Abstract: |
Because of large amount, high water content and environmental stresses of oily sludge, quantitative reduction and dewatering of oily sludge requires particular attention. Inveatgating on the dewatering performance of two kinds of oily sludge from Shengli Oil Production Plant through pressure filtration method, The influences of adding different filter aids and flocculants on dewatering performance of oily sludge by pressure filtration method were experimentally investigated. The effect of these agents were investigated and finally excellent auxiliary agents were selected. Form trials of the laboratory scale frame filter and the skid-mounted pilot plant on the spot, it found that adding filter aid and flocculant are of advantage for filtering and the filter cake has low water ratio, which can meets the transportation requirement.
