Embodiment Construction

[0026] Hereinafter, the present invention will be further described in conjunction with the embodiments and drawings, which are only for explanation and not intended to limit the protection scope of the present invention.

[0027] The main structure of the bio-immobilized membrane biounit reactor in this embodiment includes a tank body, a biological carrier, a membrane module, high-efficiency bacteria, an aeration device, a tank body, an intercepting net, a protective net, and a pump. The biological carrier is mainly used to load high-efficiency bacteria; the membrane module is mainly used to intercept macromolecular substances and high-efficiency bacteria to ensure the turbidity of the wastewater; the high-efficiency bacteria are specially domesticated and screened, and then pumped to the bio-solid type In the membrane biological unit reactor, and attached to the biological carrier; the aeration device is located at the bottom of the bio-immobilized membrane biological unit re...

Abstract

The invention relates to a biological immobilized type film biological unit reactor. The biological immobilized type film biological unit reactor comprises a pond body and is characterized in that a plurality of film units of a following structure and padding units of a following structure are adjacently arranged in the pond body, and every two adjacent units are separated through a protection net; the side faces of the film unit are formed by the protection nets in a defined mode, and film assemblies are arranged in the film units; the side faces of the padding units are formed by the protection nets in a defined mode, interception nets are arranged on the bottoms of the padding units, and each padding unit is filled with a plurality of biological carriers. According to the biological immobilized type film biological unit reactor, 30-40% of floor space can be saved, no sludge settling problems occur, MLSS concentration in the reaction pond can reach 10,000 mg / L or above, and the load impact resisting capacity is high. The removal rate of the biological immobilized type film biological unit reactor on a main pollutant COD is larger than or equal to 93%, and the removal rate on a main pollutant SS is equal to 100%.

Description

[technical field] [0001] The invention relates to aerobic process equipment in sewage treatment equipment, in particular to a biologically immobilized membrane biological unit reactor. [Background technique] [0002] Domestic industrialization and urbanization have brought more and more attention to water treatment environmental issues and have affected human daily life. my country's urban sewage has the characteristics of large water production, wide coverage, various types, and difficult treatment. Traditional water treatment equipment has many disadvantages in terms of investment cost, energy consumption, floor area, treatment effect, etc. Newer water treatment equipment. With the emergence of new environmental protection equipment, urban sewage treatment is in a golden period of reform. Upgrading of Urban Sewage Treatment During the period from the "Tenth Five-Year Plan" to the "Twelfth Five-Year Plan", my country's urban sewage treatment market has experienced rapid d...
