随着世界石油化学、钢铁、电力等大型现代化工业的出现,导致对水、土壤、大气环境污染日趋严重,破坏生态循环。为此,日、美、西欧等工业发达的先进国家愈来愈重视环境保护。日本政府把环境保护作为一种国策,严格控制“三废”排放,它依靠栗田工业、伯东化学等大型水处理公司的技术力量不断研制、开发新型水处理与防垢药剂,以至共水处理技术与药剂日趋领先。兹就以下几方面作一概述。
With the emergence of large-scale modern industries such as petrochemical, steel and electric power in the world, pollution to water, soil and atmosphere has become increasingly serious and the ecological cycle has been destroyed. To this end, Japan, the United States, Western Europe and other advanced industrialized countries pay more and more attention to environmental protection. The Japanese government regards environmental protection as a national policy and strictly controls emissions from “three wastes”. It relies on the technological capabilities of Kurita Industries, East Chemical and other large-scale water treatment companies to continuously develop new water treatment and anti-scaling agents, Processing technology and pharmaceuticals are increasingly leading. Here is a summary of the following aspects.
