C, precipitation process: contact-oxidation pool water outlet enters second pond and carries out solid-liquid separation, supernatant liquor after precipitation enters sterilization pool, adding CLO2 carries out disinfection, sewage self-flowing after sterilization enters dechlorination pond, add S-WAT and carry out dechlorination, finally by quartz filter, filter, water outlet is through standardization row mouthful qualified discharge;
(2) sludge treatment: second pond part sludge reflux is to hydrolysis acidification pool and contact-oxidation pool, excess sludge drains into sludge thickener and concentrates, sludge thickener supernatant liquor is back to equalizing tank, and concentrated rear mud is squeezed into chamber filter press by spiral pump and dewatered, and mud cake outward transport is disposed.
In described equalizing tank, establish diving mixer, by stirring action, sewage homogeneous in equalizing tank is all measured.
Aerating system aerator is under water set in described contact-oxidation pool.
Beneficial effect of the present invention: orthopedics and traumatology of Chinese medicine medical waste water treatment process of the present invention and device, for being rich in the pathogenic microorganisms such as excrement colibacillus group, viral waste water, the biochemical method with sterilizing in conjunction with processing of main employing, technique tool of the present invention has the following advantages:
1, less investment, technical process is the simplest.
2, can adapt to the organic sewage of different concns.
3, variation water quality is had to stronger shock resistance.
4, (HRT) is shorter the required residence time, and the clearances such as SS, BOD, COD and ammonia nitrogen are high.
5, operating performance is stable, produces surplus sludge volume few, has reduced working cost.
6, energy-efficient, dependable performance, operational management are convenient, for ease of maintenaince, do not produce secondary pollution.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in further detail.
Medical waste water water quality:
