Vacuum controller is cursory as one on the liquid level E water level of filter tank, and top can be fixed on the top wall of filter tank by stationary bearing.An inner suitable flap C is suspended on the point of fixity F point fixed spring D.The filter tank is with the increase of working time, and filtering layer contains dirty ability and increases, so under the effect of spring D, cause that into the cross section of air reduces to cause h
1Increase, the air inlet of drainage siphon TOP is reduced, the filtration water yield is invariable, works as h
1During=H by vacuumometer be the filter tank then begin the flushing.Play the automatic compensating action of head loss so vacuum controller is very sensitive, safe.Therefore make conventional filter tank for the water that guarantees the above head loss value of filtering layer almost all removes, make pond body decline 1.5～2.0m.Installing the band standard output signals in view of vacuum meter can make the filter tank realize control automatically or intelligent control easily.
Transmission ﹠ distribution water pressure pipeline adopts the tubing of internal diameter 3mm～10mm.
Former water enters the flash mixing tank through former water water inlet pipe, and drug-throwing chamber adds mixture and conditioning agent in the flash mixing tank.Water enters the automatic reaction pond by top behind flash mixing tank thorough mixing.Flow into the air supporting reaction tank through the reaction of high order pond and fully react, enter Lan Meila separator top, water carries out solid-liquid separation at the Lan Meila separator, and separated water turns back to the top of Lan Meila separator.Water after the Lan Meila separator separates enters from the top of Lan Meila separator and gives ozone reactor.Water and ozone fully react the back and flow out the bottom that enters secondary flash mixing tank from the bottom of ozone reactor, and the water of drug-throwing chamber in entering secondary flash mixing tank continues filling mixture and conditioning agent.Flow out the distributing trough that enters biochemistry pool by the top of secondary flash mixing tank behind the thorough mixing, distributing trough is distributed to primary reaction chamber equably with water.Slowly stir through agitating vane at primary reaction chamber, make water obtain continuously, evenly, abundant contact reacts, according to requirement in batches, change the velocity variations of control biochemistry pool top variable-frequency motor variator by between 1～9 times of water inlet.Impeller rises to the second order reaction chamber with the water of primary reaction chamber, the flow deflector of second order reaction chamber is broken being synchronized with the movement of water, make water continue fully reaction, water enters diversion chamber from the pod apertures of second order reaction chamber, enters the contact separation chamber in the water yield of one times of water source ratio by separating opening.The water on stopping composition top, contact separation chamber evenly enters the receipts tank through eyelet, enters total water leg inflow ozone reactor by receiving tank.Effusive another part water yield is then in batches indoor by being back to primary reaction through the seam that refluxes of 1～9 times in former water through the diversion chamber bottom, circulation repeatedly successively.Biochemical reaction tank is got rid of deactivated sediment through long-play from the bottom of drain cap.
Make it into one times of water yield, take out one times of water yield again, 1～9 times the water yield is returned again, so continuously, in batches, reflection to be to reach the purpose for the treatment of water.
Water after biochemistry pool fully reacts the ammonia nitrogen of removing in the water is flowed out by the total water leg in biochemistry pool top, enters the top of ozone reactor through hydraulic pipe.After fully reacting with ozone, be transported to the top of sand filter by hydraulic pipe from the bottom of ozone reactor, water after filtering enters the top of activated carbon filter and carries out adsorption filtration from the bottom of sand filter, remove heavy metal contaminants and other organic pollutants.Activated carbon filter bottom hydraulic pipe is transported to three grades of ozone reactors with water, is transported to tank after ozone and water fully react sterilization again, is entering tank import position by the drug-throwing chamber preservative clo that annotates
2With accent taste agent co
2, the tank of restoring.Enter water distributing network, transmission ﹠ distribution water pressure pipeline to user's water outlet water nozzle outflow ultra-clean direct-drinking water through conveying pump high pressure, sealing.
The effusive water in the bottom of activated carbon filter is input to the ultrafiltration membrance filter device or is input to the nanofiltration membrane strainer or is input to the ultrafiltration membrance filter device and that filter membrane, and the water after filter membrane is handled is by three grades of ozone reactors of rising pipe input.The filter membrane of ultrafiltration membrance filter device and nanofiltration membrane strainer can adopt microfiltration membrane (Microfiltration-MF) or ultra-filtration membrane (ultrafiltration-UF) or nanofiltration membrane (Nanofiltration-NF) or reverse osmosis high-pressure film (Reverse Osmosis-RO) or electrodialytic membranes (electrodialysis-ED).
The sediment that is separated mud and biological process at scavenging process enters sludge sump through the mud pipeline, stirs to make through agitator to have active supernatant liquor and be recovered to blowoff basin through hydraulic pipe.All enter into blowoff basin through hydraulic pipe and ultra-filtration membrane and nanofiltration membrane technology self-cleaning wash-down water in service through hydraulic pipe from the wash-down water of sand filter and activated carbon filter draining, two blowoff basins and alternate run are set, one of them is as the recovery of water, and another is then as draining.Agitator is set in the blowoff basin, and agitator stirs the water that has active flco, reclaims through hydraulic pipe and wash-down water recovery lift technique in source water flooding quantity ratio.Lift technique reclaims draining and wash-down water in former water ratio.Water to lose activity in mud under the deposition in the spoil disposal pond and the blowoff basin sediment and back flushing ultra-filtration membrane and back flushing nanofiltration membrane is discharged outside the factory by the road.
The range of application of membrane process can expand high pressure reverse osmosis membrane (Reverse Osmosis-RO) or electrodialytic membranes (electro dialysis-ED) technology to, and can reclaim film self-cleaning wash-down water, thereby saves wash water greatly.
When former water contains the light contamination thing, can select microfiltration membrane (being Micro filtration-MF) for use, remove the pollution substance of microorganism and bacterial count magnitude; When former water contains the pollution substance that is harmful to poisonous and carcinogens and viral load level, can select ultra-filtration membrane (ultra filtration-UF) for use, remove pollution substance harmful poisonous and carcinogens and viral load level; When former water contains hardness, fluorochemical exceeds standard and water when the divalent ion materials such as hardness, vitriol, fluorochemical and muriate that puckery, bitter, saline taste road etc. is harmful and mouthfeel is uncomfortable are arranged, can select nanofiltration membrane (Nano filtration-NF) for use.If the water quality of former water contains under the condition that index is too high or nanofiltration membrane is difficult to adapt to that individually low molecules such as hardness, muriate and fluorochemical or ion cause, also can adopt the high pressure reverse osmosis membrane (Reverse Osmosis-RO) or electrodialytic membranes (electrodialysis-ED) the treating part water yield to mix to reach water quality standard to be transported to the user again.Adopt membrane filtration to have the condition of recycle-water resource, can flow into blowoff basin to the water of film self-cleaning flushing in service and reclaim, periodically the film backwashing water is then drained or is used it for anything else.It is as shown in the table for the leading indicator of tap water and European Community's index.
