污染

The washing experiment of soil contaminated by petroleum alkane was performed with two kinds of biosurfactants in laboratory. The results showed that biosurfactant would enhance on removal of residual alkane in soil, after washing with 20 pore volume solution the removal rate with BS-UC and MELs were three times and twice as that of water, respectively.

Aimed at the increasing eco-environmental problems, including water shortage, water pollution, soil salinization, water loss and soil erosion, loss of function of the channel and river, biocenose degradation, etc, which severely infected the sustainable development for irrigation area, the main works in this paper are summarized as followed: constituting the measures of water resources shortages for developing agricultural water-saving technologies and adjusting agricultural structures; constructing the water polluting control and purification system of Mushroom lake: source control and decrement-sewage collection and treatment - channel ecological interception - wetland treatment -reservoir purification; putting forward the systematic projects for soil salinization and water loss and soil erosion of the integrated application of water conservancy agriculture and forestry.; constructing the ecological impervious channel model in west bank, from all of which theoretical bases and technical support for the eco-environmental rehabilitant in Manasi irrigation area were offered. All of these works were based on data collection, technical analysis, on-the-spot investigation, experimental research and technical development about Manasi irrigation area, etc.

通过对玛纳斯河灌区进行资料查阅收集、理论分析、现场勘察、试验研究和技术开发等途径，针对玛纳斯河灌区存在的水资源短缺、水体污染、土壤盐渍化、水土流失、沟渠河道功能缺失、生物群落退化等日益突出的严重影响灌区可持续发展的生态环境问题，制定了发展农业节水技术、调整农业结构的灌区水资源短缺的措施，构建了&源头控制减量-污水收集处理-引水调控-渠道生态截留-湿地生态处理-库区生态净化&的蘑菇湖水污染控制与净化系统；提出水利、农业、林业综合应用的灌区土壤盐渍化、水土流失问题的综合治理方案；构建了西岸大渠生态防渗型渠系模式，为玛纳斯河灌区生态环境修复建设提供了理论基础和技术支持。
