Generally, waste liquid can be discharged after acid-base neutralization, coagulation precipitation, and sodium hypochlorite oxidation treatment. Organic solvent waste liquid should be treated according to its nature. Recycle. Acid and alkali waste liquids should be properly concentrated and neutralized with sodium hydroxide or sulfuric acid until they are nearly neutral, then diluted with water and discharged; waste liquids containing cyanide should be treated separately, and bleaching powder should be added under alkaline conditions to decompose them before being cleaned and discharged; Prepare the "Three Wastes Treatment Record Form". 4.4.3 Waste gas treatment: General toxic gases can be discharged through fume hoods or ventilation ducts and diluted with air. For example, sample digestion, extraction and other processes will produce toxic and harmful gases, which should be carried out in a fume hood; toxic and harmful gases generated during the analysis of instruments such as atomic absorption meters and atomic fluorescence photometers should be pumped outdoors for dilution and discharge. A large amount of toxic gases must be fully burned with oxygen or absorbed before they can be discharged. 4.4.4 Treatment of biological waste: Biological waste should be selected in appropriate containers and locations according to its characteristics, collected by dedicated personnel for classification, disinfection and burning, and disposed of on a daily basis.
