Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of regeneration effluent system provided by the utility model.
Detailed description of the invention
In order to make those skilled in the art be more fully understood that this utility model scheme, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Refer to Fig. 1, a kind of regeneration effluent system that this utility model provides, including collecting-tank, regulating reservoir, hydrolysis acidification pool, anaerobic pond, anoxic pond, Aerobic Pond, membrane bioreactor, nanofiltration equipment and disinfection pool. The sewage of city discharge pumps into grid collecting-tank after collecting, and sets fine fack at collecting-tank water inlet end, removes large granular impurity, plays and prevent occluding device and affect wastewater treatment efficiency. Sewage with after pump into regulating reservoir through variable frequency pump, regulating reservoir obtains homogenizing and all measures. Pond adopts boring aeration pipe stirring, it is prevented that sludge settling. Regulating reservoir sets one-level elevator pump and is processed to hydrolysis acidification pool by sewage lifting, hydrolysis acidification pool is to utilize hydrolytic bacteria and acidification bacteria that the protein in sanitary sewage, saccharide and fats organic pollutant are hydrolyzed under anaerobic environment to react and acid-producing, insoluble substance is made to be hydrolyzed into dissolved matter, and and then macromolecular substances open loop chain rupture is become small-molecule substance, primarily become butanoic acid, propanoic acid, acetic acid, improve the biodegradability of sewage, organic pollution is made to be more easy to by subsequent biochemical microbial degradation, thus stably reaching standard discharge. Meanwhile, in pond, water inlet formation net is caught by mud, absorption, oxidation, carries out float and colloidal substance effectively intercepting and clarification. This process, owing to not consuming additionaling power, has good energy-saving effect. Mud in hydrolysis acidification pool is admitted in sludge concentration tank carries out subsequent treatment finally by spoil disposal outlet.
Hydrolysis acidification pool water outlet passes sequentially through anaerobic pond, anoxic pond and Aerobic Pond (i.e. A2/O pond) and processes, and A2/O cell system can abundant organics removal and sewage is carried out denitrogenation, dephosphorization.Aerobic Pond is additionally provided with sewage backflow outlet and sludge reflux outlet, sewage mixed liquor after the process of part Aerobic Pond is sent back to anoxic pond from sewage backflow outlet through reflux line and proceeds biochemical reaction process, the mud part produced in Aerobic Pond is sent to sludge concentration tank and processes, and another part mud that water content is bigger is sent back to anaerobic pond through sludge reflux outlet and proceeds circular treatment.
The mud collected in sludge concentration tank is after precipitate and separate, supernatant is sent back to regulating reservoir and is circulated sewage treatment process, and the mud after precipitating is admitted to sludge dehydration device and carries out the moisture content of the cake after the concentrated processed of dehydration up to below 60%-70%, it is then delivered to outward transport or landfill.
Sewage, after A2/O cell system removes major part Organic substance, enters MBR pond, and major control index in MBR pond includes: water inlet C:N:P=(350-500): 5:1, temperature controls at 30-35 DEG C, and pH value controls at 7-7.2. The water outlet of MBR pond enters nanofiltration equipment and is filtered, and the concentrated solution that period produces can recharge or return spray. Process the water after reaching reuse standard through nanofiltration equipment and enter sterilization pool sterilization, then discharge or be recycled. This system also can arrange ultraviolet sterilization device (not shown) outside the outlet of nanofiltration equipment, is re-fed into disinfection pool and carries out disinfection, to improve sterilization effect after the water source after nanofiltration is carried out ultraviolet-sterilization process.
Testing through reality, the stable effluent quality of native system, various indexs all reach reclaimed water standard.
Above a kind of waste water recovery system provided by the utility model is described in detail. Principle of the present utility model and embodiment are set forth by specific case used herein, and the explanation of above example is only intended to help to understand core concept of the present utility model.
