Description

A kind of bio-denitrifying sewage dephosphorization apparatus

Technical field

The utility model is related to dirty water living creature processing technique, specially a kind of integrated bio-denitrifying sewage dephosphorization dress It puts.

Background technology

Sewage Biological Treatment, which refers to, is removed the pollutants such as organic matter, nitrogen, phosphorus, the SS in sewage using the metabolism of microorganism It removes, makes to purify the sewage.The necessary condition for realizing bio-denitrifying sewage dephosphorization is to create anaerobism, anoxic and aerobic environment.

Publication No. CN104150589A, application number 201410421119.6 document disclosed in a kind of " integration is without ladder Spend activated sludge sewage-treatment plant ", structure includes the housing for vertical cylinder, and it is vertical to be equipped with outer layer in the housing cavity Cylinder and the vertical cylinder of internal layer, the vertical cylinder of outer layer (i.e. so-called " three phase separator ") are and described positioned at housing cavity top Cyclic annular mud-water separating area is formed between housing wall, cyclic annular mud-water separating area top is equipped with discharge outlet；The vertical cylinder of internal layer is (i.e. So-called " enhancing tube ") inner cavity for flow rising passway, the chamber on the outside of the vertical barrel wall of internal layer is flow to lower channel, interior The upper and lower nozzle of the vertical cylinder of layer communicates respectively with the flow to the upper and lower part of lower channel, and forms the water in the housing Flow circulation canal；Under cyclic annular mud-water separating area between the vertical cylinder of the outer layer and housing wall and the flow are into lower channel Portion communicates；Setting wastewater inlet in the middle part of the vertical walls of the housing, the middle and lower part of housing vertical walls are set (i.e. below wastewater inlet) Put sludge outlet, the lower end setting air diffuser of the vertical cylinder lumen of internal layer, by being aerated pipeline and being located at outside housing The air pump connection in portion.The processing unit is discharged using the air that air pump provides by diffuser, to sewage oxygenation and shape Make water circulation channel internal circulation flow of the sewage in housing into effect is promoted, realize sewage purification.Its deficiency is：1) due to Air diffuser is located at the lower end of vertical internal layer cylinder inner cavity, and water inlet and sludge outlet are in the vertical walls of housing (top of housing lower cone section), first, downward with the flow circular passage of water inlet and sludge outlet communicates, in operation, institute The sewage of entrance and flowing water stream is in the region and dynamically mixes shape into lower channel i.e. with flow by the sludge of discharge State, i.e., without apparent high concentration sludge accumulation regions, the pollutant in sewage is difficult to obtain the suction-operated and suction of high concentration sludge Attached effect；Second, the sludge concentration of sludge outlet discharge is low, it is unfavorable for the processing of follow-up sludge；Third, water inlet and sludge go out Mouthful be set in the vertical walls of housing central section and middle and lower part, housing cavity bottom section there are sludgd deposition and hardened phenomenon, and In the component for overhauling housing and inner cavity, it is impossible to be directly vented the mud mixture of housing cavity lower part by outlet, no Convenient for the maintenance and repair of equipment.2) it is carried since the device is single using the air that air pump provides as to sewage oxygenation and flow It rises and the power that is flowed in circulation canal, there is the contradiction for promoting power and oxygenation capacity, when with influent quality, water Change, when dissolved oxygen concentration is excessively high in housing, it is desirable to reduce air capacity, and reducing air capacity can cause to promote power reduction, carry Liter power reduces the muddy water mixed effect in the rate of circulating flow and mixed liquor that will influence sewage, so as to influence treatment effect, works as shell When internal dissolved oxygen concentration is too low, air capacity need to be increased, air capacity can cause to promote power increase when increasing, promote power and increase When big muddy water mixing intensity can enhance, and excessive muddy water mixing intensity can restrict the formation of active pollution index, in device Each region of water circulation channel is difficult to generate the concentration difference of dissolved oxygen, it is difficult to formed in the device it is apparent, when having certain flow through Between anaerobism, anoxic and aerobic alternate environment, so as to influence Nitrogen/Phosphorus Removal, thus be unfavorable for operation process stablize fortune Row.In addition, the entrance in cyclic annular mud-water separating area lower end, the upper plate inside vertex of the import is more than the inside of its lower plate Vertex, in operation, for the nitrogen that anti-nitration reaction generates in uphill process, part nitrogen can be imported ring-type by the upper plate of import In mud-water separating area (three-phase separation area), the mud-water separation effect in cyclic annular Disengagement zone is influenced, so as to influence SS removals；The device Water outlet directly communicated with cyclic annular mud-water separating area top, be easy to cause the mud for being discharged short stream and influencing cyclic annular mud-water separating area Water separating effect；The device is composed of three cylinder nestings, and structure is more complicated.
