Integrated street hospital sewage treatment and door-to-door delivery

Integrated street hospital sewage treatment and door-to-door deliveryThe hospital wastewater treatment equipment adopts the biological treatment process of * *. Based on the summary of the operating experience of domestic and foreign domestic wastewater treatment devices, combined with our own scientific research achievements and engineering practice, we have designed a complete set of * * wastewater treatment devices that can be buried underground. It integrates the removal of BOD5, COD, and NH3-N, and has the advantages of stable and reliable technical performance, good treatment effect, low investment, automated operation, convenient maintenance and operation, no surface area occupation, no need for building, no need for heating and insulation, etc. Flowers and grass can be planted on the ground without affecting the surrounding environment. Ordinary wards and other domestic sewage are usually treated by septic tanks first; The wastewater from sexual disease outpatient and ward departments should be collected and treated separately; The wastewater from the kitchen staff canteen should be treated with oil separation equipment; Wastewater should be collected and treated separately (through decay tanks), etc. Disinfection and sterilization treatmentIntegrated street hospital sewage treatment and door-to-door deliveryThe disinfection and sterilization process is the final step in wastewater treatment, and the key is to eliminate pathogenic microorganisms and fecal coliforms in the wastewater to meet the requirements of direct discharge standards. The key disinfection and sterilization methods include sodium hypochlorite, ozone, ultraviolet radiation, chlorine dioxide, and several others. The wastewater discharged by the hospital also contains a large amount of * * solutions, disinfectants, and other chemical drugs used internally in the hospital. It is necessary to collect and treat these toxic and harmful wastewater containing pollutants, and they cannot be discharged arbitrarily. The washing wastewater mainly comes from the printing of radiology photos, and the pollutants contained in it are mainly developer, fixative, and bleach. In addition, it also contains silver from the fixing solution, which can be recycled. The methods for recovering silver include electrolytic silver extraction and chemical precipitation. Low concentration silver containing wastewater can also be treated using ion exchange and activated carbon adsorption methods. Hospital wastewater contains a large amount of pathogenic microorganisms, viruses, and chemical agents. It has characteristics such as spatial pollution, acute and latent. Virus wastewater can be treated using disinfectants and ultraviolet light irradiation methods. Equipment installation: Buried or above ground, provide equipment foundation (concrete foundation) according to our company's equipment layout plan and equipment foundation diagram, with an average bearing capacity of 5000Kg/m2 or above; The foundation must be level and the relative elevation must be accurate. During earthwork construction, the width must be at least 500mm away from the foundation boundary to facilitate the installation of equipment and pipelines; When using a crane to position the equipment, it is necessary to clarify the direction and position of each individual unit in order to correctly and conveniently connect the pipelines; After connecting the pipeline, first conduct a pressure test with clean water to confirm that there is no water leakage in the pipeline connection. At the same time, adjust the levelness and outlet height of the sedimentation tank's effluent weir plate. Check the forward and reverse rotation of each motor equipment; Check the overall equipment. After confirming the installation is correct, backfill the soil and prepare for debugging.
