Industrial wastewater treatment spiral-flow aeration biofilter

Abstract

The invention discloses an industrial wastewater treatment spiral-flow aeration biofilter which structurally comprises an industrial wastewater inlet, an air pipe, a backwash pipeline, a water outletand an automatic treatment tank. The industrial wastewater inlet is mounted at the left end of the automatic treatment tank and fixedly connected together with the automatic treatment tank in an embedded mode, the air pipe is arranged at the left end of the automatic treatment tank, and the backwash pipeline and the air pipe are positioned on the same vertical surface by the automatic treatment tank. According to the industrial wastewater treatment spiral-flow aeration biofilter, by the aid of hydraulic transmission of industrial wastewater, a filtering brake device is started, a filtering rotary disk is durable by the aid of a transmission mechanism and a rotary mechanism, effective filtering can be performed for a long time, rotation of a hydraulic brake device drives a matching mechanism and a mounting rotary mechanism in transmission, oxygen transfer efficiency and effluent quality can be improved, and cost is reduced.

Description

technical field [0001] The invention relates to a swirl aerated biological filter for industrial wastewater treatment, which belongs to the technical field of industrial wastewater treatment. Background technique [0002] Biological aerated filter, referred to as BAF, is a new type of biofilm sewage treatment process developed in Europe and the United States in the late 1980s. It was greatly developed in the early 1990s, with a maximum scale of hundreds of thousands of tons per day. This process has the ability to remove SS , COD, BOD, nitrification, denitrification, phosphorus removal, removal of AOX harmful substances, the aerator is an essential equipment for aeration and oxygenation of water supply and drainage, biological filter, biological treatment composed of gravel or plastic product filler Structures and sewage are in contact with the microbial film growing on the surface of the filler to purify the sewage. [0003] However, this prior art usually uses electric en...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a cyclone aerated biological filter for industrial wastewater treatment, to solve the problem that the prior art usually uses electric energy braking equipment to treat industrial wastewater, which requires a large amount of electric energy , resulting in a large cost, due to the fixed relationship between the filter layer, resulting in poor filtering effect in the later stage, and the fixed aeration port has a low effect on oxygen transmission, which reduces the problem of effluent water quality
