summary:

The hospital wastewater treatment equipment adopts advanced biological treatment technology. 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 organic 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 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.

Hospital wastewater contains some special pollutants, such as disinfectants, diagnostic agents, detergents, as well as a large number of pathogenic microorganisms, parasite eggs, and various viruses.
In addition to various pathogens, viruses, and parasitic eggs, hospital wastewater also contains many inorganic and organic substances, such as various disinfectants, radioactive isotopes used for diagnosis, and so on. Therefore, in the treatment of hospital wastewater, it is necessary to consider both the hygiene indicators of disinfection and sterilization, as well as environmental indicators such as CODcr and BOD5.

Equipment features:

1. Buried below the surface, the surface above the equipment can be used for greening or other purposes, without the need for building houses, heating, or insulation.

2. The secondary biological contact oxidation treatment process adopts push flow biological contact oxidation, which has a better treatment effect than fully mixed or two-stage series fully mixed biological contact oxidation tanks. And it has a smaller volume than activated sludge tanks, strong adaptability to water quality, good shock load resistance, stable effluent quality, and will not cause sludge expansion. Adopting new methods in the poolType elastic three-dimensional filler, with a large specific surface area, is prone to biofilm formation and detachment by microorganisms. Under the same organic load conditions, it has a high removal rate of organic matter and can improve the solubility of oxygen in air in water.

3. The biochemical tank adopts the biological contact oxidation method, which has a relatively low volume load of the filling material, and the microorganisms are in their own oxidation stage, resulting in low sludge production. It only takes more than three months (90 days) to discharge the sludge (using fecal trucks to suction or dehydrate into sludge cakes for external transportation).

4. The deodorization method of this buried domestic sewage treatment equipment not only uses conventional high-altitude exhaust, but also includes soil deodorization measures.

5. The entire equipment processing system is equipped with a fully automatic electrical control system and equipment fault alarm system, which operates safely and reliably. Generally, there is no need for dedicated personnel to manage it, and only timely maintenance and upkeep of the equipment is required.
