[Technical name] High salinity organic industrial wastewater treatment and resource recovery technology
[Technical content] Based on salt-resistant special adsorption materials, the removal of water-soluble refractory pollutants in high-salt organic industrial wastewater and resource recovery are realized.
[Scope of application] Toxic organic industrial wastewater with high salt content (> 3%), difficult to biodegrade
[Technical development stage] Engineering demonstration
This technology is based on a new type of adsorption material that has high salt tolerance, high adsorption capacity and high selectivity for water-soluble organic pollutants, and realizes water-soluble and difficult-to-degrade organic pollutants (such as phthalic acid) in high-salt organic wastewater. ) Adsorption and separation; After the resin is saturated with adsorption, it is desorbed with alkali to achieve resource reuse of useful substances.
The whole process is realized through the development of a complete set of integrated devices with a new type of continuous adsorption and regeneration equipment as the core, which has the characteristics of low cost, high degree of automation, and simple operation.
The process is "water quality adjustment-mechanical filtration and removal-phthalic acid separation and recovery-biochemical treatment". details as follows:
1. First adjust the pH of the high-salt organic wastewater to a suitable range, and adjust the form of organic matter in the wastewater;
2. Mechanical filtration, using precision filters to remove solid substances that affect resin adsorption in wastewater;
3, resin adsorption: continuous regeneration resin adsorption integrated treatment separation and recovery of phthalic acid and other organic matter in high-salt wastewater;
4. Biochemical treatment: The wastewater after recovering organic matter is subjected to HBR high-efficiency biological treatment, and finally the wastewater discharge is achieved.
1.Salt-resistant special adsorption materials;
2.High-concentration, high-salt, refractory organic industrial wastewater treatment and resource integration process centered on resin adsorption technology;
3. New continuous adsorption and regeneration water treatment device.
