It sets, membrane biological reaction apparatus and PC control devices, the folded plate reaction unit include folded plate reactor and reinforcing reflux, folding
Plate reactor has multigroup folded plate, multigroup folded plate that folded plate reactor is separated into inversion A AO patterns, and inversion A AO patterns are anoxic zone
In preceding anaerobic zone rear, there are intake pump and water inlet, anaerobic zone and the public one block of folded plate of membrane biological reaction apparatus in anoxic zone front end
Make partition wall, the reinforcing reflux includes strengthening reflux line, strengthening refluxing opening and strengthen reflux pump, strengthens refluxing opening peace
In anoxic zone and anaerobic zone, refluxing opening is strengthened in anoxic zone in succession respectively and reflux is strengthened in anaerobic zone at reinforcing reflux line both ends
Mouthful, strengthen reflux pump and be mounted on reinforcing reflux line, and intelligent unidirectionally pumped from anaerobic zone to anoxic zone is flowed, the film biology
Reaction unit includes membrane bioreactor, PH probes, DO probes, aerator and reflux, is had in membrane biological reaction apparatus
Membrane biological reaction apparatus is divided into aerobic zone and diaphragm area by deflector, deflector, and membrane bioreactor is mounted on diaphragm area, film life
Water outlet pump, outlet conduit and pressure gauge, PH probes are inserted into DO probes in aerobic zone object reactor in succession, and aerator gathers
Membrane biological reaction apparatus bottom, reflux can flow back nitrification liquid and sludge simultaneously, and reflux includes refluxing opening, reflux line
With reflux pump, wherein refluxing opening one is mounted in aerobic zone, another refluxing opening is mounted in anoxic zone, and reflux line is in succession
Refluxing opening in refluxing opening and anoxic zone, reflux pump are mounted on reflux line in aerobic zone, the PC control devices can regulate and control into
Water pump, PH probes, DO probes, reflux pump, water outlet pump and pressure gauge.
Compared with the prior art, beneficial effects of the present invention are as follows：
The present invention is combined by carrying out preferred design with PC control devices to folded plate reaction unit, membrane biological reaction apparatus,
At a kind of strengthening biological carbon and phosphorous removal folded plate reactor sewage-treatment plant, with anoxic zone in the posterior inversion in preceding anaerobic zone
AAO patterns, the sewage disposal mechanism for solving AAO have the following problems：1. since anaerobic zone is ranked forefront, the nitrate in returned sludge
Adverse effect will produce to anaerobic zone；2. being located in the middle part of system in anoxic zone, denitrification occupy minus advantage in carbon source distribution,
Thus affect the denitrification effect of system；3. the suction phosphorus power that polyP bacteria is put aside in anaerobic zone is in anoxic section inefficient consumption；4. absolutely
Most of microorganism only undergoes anoxic/aerobic alternate environment and is generally required larger to reach higher denitrogenation dephosphorizing efficiency
Reflux ratio, cause investment and energy consumption it is higher the problems such as.The configuration of the present invention is simple, technological process is simple and direct, operational management is convenient, accounts for
Ground area is small, operating cost is low, stability is high, and nitrogen, phosphorus in removal sewage is suitble to use.
