1、毕业设计（论文）题目UCT生活污水脱磷除氮效果研究系（部）制药与环境工程系专业环境监测与治理技术指导教师梁贤君（校内）作者王波完成日期2012.5.15-35-摘要水是人类生存的生命线，是经济发展和社会进步的生命线，是实现可持续发展的重要物质基础。为加强水污染防止，我们应在加大环境执法检查和环境影响评价等推进工业废水、废气治理的基础上，加强城市的综合卫生管理，使街面保持干净，减少因风吹、雨水等因素将脏物带入河流也非常重要。这就需要对自由市场、餐馆、外来人口聚居区进行严格的卫生管理，对建设工地卫生实行严格监督，对产生污染的路边小生意、洗车点或进行环境改造、或取缔。同时，应健全垃圾处理站点网络（尤

2、其是公共场所），让人们垃圾有处可弃，减少因无垃圾站（箱）而导致的垃圾随意丢弃。应在沿河设置一些公共厕所，让在外活动的人们感到方便，减少因为没有厕所而将河沿当厕所的现象。并加强对大众加强保护水质的教育，除了沿河树立一些警示牌，呼吁人们注意保护水质外，新闻媒体继续对大众进行环境保护的教育和监督。为了更好的对污水进行处理，消除污水中的氮、磷成分，我们对UCT脱氮除磷效果的研究以期为人们创造更安全的饮水环境。UCT工艺是一项新的污水处理工艺，在脱氮、除磷及除磷脱氮方面有独特的效果。因此，研究UCT工艺的设计技术能够为改善城市废水的脱氮除磷效果提供重要的理论基础。多功能UCT工艺，可根据水质、水量的变化

3、以及季节的不同将系统灵活调整为常规UCT、改良UCT、A2/0和倒置A2/O等四种不同的处理工艺，从而保证了在不同的环境条件下均能达到最佳的运行工况，运行结果表明，该工艺具有较高的COD、BOD、SS去除率。-35--35-目录前言···············································51、UCT工艺·······································61.1、UCT工艺简介·······································61.2、UCT工艺影响条件·························
