Circulating integrated sewage treatment equipment and use method thereof

Abstract

The invention discloses circulating integrated sewage treatment equipment. The equipment comprises a primary filtration regulation pool, an anaerobic pool, a membrane biological reaction pool, a sludge pool and a reclaimed water pool. One side of the primary filtration regulation pool is equipped with the anaerobic pool, one side of the anaerobic pool is equipped with the membrane biological reaction pool, one side of the membrane biological reaction pool is equipped with the sludge pool, one side of the sludge pool is equipped with the reclaimed water pool, a drainage seat is arranged at the upper part on one side in the primary filtration regulation pool, and a primary filtration plate is installed below the drainage seat inside the primary filtration regulation pool. Sewage in the membrane biological reaction pool completes treatment by a membrane bioreactor, reclaimed water is discharged into the reclaimed water pool, wherein the incompletely treated sewage at the bottom of the membrane biological reaction pool is conveyed to the anaerobic pool again through a second water pump, and after secondary anaerobic treatment, the treated sewage enters the membrane biological reaction pool from a circulation port, thus completing cyclic treatment of sewage, and ensuring the high efficiency of sewage treatment and high discharge standard.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a circulating integrated sewage treatment equipment and a method for using the same. Background technique [0002] Sewage treatment equipment is an industrial equipment that can effectively treat domestic sewage and industrial wastewater in urban areas. It prevents sewage and pollutants from flowing directly into waters, which is of great significance for improving the ecological environment, improving urban quality and promoting economic development. [0003] The patent publication number is (CN 205133348) a kind of sewage treatment equipment, which does not pretreat the sewage to remove impurities that block the pipeline in the sewage; at the same time, it does not perform circular treatment on the sewage to ensure that the sewage is discharged up to the standard. [0004] When the existing sewage treatment equipment treats sewage, it adopts a one-step treatment method, so that ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a kind of circulating type integrated sewage treatment equipment and its use method, in order to overcome the above-mentioned existing sewage treatment equipment when treating sewage, through a one-step treatment method, in the process of sewage treatment, treatment The sewage that does not meet the standard will also be discharged together with the sewage that meets the standard, resulting in waste of resources and environmental pollution; at the same time, sewage often contains large impurities and waste, which need to be treated before sewage treatment, otherwise it is easy to be in the sewage During the treatment process, the pipeline is blocked, causing damage to the equipment and increasing the cost of sewage treatment; the anaerobic bacteria in the anaerobic pool are strict obligate bacteria, and have very strict temperature requirements. There are high temperature anaerobic 50-55 degrees, and medium temperature anaerobic 30- 35 degrees, it will hydrolyze, acidify and methanate the organic matter in the sewage. When removing the organic matter in the wastewater, it is necessary to ensure that the temperature is appropriate, otherwise it will easily cause the death of anaerobic bacteria; at the same time, it is difficult to accumulate sludge at the bottom of the membrane bioreactor only through the mud pump.
