It is formed by arranging a plurality of unit sewage treatment devices in parallel; each unit sewage treatment device comprises a biological selector, an anaerobic tank and an aerobic tank, wherein the anaerobic tank is a semi-sealed tank, devices such as an aerator and a sludge reflux pump are arranged in the aerobic tank, an overflow hole is formed in the tank wall between the biological selector and the anaerobic tank, and a communicating hole is formed in the tank wall between the anaerobic tank and the aerobic tank; an activated sludge outlet is arranged in the biological selector, and the activated sludge outlet is communicated with the sludge reflux pump through a connecting pipe; a parallel pipe connects the connecting pipes of the sewage treatment devices of all units together in parallel, and stop valves are arranged on the parallel pipe and the connecting pipes. The invention has the advantages that: when a certain unit sewage treatment device is overhauled, the activated sludge in the sewage treatment device is not wasted, and a large amount of manpower, material resources, funds and time are saved; when the sludge reflux pump fails, the adjacent sludge reflux pump can be used for continuous production.
Description
Technical field
The present invention relates to sewage treatment area, it is applicable to the sewage treatment process place that is provided with the requirement of mud reflux technique.
Background technology
Existing SBR sewage disposal device is set up in parallel by some separate unit waste disposal plants and forms.Each independently the unit waste disposal plant comprise biological selector, anaerobic pond, the Aerobic Pond of adjacent setting successively, be provided with duckbill valve in the biological selector, anaerobic pond is the semitight pond, be provided with aerator, instrument in the Aerobic Pond, strain hydrophone, sludge reflux pump and residual sludge pump, pipeline UNICOM is arranged, residual sludge pump and mud vent pipe UNICOM between duckbill valve and the sludge reflux pump.Pool wall top between biological selector and anaerobic pond is provided with some spillway holes, and the pool wall bottom between anaerobic pond and Aerobic Pond is provided with some linked holes.The processing technological flow of SBR sewage disposal device is: 1, sanitary sewage flows into biological selector after pipeline is collected, and sludge reflux pump work is meanwhile squeezed into biological selector and the sanitary sewage thorough mixing that newly advances with the mud in the Aerobic Pond; 2, overflow in the anaerobic pond with the spillway hole of the mixed sanitary sewage of mud by the biological selector side wall upper part, biological bacteria is grown in training in anaerobic pond, and makes its hunger; 3, the sewage that contains a large amount of hungry biological bacteria enters Aerobic Pond from the linked hole of anaerobic pond bottom, and more than 4,000 aerator aeration oxygenation in the Aerobic Pond bred biological bacteria fast; 4, water inlet, aeration are after two hours, and biological selector stops into water, and sludge reflux pump quits work, and aerator stops aeration, and sewage staticly settles; 5, precipitation is strained hydrophone and is begun to strain water after about one hour, drains from Aerobic Pond through the water that purifies, and strains about 40 minutes of water time; 6, the SBR sewage disposal device is idle about 20 minutes, begins circulation from flow process 1 again.
We find in actual use, the aerator in the Aerobic Pond, instrument, strain hydrophone, residual sludge pump and sludge reflux pump and are easier to damage.And after wherein any one device damages, because existing SBR sewage disposal device is set up in parallel the characteristics that form by some separate unit waste disposal plants, therefore the sewage production technique of whole unit waste disposal plant just finishes voluntarily, again device is carried out maintain and replace after mud must be removed in the pond.Mud in the Aerobic Pond is the active sludge through inoculation, cultivation and domestication success, it is tens days that the present needed time of a pond active sludge is grown in training, funds need hundreds of thousands of unit, waste active sludge and be the huge waste to human and material resources, financial resources and time.
Summary of the invention
The object of the present invention is to provide between a kind of unit waste disposal plant the communicated adjustment type sewage treatment equipment of returned sluge mutually.
Mentality of designing of the present invention is, in the sewage treatment process, the quantity of biological bacteria has a comparatively wide in range scope in the Aerobic Pond, therefore when the Aerobic Pond in a certain unit waste disposal plant need empty maintenance, can with the activated sludge pump in this pond in other unit waste disposal plant, continue to participate in producing, after Awaiting Overhaul finishes, with this pond of active sludge blowback, can resume production at once in the maintenance pond again; Simultaneously, if the sludge reflux pump in a certain unit waste disposal plant breaks down, and produce very busy can't break-down maintenance, can utilize the sludge reflux pump in the close unit waste disposal plant to keep this pond continuation production, when the active sludge in this pond exceeds standard, can use residual sludge pump to discharge.According to above-mentioned mentality of designing, technical solution of the present invention is: communicated adjustment type sewage treatment equipment, and it is set up in parallel by some unit waste disposal plant and forms; Each unit waste disposal plant comprises biological selector, anaerobic pond and the Aerobic Pond of adjacent setting successively, anaerobic pond is the semitight pond, be provided with aerator, instrument, instrument in the Aerobic Pond, strain hydrophone, sludge reflux pump and residual sludge pump, residual sludge pump and mud vent pipe UNICOM, pool wall top between biological selector and anaerobic pond is provided with some spillway holes, and the pool wall bottom between anaerobic pond and Aerobic Pond is provided with some linked holes; It is characterized in that: in biological selector, be provided with the active sludge outlet, between active sludge outlet and the sludge reflux pump pipe connecting UNICOM arranged; There is a parallel tubes together, on the parallel tubes between each pipe connecting, is equipped with stopping valve, on the pipe connecting between active sludge outlet and the parallel tubes, be provided with stopping valve the pipe connecting parallel connection of each unit waste disposal plant.
Advantage of the present invention is: owing to be provided with the active sludge outlet in biological selector, between active sludge outlet and the sludge reflux pump pipe connecting UNICOM is arranged; There is a house steward together, on the parallel tubes between each pipe connecting, is equipped with stopping valve, on the pipe connecting between active sludge outlet and the parallel tubes, be provided with stopping valve each pipe connecting parallel connection.Therefore, when certain unit waste disposal plant breaks down, in the time of need overhauling, as long as close in this unit waste disposal plant the stopping valve in active sludge exit, open the stopping valve on adjacent arbitrary parallel tubes, active sludge in the Awaiting Overhaul unit waste disposal plant will be pumped to and continue in other unit waste disposal plants to participate in producing, in case overhaul finishes, the active sludge allotment can be come again, compare former technology, saved a large amount of human and material resources and fund and time.Simultaneously, if the sludge reflux pump in a certain unit waste disposal plant breaks down, and produce very busy can't break-down maintenance, can utilize the sludge reflux pump in the close unit waste disposal plant to keep this pond continuation production, when the active sludge in this pond exceeds standard, can use residual sludge pump to discharge.
