Method for treating medical waste water

Abstract

The invention discloses a method for treating medical waste water. According to the technical scheme, the method includes the steps of sterilizing, anaerobic treating, precipitating and adsorbing. According to the method, as a chemical method, a biological method and a physical method are combined, pathogenic microorganisms, heavy metal ions and radioactive elements in the water are effectively removed, injuries to the human body and damage to the environment are reduced to the maximum degree, the removing rate is high, and cost is low; water hyacinths and typha orientalis are planted in an artificial wetland pool, heavy metal can be enriched and recycled, the environment can be further beautified, and air can be purified; the pH is adjusted through acetic acid and lime, and the price is low; due to the acetic acid, the sterilizing effect is achieved, the content of the acetic acid in the waste water can be increased, and the marsh gas amount can be increased; generated marsh gas can be used for cooking and illuminating of staff dining halls, and a large amount of coal, a large amount of electricity and a large amount of natural gas are saved; when yeast carries out adsorption, wine making residues are sufficiently used, waste is turned into wealth, waste fermentation mycelia are sufficiently used, and cost is saved; secondary pollution can be avoided, cost is low, the effect is remarkable, and the sustainable development view is achieved.

Description

technical field [0001] The invention relates to a sewage treatment method, in particular to a medical sewage treatment method. Background technique [0002] Medical institutions include hospitals, health centers, nursing homes, outpatient departments, clinics, first aid stations, etc. According to statistics, the current total number of medical institutions above the county level in my country (including industrial and mining enterprise hospitals, military hospitals, private hospitals and Sino-foreign joint venture hospitals, etc.) is about 21,000 Home. Relatively speaking, large-scale hospitals have certain wastewater treatment systems, but the construction of wastewater treatment systems in small-scale hospitals is relatively weak. Generally speaking, wastewater from most medical institutions in my country has not been treated well, and the sources and components of hospital sewage are complicated. Containing pathogenic microorganisms, toxic and harmful physical and chemi...
