廢水首先進入調(diào)節(jié)池調(diào)節(jié)水量，通過加入絮凝劑混合，使廢水中的細小懸浮物聚集成較大的礬花，再進入高效沉淀池，使大部分懸浮物沉淀，沉淀下的污泥通過重力作用由排泥管排至污泥池，上清液溢流至氧化池，在氧化池中通過投加酸調(diào)節(jié)PH值為略酸性，再投加氧化劑，氧化大部分的苯類、有機酸等化和物，降低CODCr，氧化后的廢水經(jīng)活性炭過濾器過濾，吸附剩余的苯類、酯、有機酸等，過濾懸浮物，保證出水達標排放。
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.
污泥池上液溢流回調(diào)節(jié)池，由于廢水量小，產(chǎn)生的污泥量小，污泥定時用壓濾機壓濾排泥。氧化劑使用Fenton 試劑從1894 年H. J . H. Fenton 發(fā)現(xiàn)了Fenton 試劑以來,Fenton 試劑在工業(yè)廢水處理方面得到了廣泛地應(yīng)用,它具有極強的氧化能力,對生物降解或一般化學氧化劑難以奏效的有機廢水有較好的處理效果。Fenton 試劑的作用機理如下:
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-
Fe2 + + H2O2 ——Fe3 + + OH·+ OH-
Fe3 + + H2O2—— Fe2 + + HO2·+ H+

5.1 high efficiency sedimentation tank
濟南特瑞興環(huán)保在高效沉淀池入水中投加絮凝劑，使水中難溶難沉淀的物質(zhì)互相聚合，長大至能自然沉淀的程度。絮凝處理中包括凝聚和絮凝兩個階段。在凝聚階段，在絮凝劑的作用下，水中的膠體雙層被壓縮失去穩(wěn)定而形成較小的顆粒，在絮凝階段，在助凝劑的吸附架橋作用下這些微?；ハ嗑劢Y(jié)，形成大顆粒絮體，滿足后續(xù)沉淀處理條件。
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.
廢水中的懸浮物質(zhì)，可在重力作用下沉淀去除。這是一種物理過程，簡便易行，效果良好，是污水處理的重要技術(shù)之一。根據(jù)懸浮物的性質(zhì)、濃度及絮凝性能，沉淀可分為4種類型：自由沉淀、絮凝沉淀、成層沉淀和壓縮沉淀。沉淀池可分為平流式沉淀池、輻流式沉淀池、豎流式沉淀池和斜板(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.
