Between be additionally provided with a sewage pretreatment device, be connected to water producing tank and a concentrated water after the reverse osmosis unit
Pond；The reverse osmosis unit outer surface is provided with rupture pressure disc, and the reverse osmosis unit is provided at both ends with delivery port and water inlet；Institute
State delivery port and water inlet is both provided with non-return valve；A low-temperature reduced-pressure enrichment facility is also associated with behind the concentrated water pond.
Preferably, the reverse osmosis unit is connected with 3 supply-water pumps, and supercharging is provided for system.
Preferably, the water producing tank is connected with two ultraviolet sterilizers.
Preferably, the reverse osmosis unit is also associated with a chemically-cleaning device, and the chemically-cleaning device is by cleaning
Case and cleaning pump, cleaning filter and its pipe arrangement composition；The cleaning case divides permeability apparatus to be connected by pipe arrangement with described.
Preferably, the counter-infiltration system is connected with a chemicals dosing plant.
Preferably, the water producing tank 2, volume 50m3。
Preferably, water inlet pipe, outlet pipe, overflow pipe, evacuated tube, respiratory siphon and an interface are provided with the water producing tank
Flange.
Preferably, the source pond is 2, is respectively 50m sequentially for the first source pond and the second source pond, volume3；By
The height of water level that first pond enters is higher than the second pond, and each source pond is designed with recycling the bottom valve of water.
It is more highly preferred to, the supply-water pump is variable frequency water supply pump.
The above-mentioned technical proposal of the present invention has advantages below compared with prior art：It is cost-effective that circuit board waste water is entered
Row processing and reuse, strict categorised collection processing and pair can the cleaning waste water of reuse carry out independent reuse, ensure waste water recycling
System can stable operation key point.The characteristics of according to PCB industry production processing procedures, the cleaning of washing step in procedure for producing
Water usage amount will account for 70% or so of whole Workshop Production water, and the part water is mainly containing copper powder, copper ion, inorganic acid (sulphur
Acid), inorganic salts, a certain amount of COD and other heavy metal ion.By handling this part rinse water, can be achieved completely useless
Water circulation, reach the effect of emission reduction and recycling economy, greatly reduce sewage discharge expense.Ultraviolet sterilizer can be by production water
Bacterium kills, and recycle-water bacterial regrowth is met tenderer with water requirement.The effect of reuse water tank is by by reverse-osmosis treated
Water afterwards is collected in reuse water tank, plays a part of buffering and regulating pondage.Supply-water pump provides power for the conveying of recycle-water；
The system has great market prospects and economic value.
