Building construction process domestic sewage treatment ground filtering device and filtering method

Abstract

The invention relates to a building construction process domestic sewage treatment ground filtering device and a filtering method. The device comprises a filtering pipe, a water inlet pipe is arranged at one end of the filtering pipe, a water outlet pipe is arranged at the other end of the filtering pipe, and four filtering layers are arranged in the filtering pipe and are sequentially gravel, ceramsite, fine sand and sponge from one end of the water inlet pipe to one end of the water outlet pipe. Domestic sewage primarily treated by a septic tank is secondarily filtered by the four filtering layers including the gravel, the ceramsite, the fine sand and the sponge, water quality is further improved to meet secondary pollution exhaust criteria, and produced sewage in the whole engineering construction period is controlled, so that surrounding environments are protected.

Description

Technical field [0001] The invention relates to a domestic sewage treatment technology, in particular to a ground filtering device and a filtering method for domestic sewage treatment during construction. Background technique [0002] Judging from the current situation, during the construction process of the construction project, most of the local municipal sewage and rainwater systems are imperfect. In addition, the construction unit and the construction unit pay little attention to it, resulting in a large amount of construction wastewater, Environmental pollution sources such as sewage directly damage the local surface water quality and ecological environment. [0003] In view of the above situation: the existing sewage treatment in the construction process generally adopts the septic tank precipitation fermentation technology. Use the sedimentation chamber and the corruption chamber inside the septic tank to remove the suspended organic matter in the domestic sewage. [0004] T...

AI Technical Summary

Problems solved by technology

[0005] Deficiencies: ① Septic tanks are primary transitional living treatment structures

[0006] ② Sewage treatment is not complete, only 50%~60% of suspended solids are removed
