Embodiment 1

[0025] The mode of operation of the present invention is as follows: as figure 1 As shown, the sewage first enters the water distributor 2 at the bottom of the anaerobic tank 15 through the peristaltic pump 1 to distribute water for anaerobic biological treatment. The treated water is pumped out from the membrane module 3 by the peristaltic pump 4, and then discharged through the flow valve 5 for subsequent treatment. Biogas produced during anaerobic treatment (CH 4 , CO 2 mixed gas), collected by the biogas collection pipe 6 at the top of the reactor, and enters the biogas collection device 7, part of the biogas is pumped out by the peristaltic pump 8 to the aeration pipe 9 at the bottom of the anaerobic tank for aeration, and the gas returns to the anaerobic tank after aeration. Above the oxygen tank, a biogas cycle is formed. The intelligent dynamic anti-pollution module is located above the anaerobic tank, and is fixed with the reactor through the module fixing device 1...

Abstract

The invention relates to a novel intelligent dynamic anti-pollution anaerobic membrane bioreactor, and belongs to the technical field of anaerobic membrane bioreactors. The novel intelligent dynamic anti-pollution anaerobic membrane bioreactor is characterized in that a membrane assembly is located in an intelligent dynamic anti-pollution module, the module is composed of an outer frame, an intelligent composite carrier of a biological membrane inhibitor D-amino acid, a D-amino acid concentration monitoring system and a carrier replacement system, the upper end of the module is fixed with a reactor through a fixing device, a reactor water inlet is positioned at the bottom of an anaerobic tank, a water outlet is internally connected with the membrane assembly, a biogas collecting pipe is connected to a biogas collecting device through a gas pipe, and an aeration device is positioned at the bottom of the reactor. According to the invention, D-amino acid is released through the intelligent dynamic anti-pollution module to inhibit membrane biological pollution, after the D-amino acid is released, a new composite carrier can be rapidly replaced and supplemented so as to regenerate the biological pollution resistance of the module, and the aeration effect and the hydrodynamic property in the reactor can be improved through the module so as to improve the anti-pollution effect, so that continuous control of membrane biological pollution is realized, and the system operation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to the technical field of anaerobic membrane bioreactors, in particular to a novel intelligent dynamic anti-pollution anaerobic membrane bioreactor. Background technique [0002] Anaerobic membrane bioreactor is a new type of wastewater biological treatment technology that couples membrane separation technology and anaerobic biological technology. It fully combines the advantages of the two technologies and realizes the effective separation of sludge retention time and hydraulic retention time. On the basis of the effluent water quality requirements, the energy consumption demand of the system operation is further reduced, the sludge production is reduced, and the recovery of bioenergy methane is realized. Therefore, it is widely used in the treatment of urban domestic sewage, industrial wastewater and rural livestock and poultry breeding wastewater. Today, when "sustainab...
