With the continuous improvement of people's living standards, various diseases have gradually emerged, with tens of thousands of people participating in hospital activities every day. Taking a children's hospital as an example, the number of medical staff entering and leaving every day reaches 2000. The treatment of hospital sewage has become a major challenge for hospitals at present. The average daily sewage discharge capacity of children's hospitals reaches 300 cubic meters per hour. Therefore, specialized hospital sewage treatment equipment and hospital sewage disinfection equipment need to be equipped for treatment in order to achieve qualified discharge. If we do not pay attention to the treatment of hospital sewage, it may bring many unexpected problems. So, how does the equipment handle hospital sewage treatment problems? Today, we will briefly explain.

The hospital summarizes that the sewage first passes through the large floating objects in the grid, and the suspended objects are blocked by the grid. The grid needs to be regularly sorted, and there are two options for users to choose from: manual and active. After the sewage flows out of the grid tank, it enters the conditioning tank, which reduces the peak and homogenizes the water quality. Install a submersible sewage pump, a high sealing liquid level controller, and a submersible aerator in the conditioning tank. When the water level in the pool reaches the high level, the water pump actively starts working, and when the sewage in the pool reaches the low level, the system actively stops operating. The operation of the submersible aerator is controlled by a microcomputer timing controller, which is activated on time to pre-treat the water quality. After the sewage enters a section of biological touch oxidation tank from the conditioning tank, the aeration system starts to activate, and the sewage is subjected to biological treatment. The suspended filler in the tank can improve the treatment efficiency, and the treated sewage flows into the section of biological touch oxidation tank for further treatment. The treated sewage flows into the sedimentation tank by itself, which is equipped with inclined plate fillers to accelerate the separation of mud and water. After separation, clean water flows into the touch disinfection tank and an appropriate amount of chlorine dioxide disinfectant is actively added to the inlet. After touching the sewage for one hour, the disinfectant enters the dechlorination tank and actively participates in the dechlorination treatment at the inlet. In the tank, the dechlorination treatment is carried out before discharge. In order to ensure the activity of bacteria in the biochemical tank, the control of the aerator adopts dual circuit control. When the sewage station flows into the sewage, the operation is actively started.

After hospital sewage treatment, in order to meet the discharge standards in GBl8466-2005, it is necessary to choose a secondary sewage treatment process (i.e. biological treatment)+disinfection. If discharged to surface water bodies, hospitals also need to undergo dechlorination treatment. In the various processes of secondary sewage treatment, based on the existing structures in the hospital and the fact that the operators are mostly non professional technical personnel, it is advisable to choose a fully active two-stage biological touch oxidation process+disinfection+dechlorination. This process occupies a small area, produces less sludge, has good impact resistance, and is fully active in operation. To prevent noise, a submersible aerator is selected for aeration. In the two-stage biological touch oxidation process, the CODcr removal rate of the effluent from the secondary sedimentation tank can reach 85%, the BOD5 removal rate can reach 92.5%, and the SS removal rate can reach 90.9%, ensuring that the discharge standards can be met.

The treatment of hospital sewage is highly valued by the government in the Weifang region, and various hospitals have continuously purchased hospital sewage treatment equipment to address the discharge of hospital sewage. It is hoped that the treated sewage can be discharged in a standardized manner.
