Hydrolytic oxidization processing system for high-concentration medical waste water

Abstract

The invention relates to a hydrolytic oxidization processing system for high-concentration medical waste water, which comprises a closed water collecting pond, a closed sterilizing pond, a disinfectant removing pond, a hydrolytic pond, an activated sludge biological oxidization pond and a secondary sedimentation pond which are connected in sequence; the inside of a water inlet pipe of the closed water collecting pond is provided with a pipe type wet grinder; the closed water collecting pond and the closed sterilizing pond are in closed connection by a pipe; the bottom of the disinfectant removing pond is provided with an aerator, or the top of the disinfectant removing pond is provided with a balling gun of disinfectant neutralizing preparation; a water inlet of the hydrolytic pond is positioned on the lower part, and a water outlet is arranged on the upper part; a water inlet and a water outlet of the activated sludge biological oxidization pond are both positioned on the upper part, and a plurality of vertical baffle plates are arranged in the middle part; and a water outlet of the secondary sedimentation pond is connected with a water reservoir. The system has the advantages of good biological safety, unsusceptible occurrence of spreading risk of pathogenic microorganisms, the suitability for the processing of the high-concentration waste water, good purification effect, high purification degree of discharged water, relatively less investment, and convenient operation and maintenance.

Description

technical field [0001] The invention relates to a hydrolysis and oxidation treatment system for high-concentration medical wastewater, which belongs to the technical field of environmental protection. Background technique [0002] Medical sewage comes from hospitals and other medical institutions, which may contain a large number of pathogenic microorganisms, and contain various drugs, washing powder, soda ash, radioisotopes, cotton swabs, gauze, etc., and its COD is close to the numerical range of domestic sewage, but the fluctuation is relatively large. Large. The BOD / COD of sewage is generally around 0.5, and the biodegradability is good, but biological safety is an important issue, and it cannot be treated like ordinary sewage. [0003] According to the characteristics of medical sewage water quality and the adopted discharge standards, the current commonly used treatment technology is to pass the sewage through the grid and regulating tank into the aerobic biological tr...

AI Technical Summary

Problems solved by technology

The current ubiquitous defects are mainly manifested in several aspects: (1) Open tanks are mostly used, especially for aerobic biochemical treatment, because aeration is required in it, there will be a large amount of other discharges, and the gas in these gases The sol will carry microorganisms and diffuse into the atmosphere, and the sewage treatment plant itself is a source of pollution

(2) The operation is not standardized, and the degree of automatic detection and control is low. (3) Some processing sites occupy a large area and high operating costs

[0004] In view of this, people began to develop a fully enclosed treatment system, which closed all treatment equipment, and sterilized the purified water discharged from it and the collected air to achieve the purpose of eliminating biological harmlessness. Closed equipment requires relatively high investment and is difficult to operate and maintain
