工矿企业的生产用水和生活用水都是通过消耗一定的能源取得的。据统计,各地生产的自来水约有60～80％是供给工矿企业的生产用水。一个年产150万吨钢的钢铁企业,全年用水量约4亿m~3,耗电0.92～1.44亿度。1978年11个重点钢铁联合企业的吨钢用水综合指标为136～416m~3,平均为243m~3。而日本1975年10家主要钢铁企业的吨钢用水综合指标为112～250m~3,平均为140m~3,两者相差甚远。说明我国钢铁企业用水浪费很
Industrial and mining enterprises of production water and domestic water are obtained through the consumption of certain energy. According to statistics, about 60-80% of the tap water produced in each place is for the production of water for industrial and mining enterprises. An annual output of 1.5 million tons of steel steel companies, the annual water consumption of about 400 million m ~ 3, power consumption of 0.92 to 144 million degrees. In 1978, 11 key iron and steel conglomerates had a comprehensive indicator of water consumption per ton of steel of 136 to 416 m 3, with an average of 243 m 3. However, in Japan, the ten major iron and steel enterprises in 1975 showed a comprehensive index of tonnage of steel of 112 to 250 m 3, with an average of 140 m 3. Illustrate that China’s iron and steel enterprises water waste
