    Catering sewage treatment equipment

    Restaurant wastewater treatment equipment

    Equipment introduction:
    The wastewater from the restaurant sewage treatment equipment is complex in composition and high in organic matter. It mainly includes dietary fiber, starch, fats of animal and vegetable fats, various condiments, detergents and proteins. Most of them contain fats and vegetable oils. The oil floating on the water surface affects the oxygen exchange at the air-water interface. The oil dispersed in water can be oxidized and decomposed by microorganisms. Therefore, oils not only reduce the rate of reoxygenation, but also consume dissolved oxygen in the water. Make water quality worse. Pollutants in catering wastewater mainly exist in the form of colloids, with low pH value, high ss value, high turbidity, and relatively high BOD and COD values. Generally speaking, there are many organic components in the catering sewage, and the combined effects of the components are strong and the stability is poor, but the toxicity is not large and the pretreatment is relatively difficult. The discharge time has a certain regularity, the instantaneous discharge flow is large, noon and evening It is usually during the peak period of kitchen sewage discharge.
    。 On the basis of summing up the operating experience of domestic and foreign restaurant sewage treatment equipment, combined with its own scientific research results and engineering practice, the company has designed a set of underground organic sewage treatment equipment that can be buried. Its equipment is advanced in the late 1990s at home and abroad. Process and manufacturing technology, producing ZL-ctws001 (1-50m3) series of sewage treatment equipment with carbon steel anticorrosion and stainless steel as main raw materials. The main purpose is to make the catering sewage and similar industrial organic sewage reach the discharge standard required by users after being treated by the equipment.

    Equipment technology:
    The directly recovered restaurant sewage is mechanically removed to remove large impurities such as bones, vegetables, and even cleaning cloths in the water, as well as impurities such as starch, protein, sugars, detergents and colloidal substances. The liquid portion is then subjected to oil-water separation. For acid precipitation and water washing of the oil-containing part, waste oil is obtained, and the amount of acid added in the acid precipitation process to control the pH value between 2-3 is preferably Z. After the oil-water separation water part is mixed with water washing water, the water quality and water volume are adjusted through the adjustment tank, and then lifted to the coagulation air flotation tank by a pump to remove most of the SS, oil and some organic matter, and then biochemical treatment. The biochemical treatment adopts the SBR-PACT method. Powdered activated carbon is added to the biochemical tank, and the effluent of the biochemical treatment reaches the standard discharge. The sludge enters the sludge concentration tank for dehydration treatment. In this process, the treatment of catering wastewater is composed of a pretreatment system and a biochemical treatment system. The conditioning tank and the coagulation air flotation tank mainly stabilize water quality and remove or reduce organic and inorganic substances in the wastewater that affect subsequent biochemical treatment . Because the pH value of the sewage influent water is low, it is acidic sewage, and the oil content is high. Here, a coagulation air flotation method is used to neutralize the alkali.
    Process advantages:
    1. The equipment is buried under the ground, and it can be greened on it, and the environment is beautiful.
    2. The entire equipment generally does not require special management.
    3. It can reduce the floor space, and a parking lot can be built above the equipment without the need to build a factory building and other facilities.
