生活饮用水化学处理剂在规定的投加量使用时，处理后水的一般感官指标应符合

Drinking water chemical treatment when the dosage prescribed use, general post-processing sensory indicators of the water should meet the requirements of "drinking water health standards" (2001). Wherein, when the chemical treatment agent into the drinking water in the drinking water is harmful substances "drinking water quality standard" predetermined material (2001), the allowable limit of the material was 10% corresponding to a predetermined limit. Comprises a metal arsenic, cadmium, chromium, lead, silver, selenium, and mercury (Hg limit of 0.0002mg / L) depends on the product both inorganic and organic materials, formulation and manufacturing process. For radioactive material, mineral-based products should determine total radioactivity α and β total radioactivity used directly. However, when the chemical treatment agent into the drinking water in the drinking water of harmful substances in the "drinking water quality standard" (2001) are not specified, it may be determined with reference to domestic and international standards, which is the permissible limit for the allowable concentration 10%.

When the chemical treatment agent for drinking water is used in the prescribed amount, the general sensory index of treated water shall conform to the requirements of the Sanitary Code for The Quality of Drinking Water (2001). Among them, when the chemical treatment agent for drinking water into drinking water harmful substances are the "living drinking water quality hygiene norms" (2001) specified in the substance, the permissible limit of the substance is 10% of the corresponding prescribed limit. Inorganics and organics, including metal arsenic, cadmium, chromium, lead, silver, selenium and mercury (mercury limit of 0.0002mg/L), depend on the raw material, formulation and production process of the product. For radioactive materials, products made directly of minerals should be measured for total alpha radioactivity and total beta radioactivity. However, when the harmful substances brought into drinking water by the chemical treatment agent for drinking water are not stipulated in the Code of Health of Drinking Water Quality (2001), the permissible limit may be determined by reference to relevant standards at home and abroad, and the permissible limit shall be 10% of the permissible concentration.

When the chemical treatment agent for drinking water is used at the specified dosage, the general sensory index of the treated water shall meet the requirements of the sanitary code for drinking water quality (2001). Among them, when the harmful substance brought into drinking water by chemical treatment agent of drinking water is the substance specified in the sanitary code for drinking water quality (2001), the allowable limit of the substance is 10% of the corresponding specified limit. Including metal arsenic, cadmium, chromium, lead, silver, selenium and mercury (the limit of mercury is 0.0002mg / L), inorganic and organic matters are all determined by the raw material, formula and production process of the product. For radioactive materials, the total α and β radioactivity should be determined for products directly using minerals as raw materials. However, when the harmful substances brought into drinking water by chemical treatment agents of drinking water are not specified in the sanitary code for drinking water quality (2001), it can be determined by referring to relevant standards at home and abroad, and the allowable limit is 10% of the allowable concentration.<br>
