NOVELTY - Medical wastewater treatment method includes filtering wastewater, adjusting pH, UV-irradiating, and anaerobically fermenting; filtering, adjusting pH with lime, adding polyacrylamide, stirring, standing, and filtering; flowing into artificial wetland pond planted with water hyacinth and cattails, filtering, flowing into microbial pool, adjusting pH with acetic acid, absorbing with yeast, and filtering; flowing into disinfection pool, adjusting pH with lime, and performing ozone disinfection; and performing adsorption of medical stone, filtering, and discharging.    USE - Method for medical wastewater treatment (claimed).    ADVANTAGE - The method is combination of chemical, biological and physical method, increases content of acetic acid in water and amount of biogas generated which can be used for cooking and lightning saving a lot of coal, turns waste into treasure by using wine residue as yeast which saves cost and fully utilizes waste fermentation bacteria, and has high removal rate of pathogenic microorganisms, heavy metal ions and radioactive elements in water, low cost, environment beautifying and air purifying effects, and bactericidal effect by using acetic acid.    DETAILED DESCRIPTION - Medical wastewater treatment method comprises:    (A) filtering wastewater through 4 mesh stainless steel filter, adding into centralized sewage collection tank, adjusting pH to 6-8, and UV-irradiating at dosage of 30-50 mJ/cm2 for 20 minutes;    (B) adding into sewage digester, and anaerobically fermenting;    (C) discharging digester effluent into 10 mesh stainless steel filter, filtering, adding into flow sedimentation tank, adjusting pH to 9-11 with lime, adding 0.1-0.3 wt.% polyacrylamide, stirring, standing for 1-2 hours, and filtering through 80 mesh stainless steel filter;    (D) flowing into artificial wetland pond planted with 8-10 strains/m2 water hyacinth and cattails, and filtering effluent through 100 mesh stainless steel filter;    (E) flowing into microbial pool, adjusting pH to 3-5 with acetic acid, absorbing with yeast for 6-8 hours, and filtering through 100 mesh stainless steel filter;    (F) flowing into disinfection pool, adjusting pH to 6.5-7.5 with lime, and performing ozone disinfection at ozone concentration of 10-15 mg/L for 15-20 minutes; and    (G) performing adsorption of medical stone, filtering through 10 mu m nonwoven filter, and discharging.
