，有效地提高输入能量利用率和混凝设备容积利用率，增加液流相对运动，以缩短絮凝时间，提高絮凝体沉降-眭能。 Mainly uses the Coanda turbulent energy consumption caused by the separation of the boundary layer caused by the scaling or turning of the folded plate, and maintains the horizontal uniformity along the course in the flocculation tank, http://euhowblog.com/jsclgc/scshscl/jhsjh/longitudinal Dispersely input a small amount of sufficient energy, effectively improve the input energy utilization rate and the coagulation equipment volume utilization rate, and increase the relative movement of the liquid flow, so as to shorten the flocculation time and improve the flocculation settling-energy.
The mathematical description of flocculation is generally divided into two independent processes: migration and adhesion. The migration process creates collisions of particles. Migration is caused by differences in the speed of particles in the water.
In the folding plate flocculation tank, the speed difference is considered to be caused by the following three factors:
(1) Brownian motion of particles (plays a major role in anisotropic flocculation);
(2) Turbulent vortex (co-flocculation);
(3) Difference in sedimentation speed between particles (differential flocculation).
Adhesion depends on transient forces related to the surface properties of the particles themselves.
The influence of the hydraulic characteristics of the folding plate unit on the collision of floc particles is mainly as follows: the vortexing of the folding plate unit and the continuous and uniform unit setting improve the distribution of turbulent energy consumption, thereby increasing the value of the flocculation method, and therefore the Flocculation effect. Water flows through the folding plate unit, and under the action of the gradually expanding section and the shrinking section, a symmetrical vortex and a unilateral vortex can be formed. The separation of the boundary layer of the current at the wave crest is the cause of the vortex. According to the diffusibility of the vortex, it will be further decomposed into small-scale vortices until the Reynolds number associated with the water current micelles is low enough to no longer produce smaller vortices. http://euhowblog.com/jsclgc/scshscl/jhsjh/ 一直到微尺度的涡旋。 At the same time, the large-scale vortex draws kinetic energy from the mainstream and is transferred to the smaller-scale vortex during the movement, so that it is transmitted step by step, http://euhowblog.com/jsclgc/scshscl/jhsjh/ all the way to the micro-scale Vortex. In larger-scale vortex motion, fluid viscosity has almost no effect and can be ignored, so there is almost no energy consumption in kinetic energy transfer. In micro-scale vortex motion, fluid viscosity will play a major role, which is transmitted to these The energy of the low-level vortex of Z is converted into thermal energy through viscous effect. There are countless large and small vortices in the water flow at the same time, which produces a series of pulsating frequencies with a continuous frequency spectrum.
The grid flocculation tank is formed by a series of vertical shafts. The flocculation tank is divided into many equal squares. The flow of incoming water flows from one grid to the next, and flows up and down until it exits. In two-thirds of the whole pond, a grid or grid is placed horizontally. When the water flows through the gap of the grid or grid, the water shrinks and expands after passing through the mesh to form a good flocculation condition.
(3) Sloping tube sedimentation area
The P series inclined tube sedimentation area is in principle equivalent to the H series inclined tube sedimentation, except that it is a single layer inclined tube and the H series is a double layer inclined tube.
According to the sedimentation principle of the advection sedimentation tank to remove dispersed particles, the precipitation efficiency of a tank is proportional to the plane area of the tank under the conditions of a certain flow rate and a certain particle sedimentation speed. For this reason, if in the same pond, it is divided into N intervals according to the height, so that the horizontal area is increased by N times, in theory, the precipitation ability can be increased by N times. After the pond is divided into many horizontal shallow grids, although the sedimentation efficiency can be improved, it is difficult to remove mud. To this end, the horizontal plate is changed to a sloping plate. On the one hand, the horizontal projection area is increased, and one area of mud can automatically fall to the bottom of the pool for easy removal .
