The results showed that the free-living marine nematodes were the dominant group the percentage of which in the total number of meiofauna ranging betwean 76.1%~96.3%. The abundance of meiofauna in old mangrove district was the least and in bare beach where waste water flows was the most. There were a total of 37 putative species in the samples. The total number of recorded species was the lowest in the new mangrove district, and highest in the old mangrove district. The species diversity indexes, species evenness indexes and richness indexes in old mangrove district were all higher than those in new mangrove district. The dominant species and feeding types were different in three types of habitats.

结果表明：海洋线虫是凤林红树林中小型底栖动物中的绝对优势类群，占到小型底栖动物的76.1%~96.3%；从丰度来看，旧区白骨壤林中小型底栖动物的数量较少，有污水流过的光滩数量较大；4个断面共鉴定出海洋线虫37种，其中新区秋茄林中的生物多样性指数较低，旧区白骨壤林中群落具有较高的物种多样性；从出现的物种来看，新区秋茄林、旧区白骨壤林和光滩上出现的优势种和摄食功能群的类型各不相同。

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。

In the environmental pollution control, as a technical means, biotechnology has high efficiency, mild reaction conditions, and other advantages, its governance and the restoration of environmental pollution has played a tremendous role for the he**y metal wastewater, petroleum wastewater, grease wastewater, pesticides wastewater, domestic sewage and provides a very effective way.

在环境污染治理中，作为一种技术手段，生物技术具有高效性，反应条件温和等优点，它对环境污染的治理和修复发挥了巨大作用，为重金属废水，石油废水，油脂废水，农药废水，以及生活污水提供了一条十分有效的途径。

Every year, waters on earth receive large quantities of wastewater from industry, agriculture, fish and poultry raising, and municipal sewage treatment plants. Consequently, the aquatic environment on the earth is under a serious challenge from a very large quantity of pollutants such as antibiotics, insecticides, herbicides, hydrocarbons, etc., contained in the domestic wastewater, industrial and agricultural waste water and illegal effluents. In particular, with the development of intensive aquiculture and poultry, the effluent pollution has recently become more and more serious with more attentions. Furthermore more and more chemical pollutants discharged into aquatic environment have been detected with the advancement of analytical techniques. These chemicals can cause toxic effects on water habitats after discharged into aquatic environment.

每年有大量来自工业、农业、养殖业和城市污水处理厂的废水被排入到水环境中，因此，地球上的水环境面临大量来自生活废水、工农业废水、非法排放的废水及其它废水的污染物质(如抗生素、杀虫剂、除草剂、烃等)的严重挑战，特别是近年来随着集约化养殖的发展，废水污染问题日益突出，并且随着分析手段的进步，能够检测到被排入水环境中的化学污染物质也越来越多，这些化学污染物对水环境中的生物产生有害影响。

Biodegradation technology was a new sewage disposal technology, which developed quickly in recent years.

生物降解技术是近年来发展迅猛的一种新型污水处理技术。

The principle, characteristics and influential factors of heavy metals removal with biological reduction of sulfate are studied in this paper. It is feasible and effective to removal heavy metals with biological method and it has reliable significance for the treatment of heavy metals wastewater.

文章对硫酸盐生物还原法去除重金属的原理、特点、影响因素进行了研究，证明该法去除重金属是可行和有效的，它对于处理重金属污水具有现实意义。

The biological processes in the biological treatment step are also present in natural watercourses, but in the wastewater treatment plant these processes are more effective.

生物处理过程同样发生在自然水道，但在污水处理厂，这些过程更加有效。

In 1968 extensive research on direct potable reuse was conducted in Windhoek, Namibia.

自1960年以来，迫于调整压力和水的缺乏，一份深入的调查结果给水再利用工程的健康风险和治疗系统提供了有价值的洞察力。1965年，以色列健康部门出版章程允许对农作物灌溉实行二次污水再利用，还有被排除在外的不用煮可以吃的蔬菜作物。1968年在温得和克和纳米比亚对直接可饮用的再利用进行了广泛的研究。1972年在美国，有一件重要事件就是通过了联邦水污染控制法案（PL92－500）&修复并且维持民族水资源的化学，物理和生物的完整性。&
