广西工业废水污染状况及影响因素分析

为防治工业废水污染,维护生态安全,通过分析2002²010年广西全区工业废水及主要污染物的排放情况,探讨了广西工业废水排放变化规律及行业特征,对工业经济规模、工业行业结构、治理污染投资以及工业用水重复利用率进行了年际对比,分析了这些因素对工业废水排放的影响。结果表明:广西应重点监测工业废水中砷的排放;农副食品加工业、化工制造业是重点污染行业;纺织业是高能耗、高污染行业;采取调整工业行业结构、对治理污染持续投入、提高工业用水重复利用率等措施,能够在增加工业经济规模的前提下减少工业废水的排放。

Analysis of industrial wastewater pollution and its influencing factors in Guangxi province

In order to combat industrial wastewater pollution and maintain ecological safety, the variation rules and characteristics of the wastewater discharged from industrial companies in Guangxi province were dis- cussed based on the analysis of industrial wastewater and major pollutants emission during 2002 - 2010 in Guangxi. Besides, an inter-annual comparison of scale of industrial economy, structure of industry, investment for pollution control and reutilization rate of industrial wastewater was carried out; finally, the influence of the above factors on industrial wastewater discharge were analyzed. The results showed that： in Guangxi province, arsenic in industrial wastewater should be emphatically monitored; agricultural and sideline foods processing, chemical manufacturing were pollution-intensive industries; textile was a high energy consumption and high-polluting in- dustry. It could draw a conclusion that, taking measures such as： adjusting industrial structure, carrying out sus- tained investment for pollution management and improving reutilization rate of industrial wastewater, could reduce the discharge amount of industrial wastewater on the premise of expending the scale of industrial economy.
