1. Test department wastewater must be someone responsible for sewage treatment, test department generated wastewater without disinfection, can not be directly discharged into the sewer. .
2. The person concerned puts enough disinfectant tablets (depending on the available 1000 mg / L chlorine) in the waste bucket of the equipment according to the daily water output. Dispose of the effluent the next day and turn it back on.
3. The sewage will be stained by pouring it into a special plastic bucket and putting in disinfectant tablets (1000 mg / L depending on the available chlorine) according to the quantity and treating it the next day.
Principles of laboratory wastewater treatment:
1. Prevention of pollution: to prevent the discharge of infectious pathogens and environmental pollution. Strictly disinfect a variety of specimens that may discharge a large number of infectious agents and sewage contaminated by infectious agents, and only when the corresponding hospital wastewater discharge standards.
2. Sorting process: Wastewater containing specific chemical toxicants will be collected whenever possible. It will be treated separately. Prevent large quantities of toxic and hazardous substances from entering the integrated drainage system
3. Strict discharge: Wastewater containing radioactive substances must be collected separately and discharged into the integrated wastewater system only when it meets the discharge standards.
4, the implementation of standards: hospital integrated wastewater should be treated according to the direction of its effluent discharge and a variety of requirements, only to meet the appropriate discharge standards before discharge. Hospital wastewater discharged directly or indirectly into different water bodies is usually implemented according to the functional requirements of the incoming water to the first or second level of discharge standards, which requires secondary (biological) treatment. Except for hospital effluent containing pathogenic bacteria and certain specialized pollutants, hospital effluent in municipal wastewater is generally similar to household effluent and can be discharged without separate treatment to meet effluent standards. It can then be discharged.
5. Ensure safety: the inspection department for sewage disinfection disinfectant as safe and reliable as possible, easy to operate, low cost and high efficiency.
6. Strengthen management: water recycling can strengthen the water quality inspection department of water management to save water and reduce sewage discharge, can be used for water resources and poor conditions.
How to deal with laboratory wastewater:
1. Lead-containing waste liquid
Analytical methods of quantitative analysis using atomic absorption spectrometry.
Note that if more than two heavy metals are present, the optimal pH for treatment will be different, so please be careful with the treated wastewater. Waste liquids and complex ions containing large amounts of organic matter and cyanide must be decomposed and removed in advance.
2. In principle, waste liquids containing acids, bases and salts should be collected separately. However, if there is no problem, it can be neutralized or used in the treatment of other waste liquids. Before discharge, dilute the diluted solution with water to 1% or less. If it proves not dangerous to mix acidic and alkaline waste liquids, one can be added bit by bit to the other. Check with pH paper and set the pH of the mixed waste solution to about 7. Dilute with water to reduce the concentration to less than 5% and then discharge directly.
