Biological ecological purification method for surface water

Abstract

The invention relates to a biological ecological purification method for surface water. The technical key points are as follows: the method comprises a resident sewage treatment system and a rain sewage treatment system; the residential sewage treatment system comprises a house main body; a water inlet pipe, a first drain pipe and a second drain pipe are arranged in the house body; discharged sewage is discharged into a high-pressure pump pumping and spraying pool through the first drain pipe, the discharged sewage is discharged into a septic tank through the second drain pipe, septic tank water is pumped into the high-pressure pump pumping and spraying pool through a first water pump to be blended into Baume degree mixed liquid, and then the Baume degree mixed liquid is pumped and sprayedto the ground through a high-pressure pump; according to the rainwater and sewage treatment system, after rainwater flows toward a ditch and a river branch, the ditch and the river branch are dividedinto a plurality of water storage areas, a water storage dam is arranged between every two adjacent water storage areas, the water surface of each water storage area is divided into an aquatic vegetation growth area and a water flow area in the width direction, and a sewage blocking floating mat net is arranged between each aquatic vegetation growth area and the corresponding water flow area. A pollution source is thoroughly cut off, and rainwater and sewage are subjected to split-flow purification treatment.

Description

【Technical field】 [0001] The present invention relates to a purification method for naturally purifying surface water through biological ecology. 【Background technique】 [0002] Surface water sewage generally includes domestic sewage and rainwater treatment of residents. Now every household and all living quarters lead domestic sewage to ditches and rivers outside the house, and urban domestic sewage is also directly discharged to the river, which is likely to cause the water body of the river to be black and smelly. [0003] At present, the more common method in the market is sewage interception and diversion. Its essence is to speed up the flow of sewage from a certain place to the downstream, and continuously extend and expand the polluted area without reducing the nutrient-rich substances in the water at all. Others are treated by sewage treatment plants, and the sewage is introduced into the pipeline to the sewage treatment plant. In the sewage treatment plant, it is p...

AI Technical Summary

Problems solved by technology

Others are treated by sewage treatment plants, and the sewage is introduced into the pipeline to the sewage treatment plant. In the sewage treatment plant, it is purified by sedimentation or adding certain drugs. However, the water flowing out after being treated by the sewage treatment plant still contains a large amount of ammonia and nitrogen. , phosphorus and other nutrient-rich substances, did not achieve the purification effect
