摘要：明珠湖旅游区目前还没有完整的污水收集系统，污水排放呈无序状态，雨污不分，其排放主要是依靠土壤的自然渗透，或明渠式自排的管道就近排入河道，环境污染状况较为严重，故需建立一座污水处理厂。而在此之前，需完成建设项目的环境影响评价。本课题为该污水处理厂建设前的评价，主要包括以下几点：通过调查、监测等方法了解当地环境状况，进行工厂选址方案和污水处理工艺的比较；对当地的水、大气以及声环境质量做出评价；利用数学模型、类比调查等方法对明珠湖污水处理厂施工期间造成的影响和它建成之后将对当地所产生的影响作出预测；列出公众参与的内容及意见;最后，提出结论与建议，包括建设项目拟采取的防治措施。

The environmental impact assessment of Pearl Lake sewage treatment plant
Abstract: There is no complete sewerage system in Pearl Lake District，the discharge of wastewater is in disorder,rainwater and sewage are classified,their main emissions rely on the natural osmosis of soil,or open channel from the exhaust pipe into the nearby river,Environmental pollution is relatively serious, so we need to build a sewage treatment plant.Before this, we need to complete environmental impact assessment of the construction project.This issue is the evaluation before the construction of the sewage treatment plant,including the following points:we through investiging, monitoring and other methods to realize the condition of the local environment,and compare factory location scheme and sewage treatment process ;We evaluate quality of the water ,air and sound environment ;And we make a prediction about effects during the period of construction and the effect after it was built caused by the pearl lake sewage treatment plant through using mathematical model and investigation analogy;Listing the contents and opinions participated by the public and the results of the survey;Finally, we put forward the conclusion and the suggestion including prevented measures planned and taken by construction project.
Keywords: Pearl Lake sewage treatment plant;The environmental impact assessment;Impact prediction
