Abstract
The invention relates to a recyclable medical wastewater treatment method, belonging to the technical fields of environmental protection, special industrial wastewater treatment and the like. The recyclable medical wastewater treatment method is characterized by comprising pre-treatment, anaerobic and bioflocculation treatment, aerobic treatment, macromolecular flocculation treatment, MBR (Membrane Biological Reactor) treatment and disinfecting and recycling treatment. Due to the adoption of the technical scheme, the medical wastewater with poor biodegradability can be treated with high efficiency, one-time biological backflow flocculation treatment, one-time macromolecular flocculation treatment and MBR membrane type reaction are implemented, a sludge reduction effect is obtained, a defect of immediately discharging the wastewater after disinfection in an original treatment method is also made up, the disinfected wastewater can be recovered for flushing a toilet, the purposes of treating and recycling the wastewater and saving water resources are achieved, and the treatment method is energy-saving and efficient.
Description
Technical fieldBut the present invention relates to a kind of medical waste water treatment process of reuse, belong to technical fields such as environment protection, special industry wastewater treatment.
Background technologyMedical waste water mainly is the sewage of discharging such as consulting room, laboratory, ward, laundry, X sheet photo studio and the Operation theatre from hospital, and its sewage source and composition are very complicated, and the water quality homogeneity is poor, and mixes the malignant bacteria, virus etc. of some amount.To medical waste water; Existing treatment process has activated sludge process, biological contact oxidation process, BAF method, biomembrance process etc., for the good waste water of biodegradability certain effect is arranged, and has the shortcoming of active sludge operation stability difference simultaneously; For the relatively poor medical waste water DeGrain of biodegradability; A lot of township hospital only rest on simply to sterilize and promptly carry out discharge phase, have very big hidden danger and environment has been caused certain pollution, have caused the waste at water source simultaneously.
Summary of the inventionThe present invention is in order to remedy above-mentioned technological deficiency, to reflux through a secondary pollutant to the bad medical waste water of biodegradability and flocculate a flocculating polymer processing; In conjunction be separated into main treatment process with MBR; A kind of treatment process of efficient energy-saving is provided, and the recyclable usefulness of flushing the toilet of the waste water after the sterilization can reach treatment effect; Can reach wastewater reuse again, play the purpose of practicing thrift the water source.
To achieve these goals, technical scheme of the present invention is: but a kind of medical waste water treatment process of reuse is characterized in that pre-treatment-anaerobism and biofloculation processing-aerobic treatment-flocculating polymer processing-MBR reactor for treatment-sterilization recycling.
Its concrete steps are following:
(1) through grid filtration with catchment, removing the solid pollutant in the waste water, and, reach water-quality ratio purpose uniformly with the wastewater collection that different time sections is discharged;
(2) waste water gets into anaerobic pond through lift pump, in anaerobic pond, carries out anaerobic acidification, utilizes the anaerobion degradation of organic substances;
(3) adopt aerating system that the waste water that pumps into Aerobic Pond is carried out aeration, dissolved oxygen is more than 3mg/L;
(4) regulating the pH value is 7.5-8.5, and waste water per ton adds the 20-80g Poly aluminum Chloride (PAC);
(5) with purification type ultrafiltration membrane system with active sludge, throw out, and thalline etc. hold back;
(6) carry out reuse behind the employing disinfection by chlorine dioxide.
In described anaerobism and biofloculation processing and aerobic treatment; When sludge quantity is too much; The excess sludge that the anaerobic and aerobic process is produced pumps into and dissolves in born of the same parents' reactor drum, and sludge concentration is controlled at 50-100g/L, adopts ultrasonic disruption; Supernatant is back to anaerobic reactor, carries out biology backflow flocculation.
Beneficial effect of the present invention is: can efficiently handle to the medical waste water of biodegradability difference; Realize secondary pollutant backflow flocculation, a flocculating polymer processing and MBR film type reaction, not only played the effect of mud decrement, also remedied the defective of discharging immediately behind the sterilisation stage in original treatment process; The waste water quality of handling after sterilizing is good; The recyclable usefulness of flushing the toilet can reach treatment effect, can reach wastewater reuse again; Practicing thrift the purpose at water source, is a kind of treatment process of efficient energy-saving.
