摘要：【中文】本发明公开了一种河湖底泥板框压滤脱水方法，河湖底泥泥浆经除渣后进入输泥管线，与絮凝剂混合后进入浓缩池进行泥水分离，上清液浊度满足要求后输送至余水处理系统；泥浆达到一定浓度后进入搅拌罐，加入助滤剂，充分搅拌；充分反应后，泥浆进入板框压滤机，压滤脱水完成后，通入压缩空气清理压滤槽，然后卸除泥饼，尾水输送回浓缩池。本发明的助滤剂是环保型助滤底泥调理剂，可有效加速泥水分离，不影响泥水的pH值，大幅降低调理剂投加量，经泥水分离后的底泥可用于回填土或绿化种植土，实现河湖底泥的资源化和可持续利用；另外，由空压机通入压缩空气清理管道，空压机在提供压力的基础上增加了辅助清理压滤槽的功能，充分利用已有设备和能源。 【EN】The invention discloses a plate-frame filter-pressing dehydration method for river and lake bottom mud, which comprises the steps of deslagging river and lake bottom mud, then feeding the sludge into a mud conveying pipeline, mixing the sludge with a flocculating agent, then feeding the sludge into a concentration tank for sludge-water separation, and conveying supernatant to a residual water treatment system after the turbidity meets the requirement; after the slurry reaches a certain concentration, the slurry enters a stirring tank, and a filter aid is added and fully stirred; after full reaction, the slurry enters a plate-and-frame filter press, compressed air is introduced to clean a filter press tank after filter pressing and dehydration are finished, then mud cakes are removed, and tail water is conveyed back to a concentration tank. The filter aid is an environment-friendly filter-aid bottom mud conditioner, can effectively accelerate mud-water separation, does not influence the pH value of mud and water, greatly reduces the dosage of the conditioner, and can be used for backfilling soil or planting green soil after mud-water separation, thereby realizing the resource and sustainable utilization of river and lake bottom mud; in addition, the compressed air is introduced into the cleaning pipeline through the air compressor, the air compressor is additionally provided with the function of auxiliary cleaning of the filter pressing tank on the basis of providing pressure, and the existing equipment and energy are fully utilized.
