废水进入调节池调节水量，通过加入絮凝剂混合，使废水中的细小悬浮物聚集成较大的矾花，再进入沉淀池，使大部分悬浮物沉淀，沉淀下的污泥通过重力作用由排泥管排污泥池，上清液溢流氧化池，在氧化池中通过投加酸调节PH值为略酸性，再投加氧化剂，氧化大部分的苯类、有机酸等化和物，降低CODCr，氧化后的废水经活性炭过滤器过滤，吸附剩余的苯类、酯、有机酸等，过滤悬浮物，保证出水达标排放。
The wastewater first enters into the regulating tank to regulate the water volume. By adding flocculant to mix, the fine suspended solids in the wastewater are aggregated into large alum flowers. Then it enters into the high-efficiency sedimentation tank to precipitate most of the suspended solids. The sludge under the sedimentation is discharged from the sludge discharge pipe to the sludge tank by gravity, and the supernatant overflows to the oxidation tank. In the oxidation tank, the pH value is adjusted to slightly acidic by adding acid, Then the oxidant is added to oxidize most of benzene, organic acid and other chemicals to reduce CODcr. The oxidized wastewater is filtered by activated carbon filter to absorb the remaining benzene, ester, organic acid and so on, and the suspended solids are filtered to ensure the effluent discharge up to the standard.
污泥池上液溢流回调节池，由于废水量小，产生的污泥量小，污泥定时用压滤机压滤排泥。氧化剂使用Fenton 试剂从1894 年H. J . H. Fenton 发现了Fenton 试剂以来,Fenton 试剂在工业废水处理方面得到了广泛地应用,它具有极强的氧化能力,对生物降解或一般化学氧化剂难以奏效的有机废水有较好的处理效果。Fenton 试剂的作用机理如下:
The overflow of the sludge tank is called back to the saving tank. Due to the small amount of waste water, the amount of sludge produced is small, and the sludge is regularly filtered and discharged by the filter press. Fenton reagent is used as oxidant. Since h. J. h. Fenton discovered Fenton reagent in 1894, Fenton reagent has been widely used in industrial wastewater treatment. It has strong oxidation ability, and has good treatment effect for organic wastewater which is difficult to be treated by biodegradation or general chemical oxidant. The mechanism of Fenton reagent is as follows
Fe2 + + H2O2 ——Fe3 + + OH·+ OH-

Fe3 + + H2O2—— Fe2 + + HO2·+ H+

5.1 high efficiency sedimentation tank
济南特瑞兴环保在沉淀池入水中投加絮凝剂，使水中难溶难沉淀的物质互相聚合，长大能自然沉淀的程度。絮凝处理中包括凝聚和絮凝两个阶段。在凝聚阶段，在絮凝剂的作用下，水中的胶体双层被压缩失去稳定而形成较小的颗粒，在絮凝阶段，在助凝剂的吸附架桥作用下这些微粒互相聚结，形成大颗粒絮体，满足后续沉淀处理条件。
Jinan terexing environmental protection Co., Ltd. adds flocculant into the water of high-efficiency sedimentation tank to make the insoluble and difficult to precipitate substances in the water polymerize with each other and grow up to the degree of natural precipitation. Flocculation treatment includes coagulation and flocculation. In the coagulation stage, under the action of flocculant, the colloidal double layers in water are compressed and lose stability to form smaller particles. In the flocculation stage, under the action of adsorption bridging of coagulant aid, these particles agglomerate with each other to form large particle flocs, which can meet the conditions of subsequent precipitation treatment.
废水中的悬浮物质，可在重力作用下沉淀去除。这是一种物理过程，简便易行，效果良好，是污水处理的重要技术之一。根据悬浮物的性质、浓度及絮凝性能，沉淀可分为4种类型：自由沉淀、絮凝沉淀、成层沉淀和压缩沉淀。沉淀池可分为平流式沉淀池、辐流式沉淀池、竖流式沉淀池和斜板(管)沉淀池。
The suspended matter in wastewater can be removed by precipitation under the action of gravity. This is a physical process, simple and easy to operate, good effect, is one of the important technologies of sewage treatment. According to the properties, concentration and flocculation performance of suspended solids, the precipitation can be divided into four types: free precipitation, flocculation precipitation, layered precipitation and compression precipitation. The sedimentation tank can be divided into horizontal sedimentation tank, radial sedimentation tank, vertical sedimentation tank and inclined plate (tube) sedimentation tank.
