In view of the characteristics of the secondary settling effluent of municipal wastewater treatment plant in our country three kinds of advanced wastewater treatment technology including flocculation, sedmentati-on and sand filter and of microflocculation filtration and direct filtration were discussed in this paper. A flocculation tank with screen, a settler fitted with deflectors inclined plote and a coarse sand filter backwash with air and water simultaneously were adopted as the...

In view of the characteristics of the secondary settling effluent of municipal wastewater treatment plant in our country three kinds of advanced wastewater treatment technology including flocculation, sedmentati-on and sand filter and of microflocculation filtration and direct filtration were discussed in this paper. A flocculation tank with screen, a settler fitted with deflectors inclined plote and a coarse sand filter backwash with air and water simultaneously were adopted as the test devices and poly -ferric sulphate was selected as flocculant. The test scale was 120m3/d.
