农户庭院型生态工艺原位处理源分离后的洗涤废水

选择长江三角洲地区有一定代表性的乡村家庭，开展了厌氧池-多级布水模块化人工湿地原位处理源分离后的废水的实例研究，旨在掌握乡村家庭源分离后废水的水质特征，并通过厌氧池-多级布水模块化人工湿地，重点解决乡村家庭源分离后的废水原位净化达标排放问题。结果表明，耗氧有机物(以COD计)、BOD₅、LAS (linear alkylbenzene sulfonates)是洗涤废水、灰水中的主要污染物质；季节变化、进水浓度对厌氧池-多级布水模块化人工湿地处理源分离后的废水中的耗氧有机物、LAS影响不显著，但季节变化对粪大肠菌群影响显著。总体上，2户农户的设施出水均符合《农田灌溉水质标准》(GB 5084-2005)水作作物的相关规定。

Farmer courtyard-type ecological process for onsite treatment of washing wastewater after source separation

In this study, two representative rural households in the Yangtze River Delta were taken as test sites, then a case study of on-site treatment of wastewater after source separation by an anaerobic tank- modular constructed wetland with multi-level water distribution (AT-MCW) was conducted. The aims of this study were following: grasping the water quality characteristics of rural household wastewater after source separation, and solving the problem of up-to-standard discharge of wastewater after source separation from rural households through on-site treatment with AT-MCW. The results showed that oxygen-consuming organic matter (in COD), BOD5 and LAS (linear alkylbenzene sulfonates) were the main pollutants in washing wastewater and grey water; Seasonal changes and influent concentration had no significant effects on the treatment of oxygen-consuming organic matter and LAS in the two types of wastewater by AT-MCW, but seasonal changes had significant effects on fecal coliform; In general, the effluents from the facilities of AT-MCW in two rural household could meet the standard limit of water crop types in the Standards for Irrigation Water Quality (GB 5084-2005).
