Waste water treatment device and treatment method for water and soil pollution control

Abstract

The invention discloses a waste water treatment device for water and soil pollution control, comprising a primary sedimentation tank and a secondary sedimentation tank, a secondary sedimentation tank is fixedly installed on one side of the primary sedimentation tank, and A number of sedimentation plates are installed inside. The side of the secondary sedimentation tank away from the primary sedimentation tank is fixed with an aeration tank. The aeration tank is equipped with an aeration component. The filter tank, the side of the primary sedimentation tank away from the secondary sedimentation tank is fixedly installed with a sludge greening tank, the side of the filter tank away from the aeration tank is fixedly installed with a neutralization tank, and the primary sedimentation tank above the sludge greening tank is equipped with an inlet Liquid port, the lower end of one side of the neutralization tank is equipped with a water outlet, which realizes wastewater sedimentation, aeration, filtration and neutralization treatment, reduces the cost of sludge dehydration, realizes the reuse of wastewater products, is more energy-saving and environmentally friendly, and multi-stage sedimentation The treatment improves the sedimentation effect and realizes the self-cleaning of the sedimentation plate.

Description

Technical field: [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a wastewater treatment device for water and soil pollution control and a treatment method thereof. Background technique: [0002] Wastewater refers to the general term for the water discharged during residents' activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other useless water such as primary rainwater that flows into drainage pipes and channels. Wastewater treatment is to use physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, and achieve wastewater recycling and reuse, making full use of water resources. [0003] At present, when the wastewater treatment device is used for the treatment of wastewater containing a large amount of sediment, the sedimentation effect is poor, it is difficult to meet the needs of wastewater sedimentation, and a large amount of sediment...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of wastewater treatment device and its treatment method for water and soil pollution control in order to solve the above problems, which solves the problem that the current wastewater treatment device has poor sedimentation effect when it is used for the treatment of wastewater containing a large amount of sediment, and it is difficult to meet the requirements. The demand for wastewater sedimentation, and a large amount of sedimentation sludge products are produced, which increases the energy consumption and cost of wastewater treatment sludge dehydration.
