Environment-friendly wastewater treatment process of fish skin gelatin
The invention relates to an environment-friendly wastewater treatment process for fish skin gelatin. The environment-friendly wastewater treatment process comprises the following steps: S1, carrying out filter pressing on sludge in a pre-sedimentation tank through a first filter press; s2, carrying out filter pressing on the sludge in the adjusting tank through a second filter press; s3, the wastewater subjected to the flocculation reaction enters a primary sedimentation tank, a mixed flocculant comprises FeSO4, PAC and PAM according to the ratio of 100: (10-20): (10-20), sludge is subjected to filter pressing through a third filter press, and filter pressing tail water enters a standby 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 mud cakes subjected to filter pressing through the filter presses all enter 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, and the generated precipitated sludge is intensively and effectively utilized, so that the environmental protection index of gelatin wastewater treatment is improved while economic benefits are generated.
本发明涉及一种鱼皮明胶的环保型废水处理工艺，包括以下步骤：S1，预沉池内污泥通过第一压滤机进行压滤；S2，调节池内的污泥通过第二压滤机进行压滤；S3，絮凝反应后的废水进入初沉池，混合絮凝剂包括FeSO4、PAC和PAM为100:(10～20):(10～20)，污泥通过第三压滤机进行压滤，压滤尾水进入备用池；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，上述压滤机压滤的泥饼均进入配料池；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，产生的沉淀污泥进行集中有效地利用，产生经济效益的同时，提高了明胶废水处理的环保指数。
