Floor-type biochemical combination pond

Abstract

The invention relates to a floor-type biochemical combination pond. The pond comprises first-layer biochemical pond bodies, a second-layer biochemical pond body and a third-layer biochemical pond body. The first-layer biochemical pond bodies include the hydrolysis acidification pond bodies and the sludge pond body, the sludge pond body is located at the left edges of the hydrolysis acidification pond bodies, and a running water notch is formed in the portion, three quarters away from the pond bottom, of the right side edge of the sludge pond body and communicated with the hydrolysis acidification pond bodies; one or more hydrolysis acidification pond bodies are arranged, and a sewage inlet is formed in the top of each hydrolysis acidification pond body. The second-layer biochemical pond body includes one or more aerobiotic biochemical pond bodies, and water outlets and water inlets are formed in the pond tops of the aerobiotic biochemical pond bodies and the pond bottoms of the first-layer hydrolysis acidification pond bodies respectively. The floor-type biochemical combination pond has the advantages that the land space is saved, and by using a simple floor chamber structure, resource waste is avoided.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a floor-type chemical-biological combination pool. Background technique [0002] Due to the increasing shortage of land resources, especially the extremely limited available land for established factories, the land reserved for sewage treatment projects is often the most scarce when factories are expanded. However, the country's "three simultaneous" policy stipulates that environmental protection facilities are essential . Due to the requirements of its process, the sewage treatment project has certain requirements for the volume of the pool. It occupies a lot of land and uses a lot of facilities. The use of more facilities is relatively more expensive for electricity and water, so the sewage treatment is very wasteful. various resources. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide an env...
