Sewage remediation treatment method

Abstract

The invention discloses a sewage remediation treatment method. A system used in the method comprises river banks on two sides of a riverway, an oil-water separation device, an aquatic plant remediation device and a microbial remediation device, wherein a domestic sewage discharge channel is arranged on the river banks; the oil-water separation device is arranged at the outlet end of the domestic sewage discharge channel; and the oil-water separation device comprises a buffer pool, a partition plate is arranged in the buffer pool and divides the buffer pool into an oil separation cavity and a water drainage cavity, a gap is reserved between the partition plate and the bottom of the buffer pool, the oil separation cavity directly communicates with the domestic sewage drainage channel, a sewage drainage port is formed in the outer wall of the water drainage cavity, and the sewage drainage port is lower than the top edge of the partition plate. The system is reasonable in arrangement and design, the pollution of semi-closed river and lake water bodies can be effectively eliminated, water quality improvement effect is ideal, and pollution load of incoming water is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of river course restoration, in particular to a method for restoration and treatment of sewage. Background technique [0002] With the development of cities, some natural river water bodies have been seriously polluted, and surface river water bodies are receiving more and more pollution loads. The water quality of rivers is generally in the national surface water quality standard V class or even inferior V class. In some seriously polluted rivers, due to the high concentration of nutrients such as nitrogen and phosphorus, black and odorous phenomena appear in the rivers, and the self-purification capacity of the rivers is not enough, which has caused a great impact on the ecological environment. River water purification and management is the focus of people's attention, and it is also a very important problem that needs to be solved urgently. [0003] How to reduce the pollution load of a large amount of i...
