The invention discloses a commercial concrete mixing plant transport tanker cleaning and station yard sewage purification system. Sewage at the cleaning position of the tank truck enters the sand-stone separator through a pipeline; the sand-stone separator is used for separating sewage for cleaning the tank truck into sand-stone and muddy water; muddy water and station yard sewage enter a solid-liquid separation pit through a pipeline; a dewatering bucket elevator in the solid-liquid separation pit conveys underflow sediment in the solid-liquid separation pit back to the sand-stone separator for separation again; overflowing liquid around the top of the solid-liquid separation pit enters a buffer pool; a stirring device in the buffer pool is used for stirring the slurry in the buffer pool;a part of the slurry is properly shunted to a mixing plant through a pipeline to be recycled and the rest slurry enters the stirring barrel through a pipeline, meanwhile, the other part enters a stirring barrel through a pipeline, wherein an automatic dosing machine is arranged on the stirring barrel; a mixed solution in the stirring barrel enters a full-automatic filter press through a pipelineto generate a filter cake and a filtrate, wherein the filtrate enters a circulating water tank through a pipeline, and regenerated circulating water in the circulating water tank returns to a tank carcleaning position through a pipeline and is used for tank car cleaning again. The system is simple in structure, reliable in process, easy to control, efficient and environmentally friendly.

    本发明公开了一种商品混凝土搅拌站运输罐车清洗及站场污水净化系统,罐车清洗处的污水通过管路进入砂石分离机,砂石分离机将罐车清洗的污水分为砂石和泥水,泥水和站场污水通过管路进入捞坑,捞坑中的脱水斗式提升机将捞坑中的底流沉淀物输送回砂石分离机重新进行分离,捞坑顶部四周溢流进入缓冲池,缓冲池中的搅拌装置对其中的泥浆进行搅拌,酌情将一部分泥浆通过管路分流至搅拌楼回用,其余泥浆通过管路进入搅拌桶,另一路通过管路进入搅拌桶,搅拌桶上设置有自动加药机,搅拌桶内的混合液通过管路进入全自动压滤机产生滤饼和滤液,滤液通过管路进入循环水池,循环水池中的再生循环水通过管路回到罐车清洗处,再次用于罐车清洗;本发明结构简单、工艺可靠、易于管控、且高效环保。
