Embodiment
Below in conjunction with accompanying drawing the utility model is done to describe further.
Fig. 1 is wherein a kind of specific embodiment of the utility model.
As shown in fig. 1, hospital sewage treating apparatus of the present utility model, include agitation vat 2, medicine storing pot 8, dechlorination pharmacy jar 17, ejector 10, mixing tank 12, chlorine residue meter and pH value tester 20, in agitation vat 2, be provided with agitator 7, agitation vat 2 tops are provided with dispensing mouth 3 and water inlet pipe, are provided with electrically-controlled valve 1 on water inlet pipe; Be provided with discharge nozzle in the bottom of agitation vat 2 and be connected, on discharge nozzle, be provided with electrically-controlled valve 5 with medicine storing pot 8; The blow-off pipe of agitation vat 2 bottoms is connected with medicine storing pot 8, is provided with electrically-controlled valve 6 on blow-off pipe; Medicine storing pot 8 is provided with water inlet pipe, is provided with electrically-controlled valve 4 on water inlet pipe; The discharge nozzle of medicine storing pot 8 is connected with mixing tank 12, is provided with electrically-controlled valve 11 on discharge nozzle; Ejector 10 is connected with sewage water inlet pipe 9 on one side, and the other side is connected with mixing tank 12; The water shoot 13 of mixing tank 12 is connected with sterilization exposure chamber 21, is provided with the probe of chlorine residue meter 14 on water shoot 13, and the delivery pipe of sterilization exposure chamber 21 is connected directly to discharge outlet 22, is provided with the probe of chlorine residue meter 15 and the probe of pH value tester 20 at discharge outlet 22; Dechlorination pharmacy jar 17 is provided with dispensing 16; The discharging chemical feed pipe 19 of dechlorination pharmacy jar 17 bottoms is connected to discharge outlet 22, is provided with electrically-controlled valve 18 on chemical feed pipe 19.
When the utility model specifically uses, at first disinfectant is dropped in the agitation vats 2 from dispensing mouth 3, open electrically-controlled valve 1, close electrically-controlled valve 4,5,6 simultaneously, tap water flows into agitation vat 2, starts agitator 7 and makes tap water and disinfectant thorough mixing, stirs and closes electrically-controlled valve 1 after three to five minutes, open electrically-controlled valve 5, the disinfectant for preparing flows into medicine storing pot 8; According to the requirement that the proportioning and the sewage quantity of medicament dilutes, electrically-controlled valve 5 is closed, open electrically-controlled valve 4, flow into tap water to reach the dilution purpose; This stage is the dosing stage.
Subordinate phase is the main reaction stage, with sump pump sewage is entered coupled ejector 10 from sewage water inlet pipe 9, because sewage enters ejector 10 at a high speed, produces negative pressure, and outside air enters and mixes with sewage, can reduce the CODcr of sewage; Open electrically-controlled valve 11 this moment, and thimerosal and air water blended sewage enter mixing tank 12 simultaneously, enters the sterilization exposure chamber by water shoot 13 again; This stage is gas, water, medicine mix stages, is also referred to as to reduce CODcr, sterilization stage.
After said procedure was finished, chlorine residue meter 14 just can demonstrate the chlorinity in the combined sewage; Usually the chlorinity of sewage sterilization requirement, just need be adjusted the dispensing part as surpassing or being lower than this content at 4mg/1-5mg/l.Chlorine residue meter 15 is to be used for the sewage at last discharge outlet 22 places is monitored by the residual chlorine amount requirement of state sewage emission standard, remain on below the 0.5mg/l, will adopt the phase III to remove residual chlorine amount as surpassing this standard: the medicament that will remove chlorinity in advance is in dispensing mouthful 16 input dechlorination pharmacy jars 17, open electrically-controlled valve 18, the dechlorination medicament flows into Sewage outlet 22 from chemical feed pipe 19, reaches dechlorination and the purpose of qualified discharge.Whether qualified discharge can reflect from chlorine residue meter 15 residual chlorine amount, then needs to regulate the dechlorination pharmaceutical quantities until up to standard if exceed standard.After if device reaction is long-time, have dregs of a decoction precipitation in the agitation vat 2, can regularly open electrically-controlled valve 6, the residue flushing is disposed in the container for storing liquid 8.The pH value tester can on-line testing sewage acid-basicity, the operation conditions of regulation and control system at any time.
