No energy consumption medical sewage treatment unit
Technical field
The utility model relates to waste disposal plant, particularly a kind of no energy consumption medical sewage treatment unit.
Background technology
Now sewage carries out anaerobic biological and handles, sterilization and disinfection then, and this method is need not power, but sewage residence time in the pond is longer, is generally three days, so one-time investment is bigger.The sewage aerobic biochemical treatment, sterilization and disinfection then, this method needs power (electricity consumption) to carry out blast aeration, jet-flow aeration, so working cost is higher, running machinery will often keep in repair, and the personal management arranged.
Summary of the invention
The purpose of the utility model provides a kind of no energy consumption medical sewage treatment unit, and this device need not external energy, the WWT fully automated.
To achieve these goals; The technical scheme that the utility model is taked is: no energy consumption medical sewage treatment unit comprises the solid substance separator, biological bed, upflowing bacteria bed, metering pond, antisepsis contact tank, U trap, inverted cup, dispensing kit and the explosive box of taking place of upflowing; Skeuomorph separator, biological bed and the upflowing bacteria bed of taking place of upflowing; Be interconnected by two circulating tubes, the upflowing bacteria bed is communicated with the metering pond by cinclides, in the metering pond, U trap and inverted cup is arranged; Inverted cup is connected with dispensing kit with drug-feeding tube by the vacuum breaking pipe; The vacuum equilibration tube is communicated with the vacuum breaking pipe, and explosive box is communicated with dispensing kit through pencil, and U trap is communicated with antisepsis contact tank.
Vertical flow deflector is arranged in the solid substance separator, in the bed swash plate is arranged biological generation of upflowing, porous plate and packing course are arranged in the upflowing bacteria bed, training wall is arranged in antisepsis contact tank, fluid level controller is installed in crossing on the pencil in dispensing kit.
The beneficial effect of the utility model: need not external energy, the WWT fully automated.Take up an area of few, secondary property less investment, working cost is low, need not the personal management, total system just can turn round automatically.

Embodiment
As shown in Figure 1, sewage at first gets into solid substance separator 1, and flow deflector 2 is arranged in separator; The solid substance of suspension is floated in the left side of flow deflector 2, and proportion is sunken to the bottom greater than the solid substance of water, and more clear water is introduced biological bed 3 bottoms that take place of upflowing through circulating tube 4; In the bed 3 swash plate 5 is arranged biological generation of upflowing, because the effect of swash plate 5 makes mud be sunken to the bottom; Clear water upwards flows and carries out a biological disposal upon, and to reduce BOD, the COD in the sewage, gets into 6 ends of upflowing bacteria bed through the water of carrying out a biological disposal upon through circulating tube 8; Water passes porous plate 7 and packing course 21 from the bottom to top successively, plays a role in filtering on the one hand, plays the biological bed effect that takes place simultaneously; Packing course has big adsorption, forms microbial film on the packing course surface, and BOD, the COD of water had bigger clearance; Water after above second-stage treatment flows into metering pond 9, in metering pond 9, U trap 12 and inverted cup 13 is arranged, and is communicated with by the top 22 of vacuum breaking pipe 15 and drug-feeding tube 16 and dispensing kit 20; On vacuum breaking pipe 15, connect vacuum breaking equilibration tube 14, explosive box 17 is communicated with dispensing kit 20 by crossing pencil 19.
When liquid level reaches a certain height in the metering pond 9; U trap L (12) begins siphon, and drug-feeding tube 16 produces vacuum, thereby sterilizing agent flow in the inverted cup 13 from dispensing kit 20; Sterilizing agent mixes the back with sewage and gets into disinfecting tank 10 in U trap 12; By the effect of training wall 11, make sewage after disinfecting tank 10 stops certain hours, after being killed, intestinal bacteria in the water efflux.
When the liquid level in the metering pond 9 was reduced to a certain position, vacuum breaking equilibration tube 14 got into air, and air gets into vacuum breaking pipe 15 and drug-feeding tube 16 again, and dispensing is stopped; Air admission inverted cup 13 makes sewage stop siphon.
When dispensing kit 20 began to offer medicine, liquid level began to descend in the case, and fluid level controller 18 work make thimerosal flow into dispensing kit 20 from explosive box 17 through pencil 19; When dispensing kit 20 liquid levels rose to a certain height, fluid level controller 18 work made that sterilizing agent stops to flow in the dispensing kit 20 in the explosive box 17.
