摘　　要：当前,深圳市企业和居民生活废水排放需求量不断增加,但配套管网系统不到位,致使各类生活废水无处可去,形成了雨污混合的局面。文章结合深圳市城市污水管网系统建设项目,分析了其在城市排水系统建设中的应用成效,且对同一工况下三种型号的曝气设备进行了试验,同步实施了水质监测。研究表明,三种掺气槽均可改善水体的透明度,但是喷射掺气和推流掺气会形成大而破碎的泡沫,而且在同等水体条件下氧气的传输效果比微纳米掺气差。在试验最后阶段,随着微纳米曝气装置的强化,污泥的氧化还原电位明显提高,因而采用微纳米级曝气方式较为推荐。At present,the demand for domestic wastewater discharge from enterprises and residents in Shenzhen City is increasing,but the supporting pipe network system is not in place,resulting in nowhere to go for all kinds of domestic wastewater,forming a mixed situation of rain and sewage.Based on the construction project of urban sewage pipe network system in Shenzhen City,this paper analyzes its application effect in the construction of urban drainage system,and tests three types of aeration equipment under the same working condition,and implements water quality monitoring simultaneously.Studies have shown that all three aeration tanks can improve the transparency of water,but jet aeration and plug-flow aeration will form large and broken foam,and the transmission effect of oxygen is worse than that of micro-nano aeration under the same water condition.In thefinal stage of the test,with the enhancement of the micro-nano aeration device,the oxidation-reduction potential of the sludge is significantly improved,so the micro-nano aeration method is more recommended.
