Process flow of hospital sewage treatment

Characteristics of JHDM integrated buried hospital sewage treatment equipment:

1. This device is capable of treating comprehensive wastewater from domestic systems and similar organic wastewater.

2. The secondary biological contact oxidation treatment process of the equipment adopts the contact oxidation process, which has a smaller volume than activated sludge, good adaptability to water quality, stable effluent quality, and no sludge swelling.

3. The equipment can be buried below the ground surface, which can be used as green or square land. Therefore, the equipment does not occupy the surface area, does not require building, and does not require heating and insulation.

4. The complete set of equipment is simple to construct and easy to operate. All mechanical equipment is automatically controlled, and all devices are located underground.

5. The entire processing equipment generally does not require dedicated management, only timely maintenance and upkeep of the equipment.

6. No need to compress the container. Equipment such as air compressors and circulation pumps greatly reduce investment costs.

7. Low required power, minimal maintenance and manual operation.

8. If the device is used in cold regions, the inspection hole can be raised to bury the device under frozen soil.

9. The integrated buried domestic sewage treatment equipment consists of two levels of tanks. The first level is a reinforced concrete structure with a larger burial depth, and the other group is a steel structure with a shallower burial depth. The steel structure pool adopts the domestically pioneered interpenetrating network anti-corrosion coating for corrosion prevention. It is an interpenetrating polymer formed by the interpenetrating of a rubber network and a plastic network. It is resistant to acid, alkali, salt, gasoline, kerosene, aging, abrasion, and rust. After applying the coating, the anti-corrosion life of the equipment can generally reach more than 15 years.
