海南省"十三五"时期工业废水排放特征研究
Study on the Characteristics of Industrial Wastewater Discharge in Hainan Province During the 13th Five-Year Plan Period
摘要
Abstract
In order to explore the pollution status and spatial and temporal distribution characteristics of in-dustrial wastewater in Hainan Province during the 13th Five-Year Plan period,equal standard pollution load method,equal standard pollution load of unit output value method,cluster analysis method and Daniel trend test method were used in this study.The pollution load intensity,environmental efficiency,industry contribu-tion difference and regional distribution characteristics of industrial wastewater pollutants in this period were systematically analyzed.Results showed:(1)In 2016,the equal standard pollution load of pollution sources and equal standard pollution load of unit output value reached the peak.It showed that the pollution intensity was the highest and the environmental efficiency was the lowest during this period.(2)The pollutant with the highest total equal standard pollution load was Total Nitrogen(TN),followed by Total Phosphorus(TP),with values of 6 213.5 and 1 493.4,respectively.(3)The main source industry for Chemical Oxygen Demand(COD)pollutant was the paper and paper products industry,accounting for 40.9％of the equal standard pollution load ratio.For TP pollutant,the main source industry was the agricultural and sideline food processing industry,with a ratio of 56.2％.The main source industry for ammonia nitrogen(NH3-N)and TN pollutants were the chemical raw materials and chemical products manufacturing industry(hereinaf-ter referred to as the chemical raw materials manufacturing industry),with equal standard pollution load rati-os of 45.2％and 46.8％,respectively.(4)Chengmai County was classified as a high-risk zone for industrial wastewater pollution,followed by Yangpu Economic Development Zone as a moderately high-risk zone.Haik-ou City,Sanya City,Wenchang City and Dongfang City were designated as moderate-risk zones,while the re-maining cities and counties fell into the low-risk category.In Hainan Province,priority should be given to the remediation of wastewater pollution originating from the paper and paper products industry,the agricultural and sideline food processing industry,and the chemical raw materials manufacturing industry.Additionally,the emission of industrial wastewater pollutants in Chengmai County and Yangpu Economic Development Zone should be subject to strict regulation.The results of this study are expected to serve as a scientific basis for industrial environmental governance and industrial restructuring within the Hainan Free Trade Port.关键词
