Gelatin wastewater treatment process beneficial to environmental protection
The invention relates to an environment-friendly gelatin wastewater treatment process which is characterized by comprising the following steps: S1, carrying out filter pressing on sludge in a preliminary sedimentation tank through a first filter press, and discharging a mud cake into a batching tank; s2, carrying out filter pressing on the sludge in the adjusting tank through a second filter press, and discharging a mud cake into a batching tank; s3, the wastewater after the flocculation reaction enters a primary sedimentation tank, sludge is subjected to filter pressing through a third filter press, filter pressing tail water enters a standby tank, and a mud cake enters a batching tank; s4, the wastewater enters a secondary sedimentation tank, sludge is subjected to filter pressing through a fourth filter press, filter-pressing tail water enters a standby tank, and a mud cake enters a batching tank; s5, the weight ratio of the mud cake to the coal gangue in the batching pool is 20: 1-25: 1; s6, mold fixing; s7, a first drying section; s8, pricking holes; s9, a second drying section; s10, an anti-cracking working section; and S11, a third drying section. According to the invention, multi-stage precipitation is carried out, precipitated sludge generated by each stage of mud-water separation is effectively utilized, and the environmental protection index of gelatin wastewater treatment is greatly improved.
本发明涉及一种有利于环保的明胶废水处理工艺，其特征在于，包括以下步骤：S1，预沉池内污泥通过第一压滤机进行压滤，泥饼排入配料池；S2，调节池内的污泥通过第二压滤机进行压滤，泥饼排入配料池；S3，絮凝反应后的废水进入初沉池，污泥通过第三压滤机进行压滤，压滤尾水进入备用池，泥饼进入配料池；S4，废水进入二沉池，污泥通过第四压滤机压滤，压滤尾水进入备用池，泥饼进入配料池；S5，配料池中的配料重量比为泥饼：煤矸石=20：1~25：1；S6，定模；S7，第一烘干工段；S8，扎孔；S9，第二烘干工段；S10，防裂工段；S11，第三烘干工段。本发明进行多段沉淀，每段泥水分离产生的沉淀污泥进行有效地利用，大大提高了明胶废水处理的环保指数。
