杭州市阳台废水排放特征研究

摘要阳台废水造成区域水污染已经成为公民关注的热点。常见的雨污混接污染起始原因是施工过程中雨污管道错接及居民开放阳台封闭并安放洗衣机后洗涤废水排入雨水管道造成的。根据阳台的类型可将阳台水产生的形式分为以下三类封闭阳台,敞开式阳台,工作阳台。均不同程度上导致了阳台废水的产生于排放。对阳台废水排放的调研，主要是对错误的废水排放渠道——生活洗衣废水排入雨水管道带来的影响的考察。而经检测，洗衣废水的Ph值超过了9，COD（化学需氧量）则达到了573mg/L，远远超过Ⅲ类水标准。经我们大概估算，一个简单的三口之家，每年产生的洗衣污水约6。5 吨，综合杭州市5个区的洗衣机安放位置，都有1/4到1/3的居民将洗衣机安放在阳台。而将洗衣机安放在阳台的比重越大，洗衣废水从雨水管道排出的比例就越大。各个区都有10%到15%的居民将洗衣废水从雨水管道排除，再加上城市人口基数较大，可以预见洗衣废水对周边河道影响之大，本研究采用调查问卷于实地采样检测的方式，研究杭州市阳台废水的排放特征。本研究为杭州市阳台废水排放研究与控制提供了一定的事件依据，并对杭州市阳台废水治理提供了一定的理论依据。89254

Abstract The balcony area water pollution caused by wastewater has become a hot topic of citizens。 Common rain sewage mixed by pollution reasons is of moderate rain sewage pipeline construction process the initial and the residents open balcony closed and placed after washing machine washing wastewater pipeline caused by the rain。 According to the type of the balcony the balcony water forms can be pided into the following three types of closed balcony, open the balcony, the balcony。 All contributed to the balcony wastewater produced in different emissions。 Research on the balcony wastewater emission, mainly for the wrong laundry wastewater discharge channels - life waste water discharged into the effects of rainwater pipeline inspection。 And after the examination, laundry wastewater pH value of more than 9, COD (chemical oxygen demand) is reached 573, far more than Ⅲ class water standard。 By our estimates, probably a simple family of three, each year of laundry wastewater is about 6。5 tons, comprehensive Hangzhou 5 position, the washing machine washing machine has a quarter to a third of the residents in the balcony。 The greater the proportion of washing machine and put in the balcony, laundry wastewater from the greater the proportion of drainage discharge。 Each district has 10% to 15% of the residents to exclude laundry wastewater from rainwater pipe, coupled with the urban population is larger, can foresee a laundry wastewater impact on the surrounding river, this research adopts the questionnaire on the field sampling inspection way, research the balcony wastewater discharge characteristics of Hangzhou。 This study provides the balcony wastewater research and control of Hangzhou based on certain events, waste water treatment of Hangzhou balcony and provides certain theoretical basis。
