Wastewater treatment device for water and soil pollution treatment and treatment method thereof

Abstract

The invention discloses a wastewater treatment device for water and soil pollution treatment. The device comprises a primary sedimentation tank and a secondary sedimentation tank; the secondary sedimentation tank is fixedly mounted on one side of the primary sedimentation tank; a plurality of sedimentation plates are mounted in the primary sedimentation tank and the secondary sedimentation tank; an aeration tank is fixedly mounted on one side, far away from the primary sedimentation tank, of the secondary sedimentation tank; an aeration assembly is mounted on the aeration tank; a filter tank is fixedly mounted on one side, far away from the secondary sedimentation tank, of the aeration tank; a sludge greening tank is fixedly mounted on one side, far away from the secondary sedimentation tank, of the primary sedimentation tank; a neutralizing tank is fixedly mounted on one side, far away from the aeration tank, of a filtering tank; a liquid inlet is formed in the primary sedimentation tank above the sludge greening tank, and a water outlet is formed in the lower end of one side of the neutralizing tank. Sedimentation, aeration, filtration and neutralization of wastewater are realized, the sludge dehydration cost is reduced, reutilization of wastewater products is realized, the energy-saving and environment-friendly properties are higher, the sedimentation effect is improved through the multi-stage sedimentation treatment, and self-cleaning of sedimentation plates is realized.

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.
