Integrated apparatus for restoring ecology of rivers

Abstract

The invention relates to the field of town river pollution treatment, and concretely relates to an apparatus directly placed in water to be treated and used for restoring the ecology of rivers. The apparatus is formed by one or more biochemical treatment segments, a sludge-water separation segment, a sludge digestion segment and an apparatus energy supply segment, and an oxygen supply device and a suspension filler are arranged in the treatment monomer of the biochemical treatment segment. Sludge undergoing a multi-stage biochemical decomposition process enters the sludge-water separation segment, sludge-water separation removal is carried out according to the settlement characteristics, the obtained supernatant is collected by a water outlet weir, the collected supernatant automatically flows to natural water to complete the whole removal process, precipitated sludge is lifted and returned to the front biochemical treatment segment in order to supplement the quantity of microorganisms in the biochemical treatment stage and alleviate the loss of the sludge in the biochemical treatment stages. The apparatus truly alleviates the river pollution degree, runs for 4 weeks to effectively improve the quality of water in the town rivers, and provides a new thinking for treatment of polluted rivers in the land-short and inhabitation population-dense segments.

Description

technical field [0001] The invention relates to the field of pollution treatment of urban rivers in the field of environmental protection, in particular to the treatment of polluted rivers and natural water bodies surrounded by direct discharge of domestic sewage. Background technique [0002] Due to the development of today's cities, although we have a series of means to treat urban sewage, in the development of cities and towns, there are still a large area of ​​natural water bodies in the old urban areas that are seriously polluted, and the residential areas around the natural rivers in the old urban areas are due to imperfect pipeline network , and the original living habits of local residents, most of the sewage generated by living in residential areas along the street is directly discharged into the river, resulting in serious river pollution in the old urban blocks. While improving this situation, we also encountered the difficulty and high cost of laying new rainwate...

Problems solved by technology

[0002] Due to the development of today's cities, although we have a series of means to treat urban sewage, in the development of cities and towns, there are still a large area of ​​natural water bodies in the old urban areas that are seriously polluted, and the residential areas around the natural rivers in the old urban areas are due to imperfect pipeline network , and the original living habits of local residents, most of the sewage generated by living in residential areas along the street is directly discharged into the river, resulting in serious river pollution in the old urban blocks

While improving this situation, we also encountered the difficulty and high cost of laying new rainwater and sewage pipes into the urban sewage main network; and it will affect the daily life of surrounding residents, the problem of communication with the surrounding elderly residents and the development of this project Difficulties in working progress and other problems
