Summary
The article presents some of initial results on the waste water treatment process of vermicelli production at the trade village Phu Do - Tu Liem - Ha Noi by active mud method. Specific characteristics of this method are easy to conduct and bring a high effect. The treatment process includes three main steps: waste water of vermicelli production process is deposited in 18 hours. then diluted with the rate of one production waste water per two domestic waste water and supplied active mud with the rote of 5 percent, and here simultaneous combination of gas scour process during 21 hours. Ater that waste water is deposited and discharged outside. The obtain results are: amount ofCOD has increased from 7800 mg/l to have 192 mg/l left and the obtained performance of 98 percent. Besides. the project also recommend households to substitute biogas for currently charcoal.
