现场污水处理系统(OWTS)是世界各地污水处理基础设施的重要组成部分。在美国,OWTS服务于全国20%至25%的家庭。虽然获得化粪池处理似乎是一个普遍存在的问题,在美国,这个问题得到了相对较少的关注。在这里,我们检查了美国格鲁吉亚州县级对OWTS数量和治疗方案的估计。我们还使用了从废水处理设施收集的市政和区域数据,以突出化粪池处置的处理方案之间的关系,化粪池处理的成本,以及交付给接收工厂的化粪池数量。我们保守估计,该州每天至少应产生93.2万加仑(GPD),但只有50万至65万GPD的处理能力。该州超过70%的县不支持市政处理腐化物的选择。我们在市政和区域层面报告的数据突出了交付给处理设施的化粪池数量与处理价格之间的负面关系。地方和州机构必须制定政策,并筹集所需资金,以管理其管辖范围内产生的废水的整个生命周期。
On-site wastewater treatment systems (OWTS) are essential parts of wastewater treatment infrastructure throughout the world. In the United States, OWTS serve between 20% and 25% of homes in the country. Though access to septage treatment appears to be a ubiquitous problem in the United States, this issue has received relatively little attention. Here, we examined county-level estimates of the number of OWTS and treatment options in the state of Georgia in the United States. We also used municipal and regional data collected from wastewater treatment facilities to highlight relationships among treatment options for septage disposal, the cost of septage treatment, and the amount of septage delivered to receiving plants. We conservatively estimate the state should generate at least 932000 gallons per day (GPD) but has the capacity to treat only 500000–650000 GPD. More than 70% of counties in the state do not support municipal treatment options for septage. The data we report at the municipal and regional levels highlight negative relationships between the amount of septage delivered to treatment facilities and the price of treatment. Local and state agencies must develop policies and generate the funding needed to manage the entire life cycle of wastewater generated within their jurisdictional boundaries.
