The plumules of Phragmites australis growing in the constructed wetland test pool with high-concentration livestock wastewater and clean water were collected,and the total DNA was extracted for RAPD analysis to explore the genetic variation of Phragmites australis under contamination stress of high-concentration livestock wastewater.

为了探讨芦苇在高浓度畜禽废水污染胁迫下遗传特性的变化，将人工湿地试验池中生长的，受高浓度畜禽废水长期污染胁迫的和未受到污染的供试芦苇材料各20个单株幼芽分别混合提取DNA，采用RAPD分子标记技术在160个随机引物中进行筛选，找到3个能够扩增出差异且重复性较好的RAPD引物：S74、S516和S14。

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。

Wastewater - treated or untreated - that is discharged from drains, sewers, wastewater treatment plants or industrial outfalls into surface waters

处理过或者未经处理，从排水沟，下水道，污水处理厂或者工厂排水口排入地表水体的污水。

Effluent Wastewater - treated or untreated - that is discharged from drains, sewers, wastewater treatment plants or industrial outfalls into surface waters

污水，废水处理过或者未经处理、从排水沟、下水道、污水处理厂或者工厂排水口排入地表水体的污水。

These results provide the scientific basis for determining suitable irrigation frequency and the irrigation volume of papermaking wastewater in saline reed field of Yellow River Delta, which is of great significance to the exploitation and utilization of papermaking wastewater resources.

该研究为黄河三角洲内陆盐碱地区芦苇群落在造纸废水灌溉下的适宜灌溉次数和灌溉水量的确定提供了科学依据，有利于造纸废水资源的合理化开发利用。

The dosage is determined by pH control approach, which does not require a routine jar test. This method can simultaneously determine the optimal pH and economical dosage for oxide-CMP wastewater. The coagulant can be added directly into the raw water without the pH adjusting at first. According to this method, the coagulant acts like a titrant and the pH of the oxide-CMP wastewater is monitored. The optimal dosage is the one that corresponds to a specific pH.

本论文主要以「pH控制法」来决定线上加药剂量值，其与传统瓶杯试验不同的是，其加药逻辑可直接对线上加药进行控制且毋须定期确认参数。pH控制法视混凝剂为酸滴定药剂，直接对进流之氧化层研磨废水进行加药，及至特定pH时，加药停止，此时之加药量即为电性中和去稳之控制点，远较过量加药法经济。

But with the accelerated process of urbanization, urban industrial building high-speed development in recent years, urban sewage and industrial wastewater emissions were rising trend year by year, fertilizer, metallurgy, printing and dyeing, synthetic detergent industries such as wastewater, sewage life Water and water for agricultural use, with a large number of nitrogen and phosphorus compounds, the COD value is high.

但随着城市化进程的加快，城市工业建设的高速发展，近年来城市生活污水和工业废水的排放量呈逐年上升的趋势，化肥、冶炼、印染、合成洗涤剂等行业的废水、生活污水以及农业用水中，含有较大量氮磷化合物，其COD值也比较高。
