Embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is done specific descriptions.
Fig. 1 is the structural representation of the utility model.
The utility model comprises mechanical grille 1, settling pit 2, equalizing tank 3, biofloculation pond 4, BAF 5, high efficiency filter pond 6.
Be connected through pump between said equalizing tank 3 and the biofloculation pond 4; Sewage in the equalizing tank 3 is through pump input biofloculation pond 4; Mud in the biofloculation pond 4 pumps into sludge dewatering equipment 8 through pump; Be provided with pump between the import of the water port in biofloculation pond 4 and BAF 5; Treat that further the water of processing is squeezed into BAF 5 through pump, water got into clean water basin 7 through high efficiency filter pond 6 during BAF 5 exits were treated, also was provided with ClO at the water inlet place of clean water basin 7
2Producer 9, clean water basin 7 are provided with water discharge line and back flushing pipeline, and the part clear water in the clean water basin 7 is used for reuse or discharging through water discharge line, and the part clear water is used for back flushing through the back flushing pipeline.
Device in the face of the utility model is elaborated down.
Said mechanical grille 1 is in order to thicker dispersed suspended solids in the interception waste water, and it mainly acts on the impeller that is to protect pump, guarantees the normal operation of subsequent disposal structures.
The pre-treatment in addition of 2 pairs of waste water of said settling pit; Its effect is the bigger inorganic particle of partition density from waste water, avoids wearing and tearing with protection water pump and pipeline, dwindles sludge treatment structures volume; Improve the rate that contains of mud organic constituent, improve the value of mud as fertilizer sources.
Said equalizing tank 3 is the sewage thorough mixing, because sewage water quality, the water yield are inhomogeneous, the different times wastewater flow is bigger with the pollutant load fluctuation, and equalizing tank 3 can guarantee that the continous-stable of subsequent disposal facility moves.
The 4 couples of SS in said biofloculation pond have higher removal; Can improve the biodegradability of sewage, also part that can be removed organism, aerobic sludge gets into the biofloculation pond; There is the good treatment effect in the biofloculation pond to mud, and the sludge volume in biofloculation pond reduces more than 30% than settling tank system.The organic content of biofloculation mud, sanitary index, sedimentation and dewatering all the digester mud with traditional are suitable, and mud reaches degree of stability, and mud is discharged after processed in the biofloculation pond, and the dewatered sludge water ratio is about 75～80%.Can be used as fertilizer uses or transports outward with car.
It is three zones that BAF 5 is divided into from structure: buffering water distributing area, supporting layer and filter material layer, exhalant region and effluent trough; The use of said BAF 5 a kind of new particulate filtrate 11, in its surface growth microbial film is arranged, the bottom-up filtrate 11 that flows through of sewage provides aeration by aerating system, makes organism in the waste water obtain absorption, hold back and biolysis; Treatment sewage flows into the buffering water distributing area by pipeline; Sewage is when upwards flowing through filter material layer; In the pond, supply with the required oxygen source of microbial film metabolism (air) by the gas blower air blast and through aeration tube simultaneously; The microbial film that is grown on the filtrate 11 is drawn the solubility organic pollutant as the required nutritive substance of its physiological activity from sewage; In metabolic process, organic pollutant is decomposed, sewage is purified, after the microbial film purifying treatment of apposition growth on the filtrate 11, discharge by pipeline through exhalant region and effluent trough; When BAF runs to a certain degree,, can have the microbial film that part comes off in the water outlet owing to thicken coming off of microbial film on the filtrate; Make the effluent quality variation, this is to close the water inlet pipe valve, starts backwash pump; Utilize the treat effluent of deposit in clean water basin that back flushing is carried out in the filter tank, when filter back washing, lighter filtrate 11 possibly brought to the water outlet place by current; And in the sedimentation of sloping plate deposition district; And be back in the filter tank, to guarantee the microorganism concn in the filter tank, the angle of inclination of the swash plate 10 of tilted plate separator is set to 75 ° ~ 90 °; Can be taken out of outside the pond with current when operation or the back flushing with the microbial film that guarantees to come off, filtrate then can not taken out of outside the pond; Gas-water associating back flushing is adopted in back flushing, and is even for guaranteeing water distribution, gas distribution, on the filtrate back up pad, evenly is furnished with BAF special-purpose water distribution, distribution filter;
The filtrate 11 of the filter material layer of said BAF 5 is novel small dia particulate filter, can effectively improve the microbe population and the activity of adhering to, and improves the processing power in filter tank, and processing efficiency and effect significantly improve, and microbial biomass reaches 10--15g/l.
Said high efficiency filter pond 6 employing small dias, the filtrate that filtration resistance is little, specific surface area is big; Impurity particle and the touch opportunity of filtrate and the adsorptive power of filtrate in the water have been increased; Thereby filtration efficiency and retaining power have been improved; Advantages such as it is fast that this filtration unit also has filtration velocity simultaneously, and floor space is little, stable operation is simple.
Because the water after handling is used for landscape water and greening water, consider the characteristics of its water, establish reuse clean water basin 7 and regulate retaining, to satisfy reuse and back flushing requirement.
The utility model is provided with the recoil pipeline, and when filter material layer is contaminated when needing cleaning and regeneration, used water is cleaned easily, to recover the strainability of filter unit effectively, guarantees sewage treatment effect.
For reducing the sound pollution of Sewage treatment systems; The utility model adopts the underground type structure; Equipment such as gas blower and water pump are placed in the underground pipe gallery, in civil Engineering Design, adopt sound absorbent material simultaneously, equipment all is provided with vibration-control system when installing; All adopt flexible joint at equipment and pipeline junction, reduce vibration, reduce noise.
The utility model adopts following technical process to the sink drainage processing feature:
Sewage gets into settling pit 2 through mechanical grille 1; Get into equalizing tank 3 through settling pit 2 pretreated sewage; Sewage is squeezed into biofloculation pond 4 through pump behind the thorough mixing in equalizing tank 3, mud gets into sludge dewatering equipment 8 through mud discharging mouth to be continued to handle, and has removed the sewage of partial organic substances and has squeezed into BAF 5 through pump; Treatment sewage is flowed into the buffering water distributing area of BAF 5 by pipeline; Sewage is upwards flowing through filter material layer, after the microbial film purifying treatment of apposition growth on the filtrate 11, discharges entering high efficiency filter pond 6 through exhalant region and effluent trough by pipeline, after ClO2 producer 9 gets into clean water basin 7; Reuse of part clear water or discharging, part clear water are used for recoil through the recoil pipeline and clean.
The utility model adopts biofloculation pond associating BAF waste disposal plant; The 4 couples of SS in biofloculation pond have higher removal; Can improve the biodegradability of sewage, also the part that can be removed organism improves working condition, the reduction load of follow-up high efficient aeration biological filter.
