Assessment of Water Environment Quality in Henan Province
摘要
Abstract
Water environment quality evaluation, as one of the scientific proofs for water environmental quality management and planning, has become one of the important measures for environmental management. Based on the environment bulletin of statistic data of Henan province, the Environmental Quality Standard for Surface Water (GB 3838─2002) and the Environmental Quality Standard for Ground Water (CB/T 14848─93), water environment quality of 18 provincial cities and 10 provincial directly governing counties in Henan province were evaluated. The results showed that chemical oxygen demand and ammonia nitrogen emissions decreased by 2.62%and 3.61%, respectively, which was higher than the national average decrease value in 2014. However, the provincial wastewater discharge amounts increased during the study period, which increased by 2.48% and 2.16% in 2014, respectively compared with the same period of last year. The provincial surface water quality was moderately polluted, and water quality in individual river section was severely contaminated. Surface water main pollution factors were chemical oxygen demand, five day biochemical oxygen demand, ammonia nitrogen and total phosphorus. The provincial Yangtze River water quality was good, while water quality of provincial Haihe river basin had been in severe pollution levels. Groundwater quality in most of the cities was at II level, while serious in Kaifeng and Puyang city. The water quality of centralized drinking water source was at II level in Henan Province. The reservoir water quality kept in the class II standard in recent years, while water environment quality remarkably degradated in several reservoirs including Shimantan Reservoir, Zhaopingtai Reservoir, Gushitan Reservoir, and Suyahu Reservoir, in which main pollutants were permanganate, total phosphorus, five day biochemical oxygen demand, and petroleum. Although the water environmental quality in Henan province has been greatly improved, the provincial surface water environmental quality is still serious. It is especially significant that water pollution of provincial Haihe river basin has been ranked the first across the province in recent years, which seriously restricts the sustainable development of social economy and the construction of beautiful Henan.关键词
