Efficiently solve the recycling and utilization of medical wastewater treatment equipment in hospitals
Product Description
Select the process based on the size, nature, and discharge direction of the hospital's wastewater treatment. According to hospital classification, it is divided into infectious disease hospitals and comprehensive hospitals. The discharge direction of hospital sewage after treatment is divided into two categories: discharging into natural water bodies and discharging into urban sewage treatment plants through municipal sewers.
The process used for hospital sewage treatment must ensure that the treated effluent meets the standard. The three main processes used are: primary treatment to enhance treatment effectiveness, secondary treatment, and simple biochemical treatment.


The principle of process selection is:
1. Infectious disease hospitals must adopt secondary treatment and carry out pre disinfection treatment.
2. Hospitals at or above the county level that discharge treated effluent into natural water bodies must adopt secondary treatment.
3. Comprehensive hospitals that discharge treated effluent into urban sewers (downstream with secondary sewage treatment plants) recommend using secondary treatment, and for those using primary treatment processes, the treatment effect must be strengthened.
4. For small comprehensive hospitals in economically underdeveloped areas, simple biochemical treatment can be used as a transitional measure when conditions are not available, and then gradually achieve secondary treatment or primary treatment with enhanced treatment effects.

The biodegradability of medical wastewater is good, so the secondary treatment process of wastewater should adopt biochemical treatment methods. To reduce investment, lower operating costs, decrease sludge production, and enhance the system's ability to withstand impact loads, this plan adopts a biological contact oxidation process of "hydrolysis acidification+aerobic oxidation" for the biochemical treatment of domestic sewage.
The biological contact oxidation method is an improvement of the traditional activated sludge biochemical treatment method, and the biological packing material is a semi soft packing material on a fixed bed. Using semi soft fillers as attachment carriers for microorganisms. The organisms are evenly distributed on the biological packing, which avoids the phenomenon of uneven distribution of microorganisms. At the same time, the organisms adhere to the surface of the packing and do not flow with water. Due to the strong agitation of the rising airflow, the biofilm is constantly renewed, thereby improving the purification effect. The contact oxidation method has the advantages of short treatment time, small volume, good purification effect, good and stable effluent quality, no backflow or expansion of sludge, and low power consumption. Its main characteristics are:
(1) High volumetric load and strong resistance to impact load;
(2) Having the advantages of membrane method, with less residual sludge;
(3) It has the advantages of activated sludge process, supplemented by mechanical equipment for oxygen supply, high biological activity, and short sludge age;
(4) Can decompose substances that are difficult to decompose by other biological treatments;
(5) Easy to manage, eliminating drawbacks such as sludge flotation and expansion.
After biochemical treatment, except for some bacteria that settle with the sludge, most pathogenic bacteria such as Escherichia coli and fecal streptococcus still exist in the sewage and must be disinfected. At present, there are many disinfection methods applied in the field of sewage treatment, such as liquid chlorine method, ozone method, sodium hypochlorite method, and chlorine dioxide method.
