东江源头区典型村庄厨余废水水质分析

Quality Analysis of the Kitchen Wastewater from Typical Villages in the Source Region of Dong River

在东江源头区选取了3个典型村庄,对其厨余废水的水质进行调查分析。结果表明:东江源头区沿江村庄农户家庭厨余废水中TP、NH 3-N和COD浓度远远超过《城镇污水处理厂污染物排放标准》中一级A标准限值,需经进一步处理后排放;夏秋季节,厨余废水中TP、NH 3-N、COD浓度高于春季;村庄的经济发展水平对厨余废水水质有一定影响,经济发展水平高的村庄排放的厨余废水中污染物的浓度较经济水平较低的村庄厨余废水中污染物的浓度低。

In this study, three typical villages in the source region of Dong River were chosen to investigate the quality of kitchen wastewater. The results showed that concentration of TP, NH3-N and COD in the wastewater from peasant household far exceeded the standard limits of Grade A regulated in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant, so the wastewater should be further treated before discharge. Concentration of TP, NH3-N and COD in the kitchen wastewater were higher in summer and fall than that in spring. Economic development levels of the villages had a certain effect on the quality of the kitchen wastewater. Concentration of pollutants in the kitchen wastewater was lower in the village with high economic development level than that in the village with lower economic level.
