Description
Technical field
The technical field of the sewage disposal of the present invention involved by civil engineering work and environmental engineering, particularly relates to a kind of settlement of sewage filtering basin of sewage work's advanced treatment.
Background technology
Along with country is to the raising of sewage work's discharge standard-required, most newly-built sewage work all will reach the emission standard of one-level A, many built sewage works also want upgrading, reach the emission standard of one-level A, therefore in design and construction process, advanced treatment of wastewater facility is all related to, at present, advanced treatment of wastewater adopts usually to the water outlet of secondary sedimentation basins through dosing coagulating sedimentation and after filtering, the pollutent such as suspended substance, phosphorus in further removal sewage, discharges after reaching one-level emission standard A.
Advanced treatment of wastewater coagulating sedimentation filtering system of the prior art is primarily of the composition such as coagulative precipitation tank and filter tank.Wherein, coagulative precipitation tank has dosing mixing zone, flocculation zone, settling region, mud scraper, sludge recirculation system etc. usually, be by dosing coagulant and the organic pollution materials in sewage fully mix contact and and then by the place of its mud-water separation.The effect of dosing mixing zone, flocculation zone coagulating agent and organic pollution materials is fully mixed contact, and forms cotton-shaped particle; The effect of settling region makes mud-water separation, and after process, sewage is discharged by effluent weir; The effect of mud scraper is that the mud of precipitation is effectively discharged; The effect of sludge recirculation system be part is discharged sludge reflux to reaction zone, improve mud mixing contact effect.Filter tank is conventional is filtering cloth filtering pool and sand filter, because filtering cloth filtering pool floor space is little, head loss is few, applies more.Filtering cloth filtering pool is made up of filter cloth dish and back-purge system, and the effect of filter cloth dish is filtered sewage, and the residue on filter cloth is removed in the effect of back-purge system, keeps the clean of filter cloth.After the process of dosing coagulating sedimentation filtering system, in sewage, the pollution substance such as SS, P all can reach one-level emission standard A.
In traditional wastewater coagulating sedimentation filtering system, coagulating sedimentation and to filter be in 2 different structures, each pond inner and between pipe duct or aperture connect the head loss produced generally can more than 2 meters, sewage work's gross head loss is made to increase a lot, in the project of upgrading and rebuilding of particularly existing sewage work, because original Tail water reuse reserves head seldom, often need to promote for 2 times.
In the wastewater coagulating sedimentation pond of routine, to need the partial sludge of discharging through pump reflux to flocculation zone, to improve sludge concentration in pond, ensure sludge settling effect, effluent weir will have certain free-electron model height, prevents subsequent disposal or discharge from affecting sedimentation effect.
In the filtering cloth filtering pool of routine, filter type goes out in exceptionally entering and enters to go out 2 kinds with interior, the corresponding employing vacuum take-off of filter cloth back flushing and hydrodynamic cleaning two kinds, vacuum take-off due to the sealing of suction nozzle outer rim and filter cloth more difficult, cause back flushing water loss larger, hydrodynamic cleaning requires to suspend the filtration being rinsed part when rinsing, and reduces filtration useful area.
Several situation can cause cost of sewage disposal to increase above, need certain floor space, special in existing sewage work upgrading, Tail water reuse nervous to some lands used reserves the few project of head, traditional more difficult adaptation of wastewater coagulating sedimentation filtering system.
