Principle of work: this new bio filter tank be mainly used to process domestic sewage in rural areas, operational mode adopt periodic running, sequence batch (process, a cycle of operation is 12 hours, new bio filter tank can according to sewage disposal scale list group, organize paired running more.
1, sewage enters the aeration mixing zone of pond body in batches, by the oxygenation bottom aeration mixing zone and return-flow system, the side plate water distributing pore re-used on aerator tank side plate is connected with biofiltration district, under the effect in two special tectonic regions, sewage aerobic, anoxic constantly circulate, nitrification and denitrification synchronously carries out, the biological flora that on the biologic packing material in simultaneously biofiltration district, enrichment is abundant, give up Organic substance in water, nitrogen and phosphorus in effective place to go;
2, after oxygenation and return-flow system stop, then the outlet valve in Graceful pool is opened, the effluent trough side plate in Graceful pool arranges side plate water distributing pore, sewage flows into Graceful pool bottom biofiltration district, activated sludge floc in effective intercepting sewage and the SS in sewage, qualified discharge after water outlet.
3, arrange spoil disposal emptying sludge pipe and Pai Kou in aeration mixing zone and biofiltration district, after one-period completes, discharge mud and emptying are once, and the sludge sump that mud flows into sewage works stores.
The utility model has the advantages that:
It is nervous that the utility model is applicable to not only land used, and the area requiring effluent quality strict.On the body structure of pond, form is compact, saves land area, and adopts periodic running and sequence batch (tupe to be conducive to the discharge of process country sewage irregularities, water quality unstable.
