净水渔业生态修复水源地水质研究

Study on Water Quality of Water Source for Ecological Restoration of Water Purification Fishery

摘要: 净水渔业生态修复主要是利用水生生物的吸收、代谢功能将水体有害物质转化迁移出水体，达到改善水质的目的，是环保型、低成本、高效益的水质保护处理技术手段。本研究以哈尔滨市后备水源地西泉眼水库为研究基地进行了净水渔业生态修复保护水质研究。通过发展净水渔业，哈尔滨市西泉眼水源地在2010~2013年的四年内共清除氮肥42,600 t，磷肥29,820 t，吸收二氧化碳145,550 t。有机污染物清除后，水库水质改善效果明显，2010年水库水体氨氮、总磷和总氮含量相比2009年分别下降了42.1%、42.3%和36.2%。净水渔业在消除有机污染的同时，碳汇效果也十分明显，可起到缓解温室效应的作用。

Abstract: The ecological restoration of water purification fishery mainly uses the absorption and metabolism function of aquatic organisms to transfer harmful substances from water body to improve water quality. It is an environmentally friendly, low-cost and high-benefit water quality protection and treatment technology. In this study, Xiquanyan Reservoir, a reserve water source in Harbin, was used as the research base to study the ecological restoration and water quality protection of water purification fishery. Through the development of water purification fishery, the Xiquanyan Water Source in Harbin City removed 42 600 tons of nitrogen fertilizer, 29,820 tons of phosphorus fertilizer and absorbed 145,550 tons of carbon dioxide in the four years from 2010 to 2013. After the removal of organic pollutants, the water quality of the reservoir has been improved significantly. Compared with 2009, the contents of ammonia nitrogen, total phosphorus and total nitrogen in the reservoir water decreased by 42.1%, 42.3% and 36.2% respectively in 2010. Purified water fishery can eliminate organic pollution, and at the same time, the carbon sink effect is also very obvious, which can play a role in mitigating the greenhouse effect.
