Dishwashing wastewater treatment technology

Time: 2019-12-02

           Dishwashing wastewater contains a lot of pollutants. Meanwhile, dishwashing wastewater and disinfectant and caustic soda are added to dishwashing wastewater. The pH value is higher, and directly discharged into rivers or surface water will seriously pollute the water and soil environment, destroy the original function of the water body, endanger human health and produce agricultural and fishery products, such as eutrophication and decomposition of pollutants, and compete with aquatic animals for oxygen. Water quality causes fatal injury. On the other hand, fresh water as a resource related to the national economy and the people's livelihood has increasingly mentioned a strategic height. Therefore, the comprehensive improvement of dishwashing wastewater is a forward-looking strategic decision for sustainable development, and will contribute greatly to protecting water environment, reducing pollution and maintaining ecological balance.

Wastewater treatment technology:
The waste water is designed before the regulating pool, and the majority of scum and insoluble substances are removed. The sewage in the regulating tank is put into the flotation machine through the submersible sewage pump. The effluent of the flotation machine enters the anoxic pond. The main function of the anoxic pond is to carry out denitrification and reduce the ammonia nitrogen value in the water. Then the polluted water enters the contact oxidation pond, decomposes most of the COD and BOD in the water, and nitrates, and enters. In the next treatment section, the water in the aerobic tank is settled through the two sedimentation tank, and the final water will come into the clear water tank. The water in the clear pond can be discharged by standard through disinfection.
It is recommended that equipment be used: Li De research and development Integrated sewage treatment equipment
