Embodiment
The utility model is described in further detail below in conjunction with embodiment:
As Fig. 1, shown in 2, water recycling device in a kind of hydraulic type, comprise the dirty pond 1 of collection, the equalizing tank 2 that links to each other by the dirty pond 1 of pipeline and described collection, secondary water treating pond 3 that links to each other with described equalizing tank 2 the other ends by pipeline and reuse water tank 4 and the sludge sump 5 that links to each other with described secondary water treating pond 3, diving impeller 6 is housed in the described equalizing tank 2, on the pipeline between described secondary water treating pond 3 and the equalizing tank 2 lift pump 7 and y-type filter are housed, be soaked with MBR membrane reactor 8 in the described secondary water treating pond 3, film in the described MBR membrane reactor 8 is the PVDF flat sheet membrane, chemically-cleaning device 9 is equipped with in described secondary water treating pond 3 outsides, described chemically-cleaning device 9 links to each other with described MBR membrane reactor 8 by header 10, be provided with hydraulic pressure circulation flushing device in the described secondary water treating pond 3, described hydraulic pressure flushing arrangement comprises hydraulic pressure flushing pipe 11 and is installed in aeration tube 12 below the described hydraulic pressure flushing pipe 11 that described aeration tube 12 outer ends are connected with blower fan 13.
Between described chemically-cleaning device 9 and the described MBR membrane reactor 8 electrically operated valve 14 is housed.
Water recycling device is provided with the equipment room 15 that the Q235-A carbon steel material is made outward in the described hydraulic type, described equipment room 15 inwalls are the steel plate that three cloth, four oily reinforced plastics are made, be brushed with twice rust-inhibiting paint and twice finish paint after the described equipment room 15 outer wall derusting by sandblast, the water recycling device system is by the industrial computer intelligent control in the described hydraulic type.
Principle of work: in hydraulic type in the water recycling device process system, the waste water that collects in the dirty pond is removed the bulk foreign material through grid earlier before flowing into equalizing tank, protects equipment such as follow-up water pump not blocked.Equalizing tank has the long residence time, can suitably inoculate the oxygen activity mud of holding concurrently, and the double hydrolytic tank of doing uses, and sewage thorough mixing under the effect of diving impeller is even, under the effect of the oxygen bacterium of holding concurrently organic difficult degradation macromolecular substance is hydrolyzed into small organic molecule.Sewage again by water pump lifting to the MBR reactor, y-type filter filtering finely ground particles is set in the pipeline.
Equalizing tank sewage is delivered to the hydraulic pressure flushing pipe by lift pump, the pressurized air thorough mixing that High-Pressure Water that lift pump produces and blower fan are carried, form turbulent flow, membrane module draws water by the procedure auto-control suction pump, active sludge is blocked on the film surface, flat sheet membrane has had hydraulic pressure to clean and the cleaning of blower fan aeration, and cleaning is recovered on the film surface faster.Clear water after the suction drains into the reuse water tank.Enter for operation blower fan, the lift pump of keeping system and normally open when equalizing tank is anhydrous, electrically operated valve switches to the internal recycle state, and the carbonated drink turbulent flow that same parameter hydraulic pressure combines with pressurized air is implemented cleaning to the film surface.
Active sludge is constantly bred in MBR reactor for treatment process, discharges mud automatically to sludge sump by the water quality in-line meter, and from flowing into equalizing tank, regularly extract out by fecal suction truck by mud through the post precipitation supernatant liquor for mud in the sludge sump.When flat sheet membrane surface slight pollution, transmit signal by suction pump suction inlet vacuum pressure transmitter pressure to intelligence controlling device, send instruction and close suction pump, start automatic flushing device, adopt clear water to clean flat sheet membrane and can recover normal use; Clean final vacuum pressure registration can't reduce the time when water is counter, start chemical agent automatically and clean, carry out matting with citric acid, clorox respectively, scavenging solution enters equalizing tank by suction pump, clean finish after system recovery move.
