在资本主义国家,资本家唯利是图,追求高额利润,在工业中大量排放有害废水,严重地污染环境,危害人民的健康,甚至夺去人民的生命,给人民带来了灾难。含汞废水已成为世界上危害最大的工业废水之一。含汞废水的污染及其危害含汞废水的来源使用汞阴极电解槽的氯碱工业用汞量最多,排放的含汞废水也最多。据美国的统计,每生产一吨氯约损失汞0.1公斤;而据加拿大的统计每生产一吨氯约损失汞0.25公斤。瑞典的氯碱工业每年随废水流失的汞量达35吨。汞的另一种重要的用户是炸药制造工业,其中使用雷酸汞作起爆剂。在制造雷酸汞过程中产生含汞废水。在农药制造中广泛使用无机汞和有机汞化物制造杀虫剂、杀菌剂、防霉剂和选种剂等,在制浆造纸工业中用汞制剂作循环用水的杀菌剂和粘絮防除剂,从而使产品、废水和附近空气中都含汞。现在虽大都用毒性小的粘絮防除剂取代汞制剂,
In capitalist countries, the capitalists are mercenary, pursue high profits, discharge large quantities of harmful waste water in industries, seriously pollute the environment, endanger people’s health, and even deprive their people’s lives, thus bringing disaster to the people. Mercury-containing wastewater has become one of the most hazardous industrial wastewaters in the world. Sources and Sources of Mercury-Containing Wastewater Sources and Sources of Mercury-Containing Wastewater Mercury-based cathodes are most commonly used in chlor-alkali industry and mercury-containing wastewater is also emitted the most. According to United States statistics, about 1 kg of mercury is lost per ton of chlorine produced, while about 0.25 kg of mercury is lost per ton of chlorine produced in Canada. The chlor-alkali industry in Sweden discharges 35 tons of mercury per year with wastewater. Another important user of mercury is the explosives manufacturing industry, which uses mercury trihalide as a primer. Mercury-containing waste water is produced during the manufacturing of mercury acid. In the manufacture of pesticides, inorganic mercury and organic mercury compounds are widely used in the manufacture of pesticides, bactericides, fungicides and seed selection agents, fungicides and fouling control agents for recycling water in the pulp and paper industry using mercury preparations, So that products, waste water and nearby air contains mercury. Although most now use toxic small sticky control agent to replace mercury,
