A facility with the hydrolysis acidification process , the contact oxidation process and the chemical phosphorus removal process is designed to treat the sewage water in zhouzhuang ancient town , the no . 1 watertown in china , and it is buried under ground for the sake of protecting the environment 摘要采用水解酸化接触氧化化学除磷工艺处理“中国第一水乡”周庄古镇的生活污水，考虑到对环境条件要求较高，池体采取地埋式建设。
From the four aspects , direct treatment effect , treatment ability , treatment stability and impact load resistance , the thesis quantitatively analyzes the treating effect of normal contamination removal ( ss , bod5 , codcr ) and nitrogen and phosphorus removal ( nh3 - n , tn , tp ) 从污水处理的直接效果、处理能力、处理稳定性和耐冲击负荷能力四个方面,对各工艺普通污染物( ss , bod5 , codcr )和脱氮除磷( nh3 - n , tn , tp )的处理效果进行定量分析。
Results showed that higher efficiency of cod removal would not be got in electrode - biology reactor than that of the ordinary biology reactor at the experimental conditions , but phosphorus removal would be got especially in improving the degree of release phosphorus during the period of anaerobic 结果表明：在试验条件下，外加电场生物反应器比普通生物反应器具有更高的除磷效率，并能在厌氧阶段促进磷的释放，而cod去除率提高并不明显。
The studies of phosphorus removal by adsorption are mainly focused on development of adsorbents , including cheap natural materials or industry solid wastes and their modification , traditional activated alumina and its modification , other porous materials and synthesized adsorbents according to their different applied situations 吸附法除磷的研究主要表现在吸附材料的研究方面，基于应用场合的差异，包括廉价的天然材料、工业废渣及其改性物、传统的活性氧化铝及其改性物、其他多孔物质及人工合成的高效吸附剂等。
In order to determine the influence of environmental variations on phosphorus removal mechanisms in a combined pond - wetland system , the dominant removal mechanisms of phosphorus in different treatment unit and their influence on phosphate transformation between sediment and water column were investigated through analyzing the differences of phosphorus fractionation with water conditions 摘要为确定环境差异对磷去除机制影响，利用组合塘湿地生态处理系统中各单元环境与磷形态分布的差异，分析各单元磷的主导去除机制及其对底泥和水体中磷迁移过程的影响。
Introducing several main dephosphorization methods of wastewater , the paper discussed chemical deposition dephosphorization method , biological dephosphorization method and constructed wetland dephosphorization method in detail and analyzed their advantages and disadvantages : chemical deposition dephosphorization has higher phosphorus removal rate , but it will bring a large mount of sludge ; biological dephosphorization is more convenient for operation , but phosphorus removal rate is lower ; constructed wetland is a low - cost technique to remove phosphorus , but it should be developed 摘要介绍了污水除磷的几种主要方法，并对化学沉淀法除磷技术和生物除磷技术以及人工湿地除磷技术进行了详细论途，简要分析了各种方法的利弊：化学法除磷效率较高，但会产生大量化学污泥；生物法除磷操作简单，但除磷效率较低；人工湿地除磷技术廉价高效，但有待进一步发展完善。
