In order to further standardize and guide medical sewage treatment, the national environmental protection department sets up technical standards for hospital sewage treatment in 2013 (HJ 2029-; in this specification: the first-class strengthening process is recommended to be adopted for the non-infectious disease hospital sewage discharged into the urban sewer.
The first-stage strengthening process flow comprises the following steps:
at present, most of hospital drainage terminals in China are built with urban sewage treatment plants, sewage discharged into a sewer is subjected to a pretreatment standard, if a primary strengthening process is adopted to treat medical sewage, grid slag and coagulating sedimentation sludge are generated every day, further treatment and disposal are needed, and the cost of the treated manpower and material resources is high. Moreover, each hospital has a plurality of buildings, generally speaking, each building of the medical buildings is provided with a septic tank, and sewage in the septic tank is collected to a sewage treatment station of the hospital for primary strengthening treatment. In the treatment mode, the sewage can reach the discharge standard, but the sludge treatment obviously has some problems; if a hospital has a plurality of septic tanks and a centralized sewage treatment station, and all the septic tanks and the centralized sewage treatment station are provided with a first-level strengthening process for treating medical sewage and sludge, the cost of manpower and material resources is high; if only the medical sewage and the sludge which are converged to the sewage treatment station are subjected to primary strengthening treatment, the sludge of the septic tank of a single medical unit is not treated, and the sludge danger generated by the septic tank matched with the medical building is higher in fact.
The utility model has the following contents:
the utility model discloses, be exactly to the difficult point of above medical sewage's processing and sludge treatment, adopt the technology that subregion processing and centralized processing combined together with these medical sewage and sludge, make medical sewage and sludge treatment system perfect, simple and effective more to reduce the treatment cost of medical sewage and sludge, improve the treatment effect of medical sewage and sludge, so that relevant departments will refer to when revising hospital sewage treatment technical specification in future; meanwhile, an alternative and reference method is provided for the current medical sewage and sludge treatment.
The block treatment system for medical sewage and sludge comprises an A block and a B block, wherein the A block is a sewage and sludge treatment block of each medical unit, and the B block is a sewage and sludge centralized treatment block formed by the collected sewage of the A block.
According to the block treatment system for medical sewage and sludge, the A block and the B block are respectively composed of corresponding sewage treatment facilities and matched sludge pools.
A medical sewage and sludge block treatment system, each medical unit is matched with an A block treatment facility, sewage is treated by multistage anaerobic precipitation in the A block sewage treatment facility, and then discharged into a B block for further treatment and discharge after reaching the standard; and when the sewage treatment facilities of the block A and the sewage treatment facilities of the block B run to the design period of sludge clearing, the sludge is pumped into sludge bags of sludge pools matched with the block A and the block B for filtering, anaerobic treatment, drying and disinfection treatment.
A blocking treatment system for medical sewage and sludge is characterized in that a sludge tank is a sludge treatment facility matched with an A block or a B block, and the sludge tank comprises a sludge tank wall, a filter layer, a sludge bag, a sludge pump, a sludge input pipe, a filtrate pump, a filtrate return pipe, a dosing pipe and a sludge tank well cover; the filter layer is arranged at the position 0.5-1.5m high on the bottom of the sludge tank; the sludge bag is arranged on the filter layer and is made of a material with a mesh aperture of 0.5-2 mm; the sludge tank and the sewage treatment facilities of the A block and the B block form a whole, and a vent pipe, a sludge pump, a sludge input pipe, a filtrate pump and a filtrate return pipe are arranged between the sludge tank and the sewage treatment facilities of the A block and the B block; the sewage treatment facilities of the A block and the B block deposit sludge, when the design period of sludge cleaning is reached, sludge is directly pumped into a sludge bag of a sludge pool by a sludge pump through a sludge input pipe for filtering or drying, filtrate is pumped into the sewage treatment facilities by a filtrate pump for treatment with sewage, sludge in the sludge bag is subjected to long-time anaerobic treatment, a disinfectant is added through a drug adding pipe, and the sludge is sterilized and dried for a long time and finally lifted out for cleaning after the test reaches the standard;
a block treatment system for medical sewage and sludge is characterized in that the sludge cleaning design period of a sewage treatment facility is 3-5 years;
a block treatment system for medical sewage and sludge, wherein a municipal sewage treatment plant is built at a drainage terminal, and only one small hospital of a medical building can be used for the medical sewage and sludge treatment by adopting B block treatment.
A block treatment system for medical sewage and sludge is characterized in that the sewage of medical units in hospitals, infectious departments, department of fire prevention and laboratories, needs to be pretreated according to relevant regulations and then enters the block treatment system for treatment.

Detailed Description
The embodiments of the present invention will be further explained with reference to the accompanying drawings:
as shown in figure 3, four buildings are provided in a hospital, namely an outpatient service building, a hospitalized building, an infectious department and a functional laboratory department, the block treatment system for medical sewage and sludge is used for treating the medical sewage and sludge, four A block treatment facilities and a B block treatment facility are correspondingly matched, and sewage is primarily treated in the A block and then is uniformly collected in the B block to be treated and reach the standard, and then is discharged into a city sewer.
As shown in figures 1 and 2, in the medical sewage and sludge blocking treatment system, sludge generated in the operation process of a sewage treatment facility (1) of a block A and a block B is deposited in the sewage treatment facility (1), when the sewage treatment facility (1) reaches a designed sludge clearing period, a sludge pump (8) is used for pumping into a sludge bag (12) in a sludge tank (2) through a sludge input pipe (9) for filtering or drying, filtrate is pumped back into the sewage treatment facility (1) through a filtrate pump (4) for treatment with sewage, sludge (13) in the sludge bag (12) is subjected to long-time anaerobic treatment, a disinfectant is added through a medicine adding pipe (6) for sterilizing and drying for a long time, and finally the sludge bag filled with the sludge is lifted out for clearing treatment after the inspection reaches the standard;
the sludge cleaning period of the sewage treatment facility is designed to be 3 years, and the periods of filtering, anaerobic treatment, drying and disinfection of sludge in a sludge bag of a sludge tank are also set to be 3 years. That is to say: according to the medical sludge produced in the hospital medical sewage treatment process, if the medical sludge is treated according to the traditional sewage and sludge treatment method, the grid slag and the coagulated sludge of 4 medical units and sewage treatment stations are required to be cleaned, filtered, dried, disinfected and cleared, and the sludge produced by the operation of the sewage treatment main facilities of the block A and the block B in the embodiment is only required to be treated and disposed once in 3 years, so that the labor cost and the expense for sludge treatment and disposal are greatly saved.
