The design scope includes the entire treatment process design of the sewage treatment project, including direct engineering such as equipment selection and installation, as well as indirect engineering such as design, commissioning, and training of this project; But it does not include auxiliary projects such as civil engineering construction, external power supply, water diversion, drainage and greening, roads, etc., nor does it temporarily consider auxiliary projects such as communication, transportation, power supply and distribution, heating, etc. for sewage treatment stations.

Design concept

In the design of the hospital sewage treatment system, the principles of technical applicability, targeted process measures, reliable and stable system, easy to start and stop operation, comprehensive cost saving of one-time investment and daily operation, maximum reduction of site occupation area, and maximum use of existing treatment facilities are adhered to; Through comprehensive analysis of similar sewage treatment technologies at home and abroad, especially the practical experience of the same project, a sewage treatment process combining "hydrolysis acidification+contact oxidation method" and "chlorine dioxide disinfection method" has been formed. Firstly, a self-made grid is used to remove large impurities and floating debris from the sewage. Then, after being regulated by a regulating tank, the sewage is discharged into the hydrolysis acidification tank and the contact oxidation tank in sequence. After biochemical treatment, the sewage is settled in the sedimentation tank and disinfected with chlorine dioxide to meet the standard before being discharged.

A regulating tank is a structure used to regulate the inflow and outflow flow rates, mainly playing a role in regulating water quantity and quality, as well as pre aeration regulation of sewage pH value and water temperature.

The new model is easy to operate, flexible to move, and convenient for medical staff to push and reduce labor intensity; After multiple filters and reactions, medical wastewater can be effectively purified before being discharged, protecting the environment and reducing the spread of bacteria.

In the nursing department of a hospital, medical staff generate a large amount of medical wastewater during the process of dressing and cleaning patients. Due to the lack of wastewater discharge and collection devices in the ward, medical wastewater cannot be collected or effectively treated, which increases the difficulty of medical staff's work and also affects their work efficiency. Direct discharge of medical wastewater into sewers not only causes waste of water resources, but also easily pollutes the environment. Therefore, for the medical wastewater generated during the nursing process, there is a need for a device that is convenient for medical staff to move, reduces labor intensity, and can effectively collect, filter, and purify wastewater to meet the needs of hospital nursing. It is also necessary to avoid the problem of device blockage caused by long-term use and reduce maintenance costs.

Preventing and controlling medical wastewater pollution is the primary goal of medical wastewater prevention and control. Specifically, it is necessary to ensure that the discharge of medical wastewater meets the national standards. The "Water Pollution Discharge Limits (Daily Average) for Comprehensive Medical Institutions and Other Medical Institutions" in the 2005 Chinese medical institution water pollutant discharge standards (GB18466-2005) stipulate that: (1) intestinal pathogenic bacteria and intestinal viruses shall not be detected. (2) The number of fecal coliforms should not exceed 500 per liter. (3) Total residual chlorine (disinfection process using chlorine containing disinfectants): shall not exceed 0.5mg/L (emission standard: disinfection contact tank contact time ≥ 1h, total residual chlorine in contact tank 3-10mg/L)

Hospital sewage refers to the sewage discharged from hospitals (general hospitals, specialized hospitals, township health centers, infectious disease hospitals and other types of hospitals, blood stations, disease control centers, community health service centers) into the natural environment or urban pipelines. The water quality varies depending on the nature, scale, and location of different hospitals.

The equipment separates solid impurities and water from solid medical wastewater, and effectively disinfects the medical wastewater through ultraviolet disinfection, high and low temperature disinfection, and disinfectant disinfection. The wastewater treated by this medical wastewater treatment device can be directly discharged without causing pollution to the environment, and is suitable for use in various hospitals and clinics.

equalization tank

This pool is a structure used for regulating and homogenizing sewage volume Due to the unevenness of the discharge period of domestic sewage, the coefficient of variation is relatively large, that is, the discharge volume is large in one period and small in another period. In order to ensure the balanced operation of the biochemical treatment system and minimize the impact of its shock load to achieve the ideal treatment effect, it is necessary to set up a regulating tank to adjust and homogenize the inflow of sewage, so that the regulating tank sewage lift pump always supplies water to the biochemical system according to the average treatment water volume. According to data statistics, the effective volume of the regulating pool is calculated based on 6-8 times the average hourly processing capacity.

A regulating tank for medical wastewater treatment, comprising a protective cover body, a first insulation layer, a fixed groove, a regulating tank body, a controller, a rotating shaft, and a groove. The bottom of the protective cover body is equipped with a battery pack, and a hydraulic cylinder is installed below the protective cover body. A hydraulic rod is installed above the hydraulic cylinder, and the fixed groove is opened above the left and right body walls of the protective cover body. The regulating tank body is fixed on a support plate, and the controller is installed on the right body wall of the regulating tank body. A temperature sensor is installed above the controller, and the rotating shaft is set on the left and right sides of the regulating tank body. The outer side of the rotating shaft is flexibly connected to a fixed plate, and the groove is opened below the rotating shaft. The regulating tank for medical wastewater treatment is electrically connected between the heating wire, controller, and temperature sensor, It can automatically monitor the temperature inside the regulating pool and promptly raise the temperature.
