Sewage treatment system and sewage treatment method thereof

Abstract

The invention relates to a sewage treatment system and a sewage treatment method thereof. The sewage treatment system comprises an adjusting tank, a sludge tank, reaction integral equipment and assistant integral equipment, wherein the reaction integral equipment consists of a BBE (Biomedical Biological Engineering) biological efficient treatment tank, a secondary sedimentation tank, a coagulation-flocculation reaction tank and a third sedimentation tank; the assistant integral equipment consists of a dosing room, a warehouse, an air blower machine room and a control room; a plurality of aeration hoses are arranged in the BBE biological efficient treatment tank; the aeration hoses are connected with air inlet tubes and air blowers; efficient active suspended packing for culturing facultative anaerobe is arranged in the BBE biological efficient treatment tank; air blowers are arranged in the air blower machine room; a main control mechanism is arranged inside the control room; and the dosing room is connected with the adjusting tank, the secondary sedimentation tank, the third sedimentation tank and the coagulation-flocculation reaction tank through dosing pipelines respectively. By adopting the sewage treatment system, nitration and denitrification can be synchronized, meanwhile sludge treatment can be achieved rapidly, the whole process is high in integration degree, automatic control is achieved, and a remarkable water quality improvement effect is achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment system and a sewage treatment method thereof. Background technique [0002] With the rapid development of my country's social economy, the problem of water environment pollution is becoming more and more serious. All kinds of sewage and slightly polluted water can be seen everywhere, which seriously threatens the water environment. Especially in recent years, my country's catering industry and construction industry have developed too fast, and a large amount of domestic sewage and feces are discharged into rivers. Domestic sewage contains a large amount of organic matter and pathogenic bacteria. Under the action of bacteria, it is easy to produce foul-smelling substances. [0003] Patent application number 201710210370.1 discloses a decentralized sewage treatment method. The method is to introduce sewage into the bottom of the pool. Sewage from the fi...
