Description
Technical field
The present invention relates to the dirty water decontamination handles fields, and in particular to a kind of effect processing entirely of the sewage based on MBBR and Magneto separate
System and method for.
Background technique
As the continuous of national environmental protection policy requirements was implemented in recent years, to accomplish fluently clear water defended war, quality of water environment is pushed
Lasting to improve, various regions watershed and local sewage drainage standard are further stringent.Under maximum discharge standard requirements, change traditional wastewater
High energy consumption, high resource consumption disadvantage are handled, seeks a kind of stably reaching standard, efficient low-consume, land occupation save, the simple sewage of operation and maintenance
Treatment process is the important development direction in the dirty water decontamination handles field.
Sewage disposal system in the prior art mainly includes MBR, MBBR etc., and the related research report of the prior art is main
Have:
CN106630393A discloses a kind of unattended IFAS or MBBR integrated equipment for sewage treatment and system, packet
Closed reactive tank, aerator and device for removing phosphorous by electrolysis are included, reactive tank is successively divided into biochemical reaction from side to the other side
Pond, sedimentation basin are filled with suspending carrier in biochemical reaction tank, and sewage enters from the water inlet being arranged on biochemical reaction tank,
It is connected between biochemical reaction tank and sedimentation basin and between sedimentation basin and filtering ponds, the water inlet pipe and precipitating of device for removing phosphorous by electrolysis
Pond connection, outlet pipe is connected to biochemical reaction tank, and biochemical reaction tank is divided into anaerobic pond, anoxic room, aerobic tank, to TN remove according to
Lai Yu reflux is unable to reach 80% or more nitrogen removal rate, while using device for removing phosphorous by electrolysis, sludge yield and consumption of electrode
Amount is big, and operating cost is high.
CN207259318U discloses a kind of integrated rural sewage disposal device, including tank body and below tank body
Mud room, wherein tank body includes from coarse rack room, fine fack room, MBR film process room and the oxidation successively separated from inside to outside
Coarse rack room is wrapped up in room, fine fack room, and fine fack room is wrapped up in MBR film process room, and the indoor sewage of fine fack is via the first overflow
In mouth overflow to MBR film process room, oxidizing chamber wraps up MBR film process room, and the indoor sewage of MBR film process is via the second overflow port
Overflow is to oxidizing chamber, the first mud discharging mouth of fine fack room bottom, the second mud discharging mouth and oxidizing chamber of MBR film process room bottom
The third mud discharging mouth of bottom leads to mud room.Setting suspension carrier in anoxic pond and aerobic tank, is separated by solid-liquid separation and uses MBR, first
It is short in the presence of suspension carrier service life, it needs to regularly replace, and replace complicated problem, secondly uses MBR, investment and operating cost
Height, and easily blocking, cause equipment to be unable to operate normally, and overhaul difficult.
CN206901993U discloses a kind of integration MBBR sewage disposal device, including sequentially connected anaerobic pond, lacks
Oxygen pond aerobic tank and sedimentation basin, however, the not set advanced treatment unit of equipment, sedimentation basin is discharged direct emission, and effluent index is outstanding
Its TP, SS are unable to reach level-one A standard.
CN109553196A discloses a kind of anaerobic-aerobic multiple-hearth biofilm reactor and its technique, including reactor
Tank body, reactor tank body are embedded in backfill, and the bottom of reactor tank body is provided with fine sand basal layer and concrete foundation
Layer, the inside of reactor tank body, which divides, anoxic zone, anaerobic zone, aerobic zone, settling zone and filtering sterile zones, and mating is provided with
Aerating system and electric-control system, the MBBR biological suspension that different proportion quantity is added in anoxic zone, anaerobic zone, aerobic zone carry
Body, pure film MBBR technique are low to colloid in raw water and particle utilization of carbon source, and carbon source deficiency causes biological carbon and phosphorous removal limited, pure film
Process requirement secondary settling tank needs timing to backwash, influences technique continuous and steady operation using filter tank as advanced treating.
CN106348528A discloses a kind of magnetic load precipitating and biological aerated filter compound sewage processing system, including magnetic
Precipitation unit and biological aerated filter unit are loaded, its working principle is that dosing tank and magnetic separator are respectively to magnetic-coagulation reactor
Middle addition coagulant, flocculant and magnetic powder, treatment sewage is entered in magnetic-coagulation reactor by water inlet takes off steady flocculation, then
Into first treated is completed in inclined-tube sedimentation tank, most of phosphorus, suspended matter and partial organic substances are removed, subsequently enter aeration life
Object filter tank removes ammonia nitrogen and partial organic substances, to realize the secondary treatment of sewage.System design is not in view of removing total nitrogen
It removes, does not meet existing discharge standard requirement.
Biochemical treatment is carried out using activated sludge process merely, is difficult to reach in the rough sledding such as water inlet impact and winter low temperature
Mark discharge, system loading is low to be taken up a large area；MBR technique membrane module needs timing on-line cleaning, periodically backwash, and there are costs
It is high, energy consumption is high, the disadvantages of needing special messenger to safeguard, be badly in need of improving；MBBR technique needs mating advanced treatment process such as efficient sedimentation tank, filter
Pond has process flow long, the disadvantages of taking up a large area, is unfavorable for the highly integrated property of technique.
To improve quality of water environment, realizes that stable water outlet is up to standard and equipment high efficiency low consumption simple operation, be badly in need of to existing dirt
Water treatment system improves.
