海河流域是我国七大江河受工业污染最严重的河流之一。1980年全流域日排污水量达到1006.8万吨,年排污水总量约31.4亿立方米,全流域的污水排放量与多年平均迳流量的比为1:9.3,这样大的污水比数,天然水体无力使其污染物降解自净而保持水质良好。从水资源量上看,海河流域年均迳流量约292亿立方米,仅为全国总迳流量的1.1%,而本流域的人口却占了全国人口的十分之一,按人口平均,每人每年只占有水量292立方米(不包
Haihe River Basin is one of the seven rivers in China with the most serious industrial pollution. In 1980, the daily discharge of water in the whole basin reached 10,068,000 tons and the annual discharge of sewage was about 3.14 billion cubic meters. The ratio of the discharge of sewage in the whole basin to the average flow rate in many years was 1: 9.3. Such a large proportion of sewage, natural water body Inability to degrade their contaminants to maintain good water quality. In terms of water resources, the annual average flow in the Haihe River Basin is about 29.2 billion cubic meters, accounting for only 1.1% of the country’s total discharge, while the present basin accounts for one tenth of the national population. According to the average population, Only 292 cubic meters of water per person per year (not included
