杭钢炼铁厂有342m~3、302m~3、255m~3高炉各一座,共计有效容积为899m~3。正常生产时,产生高炉煤气洗涤污水为1200m~3/h,污水含尘浓度为1000mg/L左右,最高可达3000～4000mg/L。经沉淀池沉淀泥浆采用园盘真空过滤机进行脱水处理的传统工艺。因这种传统的老工艺存在着工艺流程复杂、附属设备多、操作维护麻烦、电机装机容量大、备件消耗高的作业环境差、噪声大等缺点。并在泥饼运输过程中,因其含水高达>40%造成二次污染;以及沉淀池中的污水溢
There are 342m ~ 3,302m ~ 3,255m ~ 3 blast furnaces in Hangzhou Iron and Steel Plant, with a total effective volume of 899m ~ 3. Normal production, resulting in blast furnace gas washing sewage 1200m ~ 3 / h, sewage dust concentration of about 1000mg / L, up to 3000 ~ 4000mg / L. The sedimentation tank sediment slurry using a disc vacuum filter for the traditional process of dehydration. Because of this traditional old technology, there are some shortcomings such as complicated process, complicated auxiliary equipment, troublesome operation and maintenance, large motor installed capacity, high spare parts consumption, poor working environment and high noise. And in the mud cake transport process, because of its water up to> 40% caused by secondary pollution; and sewage sediment overflow
