I. Dental clinic sewage discharge standards:
In accordance with the June 1, 1983 China's Economic Commission and the State Ministry of Health approved the trial implementation of hospital sewage discharge standards, the clinic's sewage treatment and disinfection should meet the following standards.
1. A sample of 500 ml of each of three consecutive times shall be tested and no intestinal pathogenic bacteria and tubercle bacilli shall be detected.
2. The total coliform count shall not be greater than 500 per liter.
3. Total residual chlorine amount of 4 ~ 5mg / L.
4. Sewage and chlorine contact time of not less than 1 hour.
II. Sewage treatment and disinfection design requirements:
Oral clinic scale is often not very large, the amount of sewage is also limited, and thus in the design of sewage treatment generally only need to create a sewage treatment tank can be. All medical sewage in the clinic must be imported into the treatment tank through a special pipe for disinfection before discharge. The design of the sewage treatment tank must meet the following requirements:
1. It should be far away from the treatment area and reception area, designed in a more secluded place.
2. There are anti-corrosion, anti-leakage facilities. Generally made of 1-centimeter-thick high-strength milamine board.
3. Ensure that the treatment effect, safety and durability.
4. Convenient operation, easy to disinfect and clean things, and is conducive to the operator's labor protection.
Three. Clinic sewage disinfection treatment methods:
Dental clinic small sewage treatment tank is generally used to quantify the capacity of the bleach put disinfection method, the current use of the most for the second time every day to put bleach tablets, according to the size of the treatment tank capacity of each put 10 to 20 pieces
Fourth. Sewage treatment tank style design:
Note:
1. Near the inlet hole of the first baffle must have a stainless steel filter, to prevent debris from entering the solenoid valve, affecting the use of the valve.
2. Timing the solenoid valve door automatically opens every hour to drain, to ensure that the sewage can have enough contact time with chlorine.
3. In order to prevent a sudden increase in water flow caused by sewage overflow sewage treatment tank, can be made at the top of the pool an overflow.
4. Dosing pool must be regularly removed sediment
This is the previous design requirements of the sewage treatment tank. Currently to eliminate this treatment method.
Now commonly used sewage treatment system equipment, it is convenient, fast, can meet the health standards.
