磺化粗菲(以下称S-808)是我国科技人员自己研制的一种胶磷矿浮选剂,经有关部门鉴定认为选矿效果好、毒性低。但S-808作为选矿剂,使用量和废水量都相当大,且随同选矿尾水排入矿区附近的江、河、湖泊,波及面很广,若废水处理不当或不加限制的任意排放,即使毒性虽小,亦有可能污染水源,影响水生物和农作物生长, Sulfonated crude Philippine (hereinafter referred to as S-808) is a kind of phosphate rock flotation agent researched and developed by our country’s scientific and technical personnel, which is appraised by the relevant departments and has good dressing effect and low toxicity. However, S-808 as a dressing agent, the amount and volume of waste water are quite large, and along with the tailings discharged into the mine near the river, river, lake, a wide range of waves, if the wastewater treatment improper or unrestricted arbitrary emissions, Even though the toxicity is small, it is possible to pollute the water and affect the growth of aquatic organisms and crops.