After adding many parallel inclined plates, the wet perimeter of the water cross section of the pool is increased, and the hydraulic radius is reduced. For this reason, at the same horizontal flow velocity v, the Reynolds number Re can be greatly reduced, thereby reducing water turbulence and promoting precipitation.
Adding a sloping plate shortens the particle precipitation distance and reduces the precipitation time. The inclined plate and inclined tube sedimentation tank has achieved good results in production practice, especially the removal effect of dispersive particles is more significant.
(4) Mud collection area and mud discharge
The incoming water slowly enters the flocculation zone, undergoes a thorough coagulation reaction, and then enters the inclined pipe sedimentation zone. Under the action of gravity, the deposited sludge slides down the inclined direction of the inclined pipe, and at the same time, the alum flower that slides down in the diversion inclined pipe. Under the action of hydraulic power, it is pushed into the sludge hopper of the water purification device.
The device is provided with a cone mud bucket to collect the mud, which can make the sludge get full contact, gather and compress, and is beneficial to the complete dredging. The dredging area adopts gravity dredging, and the dredging valve opens automatically at regular intervals, and flows out through the dredging pipe under the gravity of the water itself. The mud bucket gravity discharges the mud automatically, which is fully controlled and saves water.
(5) Quick filter
The filter area adopts the traditional quick filter pool arrangement form, and Z is used as an extensive water filtration facility to remove the residual suspended matter in the water after coagulation and sedimentation treatment. The turbidity of the effluent of the fast filter can reach below 3NTU. The filter material is generally a single layer of fine sand graded filter material. The flushing is performed by single water. The flushing water is supplied by a backwash pump.
， Z后经由配水干管、清水支管及干管后进入清水池。 During filtering, the valve of the branch pipe of the filter is opened, and the raw water passes through the filter material layer and the support layer from the top to the bottom, and is collected by the branch pipe of the water distribution system. After Z, it enters the clear water tank through the distribution pipe, the branch pipe and the main pipe. When the effluent water quality does not meet the requirements or the head loss of the filter layer reaches a large value of Z, the filter material needs to be backwashed. http://euhowblog.com/jsclgc/scshscl/jhsjh/ 均匀分布在滤池平面，冲洗废水流入排水槽、浑水渠排走。 In order to make the filter material layer in a suspended state, the backwash water passes through the filter material layer from the bottom to the top of the water distribution system. Http://euhowblog.com/jsclgc/scshscl/jhsjh/ is evenly distributed on the filter surface The washing wastewater flows into the drainage tank and muddy water channel and is discharged.
During backwashing, after the sewage has been filtered for a certain period of time, the resistance of the filter layer gradually increases. When the water level rises to a certain level, the automatic backwashing valve and backwashing pump are opened to form backwashing. The backwash lasted 4-5 minutes, and the backwash sewage was discharged into the sewage tank, and was led by the sewage pipe into the sewer or mud pit.

Although compared with the P series, it has certain defects, but it still has water purification. Good effect, wide range, energy saving, small footprint and low water consumption.
The water purification device itself has a series of operating procedures from reaction, flocculation sedimentation, water collection, water distribution, filtration, backwashing, and sludge removal. All of them have achieved the effect of fully automatic operation. The PLC interface can be reserved in the central control cabinet. In addition to regular water quality monitoring, there is no need to operate and manage the water purification device.
The folded plate / grid flocculation layer can make the impurity particles in the raw water get sufficient collision contact therebetween, and the probability of adsorption is increased, so it can adapt to the water temperature and turbidity of various raw water, and the impurity particle removal rate is high.
The rapid sludge concentration chamber and adjustable automatic sludge drainage system can ensure the timely removal of excess sludge, thereby ensuring a stable removal rate of foreign particles.
The design of folded plate flocculation and inclined plate sedimentation greatly improves the flocculation and sedimentation effect, so that the quality of the precipitated water can always be maintained in good condition.
Efficient flocculation and sedimentation effect keep the quality of the sediment effluent water in good condition.
