摘要
越南市场废水造成的污染已发生多年。特别是，河滨市场未经处理的废水经常直接排放到河流中，增加了河流的污染物负荷。安厝街市的污水平均每天约有19立方米排入安厝河。然而，由于缺乏投资资金等诸多原因，废水处理系统尚未在市场上建成。由生物炭固定床组成的滴流过滤器(TF)是一种成本可接受的技术，可以有效地处理有机污染物、营养物质和悬浮物等参数。在本研究中，采用生物炭培养基的TF处理安cuu市场废水的模型有效运行，有机负载量(OLR)在188 ~ 550 gBOD5.m3之间。水力加载率(HLR)为532 ~ 1899 l - m-2.day-1。生物炭滴滤器对BOD5的去除率为97%，COD的去除率为92%，TSS的去除率为97%，PTot的去除率为66%，NTot的去除率为62%。
STUDY ON CAPACITY OF A TRICKLING FILTER USING BIOCHAR MEDIUM FOR TREATING WASTEWATER FROM AN CUU MARKET IN HUE CITY, VIETNAM
Pollution caused by market wastewater has occurred for many years in Vietnam. In particular, untreated wastewater from a riverside market is often directly discharged into a river, increasing loads of pollutants for the river. Every day, An Cuu market wastewater is averagely discharged about 19 cubic metres into An Cuu river. However, a wastewater treatment system has not been yet built at the market due to many reasons including the lack of investment capital. A Trickling filter (TF) consisting of a fix bed of biochar is a cost acceptable technology, effectively treating parameters like organic pollutants, nutrients and suspended solids. In this study, a model of TF using biochar medium for An Cuu market wastewater treatment were effectively operated with the organic loading rate (OLR) varying from 188 to 550 gBOD5.m3.day-1 and the hydraulic loading rate (HLR) from 532 to 1899 L.m-2.day-1. The biochar trickling filter showed high removal efficiencies: 97% BOD5, 92% COD, 97% TSS, 66% PTot and 62% NTot.
