Embodiment
A kind of small-sized medical apparatus for treating sewage that present embodiment provides, structure is as shown in Figure 1, comprises filtering basin 1, settling tank 2 and ozonateur, is provided with filtering membrane in the filtering basin, is provided with ozonizer 3 in the ozonateur.The sewage outlet 5 of filtering basin 1 is connected with the sewage import 6 of settling tank 2, and the sewage inlet 4 of filtering basin 1 is low water inlet, and sewage inlet 4 is arranged on the bottom of filtering basin 1, filters the top that back sewage outlet 5 is arranged on filtering basin 1.Because many medical equipment water outlets are low, discharge is little, so low water inlet design is adopted in the sewage water filtration pond, is applicable to the sewage of collecting various medical facilities.Be provided with submersible pump 8 in the filtering basin 1, filtering basin 1 are connected with settling tank 2 through submersible pump 8.Submersible pump 8 is provided with vacuum breaker 9 with the connecting tube of settling tank 2, can prevent the sewage backflow in the settling tank through vacuum breaker.Be provided with liquid level sensor in the filtering basin 1, liquid level sensor is connected with submersible pump, can realize the automatic draining after liquid level reaches drainage requirement through liquid level sensor.
The sewage import 6 of settling tank 2 is arranged on the top of settling tank 2, and the water outlet 7 of settling tank 2 is arranged on the bottom of settling tank 2, and water outlet 7 is for handling the outlet of back sewage, and the ozone outlet of ozonizer 3 is connected in the ozone import that is positioned at settling tank 2 bottoms.
Filter through filtering basin 1 filtering membrane, about 99% suspended substance and metallic particles can be by filterings; Carry out primary reinforcement through 2 pairs of hospital sewages of settling tank and handle, reduce the Pollutant levels in the water, reach emission standard, can ensure sterilisation effect; Kill the various pathogenic bacterium in the sewage through ozonateur again, thereby make medical sewage reach emission request.
About the sewage water filtration pond is main is the solid dirt in the filtering sewage, regulating pondage, and lifting sewage gets into settling tank, so that subsequent disposal.Because many medical equipment water outlets are low, discharge is little, so low water inlet design is adopted in the sewage water filtration pond, is applicable to the sewage of collecting various medical facilities.Sewage gets into filtering basin and at first passes through the high efficiency filter membrane filtration, and about 99% suspended substance and metallic particles can be by filterings.Sewage through collection reach a certain amount of after, get into settling tank by the submersible pump lifting sewage.The sewage water filtration pond has liquid level sensor and output vacuum breaker, draining automatically.
Settling tank adopts the integrated vertical sedimentation basin of steelwork, and through settling tank hospital sewage is carried out primary reinforcement and handle, mainly be the Pollutant levels that reduce in the water, reach emission standard; Can ensure sterilisation effect on the other hand.
Ozonateur is the important process process of Hospital Sewage Treatment, and purpose is the various pathogenic bacterium of killing in the sewage.Ozone density at normal temperatures is 1.68; Ozone has been Duoed an active Sauerstoffatom than oxygen molecule, is a kind of strong oxidizer, is universally acknowledged broad-spectrum high efficacy disinfection sanitizer; But kill vegetative forms of bacteria and brood cell, virus, fungi etc., and can destroy Toxins, botulin.Its mechanism is to utilize the cytolemma of ozone layer destroying and oxidizing microorganisms, tenuigenin, enzyme system and nucleic acid, thereby makes bacterium and virus deactivation rapidly.Ozonization has no poisonous residual, can not form secondary pollution, is described as " oxygenant and the sterilizing agent that clean most ".The ozone preparation method has corona discharge method, ultraviolet method, chemical method and radiation method etc., and this patent adopts corona discharge method, and the chemical equation of its reaction is 3O
2==2O
