The utility model discloses an advanced waste treatment system includes reactor, inlet tube, water pump, water distribution dish, intake pipe, air pump, gas distribution dish, light filler, scum pipe, outlet pipe. A serial communication port, this intermittent type formula air supporting - biofilm reactor advanced waste treatment system contains a reactor, it packs to be equipped with lightweight plastic in the reactor, through to carrying out the aeration in the waste water, make the light suspension filler in the reactor be the fluidization state, the pollutant at first can be got rid of through the little biodegradable who adsorbs on packing attached to the light, afterwards, the degradation residue floats to the reactor top through the buoyancy of air supporting, get rid of through row sediment, this system can carry out the advanced treatment to the petrochemical wastewater.
Description
Technical field
The utility model relates to a kind of intermittent type air supporting-biofilm reactor advanced waste treatment system, for sewage disposal, belongs to field of environment protection.
Background technology
Petrochemical wastewater is one of current the most unmanageable trade effluent of generally acknowledging.Therefore, be 100mg/L to the first discharge standard limit value of general waste water in the discharge of China national standard integrated wastewater, and for petrochemical wastewater, then setting separately its first discharge standard is 160mg/L.
At present, for the advanced treatment of petrochemical wastewater, mainly contain membrane treatment process, BAF technique and advanced oxidation processes etc., advanced treatment is carried out to existing petrochemical wastewater, thus improve effluent quality.But all there is the shortcomings such as disposable and operation cost is high, complicated operation, treatment effect are limited in these techniques.Therefore, a kind of simple and effective, advanced waste treatment system with low cost and apply in petrochemical wastewater process and seem particularly important is invented.
Air supporting is a kind of method of solid-liquid and liquid-liquid separation.For solid-liquid air supporting, detailed process passes into air first in a liquid, and produce a large amount of micro bubble by air releasing device and float, the pollution substance afterwards in liquid is then attached on bubble, by pneumatically supported buoyancy, pollution substance is removed after floating.
Biomembrance process is the method belonging to easy-to-keep biological process, and it is by waste water by aerobic microbiological and protozoon, and the microbial film that growth and breeding is formed on carrier filler such as metazoan, absorption and degradation of organic substances, make the method that waste water is purified.According to the difference of device, biomembrance process can be divided into four classes such as biological filter, blodisc, contact oxidation method and biological fluidized bed.In the wastewater treatment of oil and chemical industry, wherein applying maximum is contact oxidation method.
Before the 1950's, biomembrance process is not but taken seriously always, and its reason is mainly because the biomembrance process structures that adopt the earliest take rubble as the trickling filter of filler in producing.The specific surface area of rubble is little, can be that the surface-area of attached growth of microorganisms is little, and thus the load of trickling filter can not be very large, and make its floor space comparatively large, sanitary condition is also bad.The fifties, because biofilm treatment system introduced by the development of plastics industry and plastic filler, biomembrance process is occurred many significant development.Therefore, there is much novel biomembrance process equipment.
Utility model content:
All there is the shortcomings such as disposable and operation cost is high, complicated operation, treatment effect are limited in the advanced treatment process for existing petrochemical wastewater, the utility model provides a kind of intermittent type air supporting-biofilm reactor advanced waste treatment system, have employed the mode of intermittent operation, by the combination of biomembrance process and By Bubble-floating Method, advanced treatment is carried out to petrochemical wastewater, there is the features such as process waste water running cost is low, removal efficiency is high, structure is simple, easy to operate.
The utility model solves the technical scheme that its technical problem adopts:
A kind of intermittent type air supporting-biofilm reactor advanced waste treatment system, comprises reactor, water inlet pipe, water pump, water distributing tray, inlet pipe, air pump, air-spreading disk, light filler, scum pipe, rising pipe.It is characterized in that, described intermittent type air supporting-biofilm reactor advanced waste treatment system contains a reactor.Described reactor bottom is inlet pipe, and inlet pipe is connected with air pump.Described air-spreading disk is positioned at above inlet pipe, and air-spreading disk has qi-emitting hole.Described water inlet pipe is positioned at above air-spreading disk, and is connected with water pump.Described water distributing tray is positioned at above water inlet pipe, and water distributing tray has water distributing pore.Described light filler is positioned at above water distributing tray.Described rising pipe is positioned at above light filler.Described scum pipe is positioned at reactor head.
The beneficial effect of the technical scheme that utility model embodiment provides is:
The utility model is provided with light plastic filler in a reactor, by carrying out aeration in waste water, the light suspended filler in reactor is made to be fluidized state, first pollutent is removed by the microbiological deterioration be attached on lightweight adsorption stuffing, afterwards, degraded residue floats to reactor head by pneumatically supported buoyancy, removed by deslagging, this system can carry out advanced treatment to petrochemical wastewater, has the advantages such as process waste water running cost is low, removal efficiency is high, structure is simple, easy to operate.
