Municipal sewage treatment plant sludge resource utilization method
The invention discloses a municipal sewage treatment plant sludge resource utilization method which comprises the following steps: S1, carrying out two-time gravity concentration on municipal sewage treatment plant sludge to obtain a supernatant liquid and a lower layer concentrated sludge, storing the supernatant liquid in a supernatant liquid tank, and storing the concentrated sludge in a sludge tank; s2, adding sodium lignin sulfonate and fatty alcohol-polyoxyethylene ether into the sludge tank, and uniformly mixing to obtain a liquid sludge raw material; s3, mixing coal gangue and shale according to a certain proportion, crushing, and screening to obtain a brick making raw material; s4, adding the liquid sludge raw material into the brick making raw material, mixing to obtain pug, and feeding the pug into an aging warehouse for aging to obtain an aged material; s5, adding water into the aged material, mixing, stirring, and extruding into blank strips through a vacuum brick extruding machine; and S6, cutting the blank strips into green bricks, drying, sintering and making the bricks. According to the method, the clear liquid and the concentrated sludge obtained from the sludge of the municipal sewage treatment plant can be fully utilized, and economic and environment-friendly treatment and resource utilization of the sludge are realized.
本发明公开了一种城镇污水处理厂污泥资源化利用方法，包括以下步骤：S1、对城镇污水处理厂污泥进行两次重力浓缩，得上层清液和下层浓缩污泥，清液储存于清液罐，浓缩污泥储存于污泥罐；S2、所述污泥罐中加入木质素磺酸钠、脂肪醇聚氧乙烯醚，混合均匀，得液态污泥原料；S3、将煤矸石、页岩按一定比例混合、破碎、筛分，得制砖原料；S4、所述制砖原料中加入所述液态污泥原料，混合，得泥料，将泥料送入陈化库陈化，得陈化料；S5、所述陈化料加水、混合、搅拌，经真空挤砖机挤压成坯条；S6、将所述坯条切成砖坯，干燥，烧结，制砖。本发明能够充分利用城镇污水处理厂污泥得到的清液和浓缩污泥，实现污泥的经济、环保处理处置及资源化利用。
