牛糞沼液沼渣污泥脫水處理

 簡介

    牛糞沼液沼渣污泥脫水處理屬于螺旋壓榨脫水機，可以減少沉淀池及污泥濃縮池，節(jié)約污水站建設(shè)成本。

    巧妙運用自動更新濾餅過濾技術(shù)代替了傳統(tǒng)濾篩過濾，自身更新濾餅過濾技術(shù)確保脫水機連續(xù)穩(wěn)定的泥水分離效果，通過螺桿直徑和螺距變化產(chǎn)生的強大擠壓力，以及游動環(huán)與固定環(huán)之間的微小縫隙，實現(xiàn)對污泥進(jìn)行擠壓脫水，是一種新型的固液分離設(shè)備。

Multi-Disk Screw Press( Hereinafter referred as MDS ) belongs to the screw press, it's clog-free and can reduce the sedimentation tank and sludge thickening tank, saving the cost of sewage plant construction. MDS using screw and the moving rings to clean itself as clog-free structure, and controlled by the PLC automatically, it's a new technology that can replace the traditional filter press like belt press and frame press, the screw speed is very low, so it cost low power and water consumption in contrast to the centrifuge, it is a cutting edge sludge dewatering machine.

 工藝流程

工藝流程說明

1、通過絮凝實驗，確定匹配的絮凝劑種類和投加比例。如果需要用兩種絮凝劑才能有效絮凝的，建議選擇帶有兩個絮凝混合槽的脫水機。污泥池內(nèi)要設(shè)置攪拌裝置，脫水機在運行之前和運行過程中，要持續(xù)攪拌污泥，保證污泥濃度的相對穩(wěn)定。
2、運行MDS313污泥脫水機之前，應(yīng)先用泡藥裝置泡制好絮凝劑溶液。其中高分子絮凝劑的正常的稀釋倍數(shù)為500-1000倍。污泥通過污泥輸送泵，泡制好的絮凝劑通過加藥泵，按照相應(yīng)的比例同時投加到絮凝混合槽內(nèi)，通過攪拌機進(jìn)行充分混合形成礬花，在濃縮部進(jìn)行重力濃縮，濾液從濃縮部的濾縫中排出。濾液含固量低，直接回流到原水池。
3、濃縮后的污泥沿著螺旋軸向前推進(jìn)，在各種合力的作用下在脫水部充分脫水。脫水部的濾液含固量較高，可回流到絮凝混合槽再次脫水。
4、脫水后的泥餅從泥餅排出口排出，直接或通過無軸螺旋輸送機送至運泥車，進(jìn)行再利用。

Two former digits means the MDS cylinder diameter, the last digit shows the number of the screw shafts, such as MDS 312, it means the MDS cylinder diameter is 310mm, the number of the screw shafts is two.

② Sludge Treatment Capacity=DS Standard Capacity÷Sludge Concentration (DS stands for Dried Sludge, 0% moisture.)

* Throughput of each model is based on sludge cake with 85% water content.

* There is no certain upper limitation on inlet sludge concentration, however, the target sludge must be flowable.

* Throughput of DAF Sludge is based on sludge containing much fat, oil, and grease such as meat processing applications etc.

* Throughput of Mixed Sludge (Primary Sludge and Waste Activated Sludge) and Aerobically Digested Sludge is based on sludge containing more than 30% fiber (200 mesh) against Total Solids.

   運行條件

運行條件

易損品更換時間是個大概數(shù)值，在實際運行過程中，污泥的種類、處理的方式、運行調(diào)整狀況以及每天的運行時間，都會影響易損件的更換周期。（易損件更換周期以365天/年，8小時/天的運行時間來計算。）

Running Conditions

Replacement time of vulnerable part is a estimated time, in the actual operation process, the types of sludge, the means of processing, operation adjustment status and the running of the day, will affect the replacement time. (Replacement cycle of vulnerable part is calculated as 365 days per year, 8 hours/day of running time.)

•   Due to rotation of helical axis, the moving rings begin detaching from the fixed rings while continuously starting the self-cleaning process.  As a result, the ubiquitous clogging is avoided. Therefore, it can handle oily sludge without any trouble while separating the water from the sludge easily. In addition, there is no need to add large quantity of flushing water and there is no odor and no secondary pollution during the dewatering process.

• Multi-Disk Screw Press works by the machine’s internal pressure and needs no large scale integrations like rollers. It saves energy and water and has very minimal noise because of low running speed (2-4 r/min). The average unit power consumption is only 0.1-0.01kwh/kg-DS (1/8 of Belt Press and 1/20 of Centrifuge), and can greatly reduce the running cost of wastewater treatment system.

5) 節(jié)省工程投資
 疊螺污泥脫水機本身具備污泥濃縮功能，直接處理曝氣池內(nèi)好氧污泥，不需要濃縮及貯存單元，減少污水處理設(shè)施整體的占地空間和建設(shè)成本。

• Multi-Disk Screw Press can treat sludge in aeration tank and secondary sedimentation tank without setting sludge thickeners. Therefore, this can decrease the total investment, avoid phosphorus release from the sludge thickeners and sludge storage tanks and enhance phosphorus removal effect of the wastewater treatment system.
• Save construction investments on sludge thickeners and costs on mixers, air compressors, flushing pumps and other auxiliary equipment.
• Occupy smaller space, reducing the construction investment on dewatering room.

 產(chǎn)品比較

 構(gòu)造原理

的主體是由多重固定環(huán)和游動環(huán)構(gòu)成，螺旋軸貫穿其中形成的過濾裝置.前段為濃縮部，后段為脫水部，將污泥的濃縮和壓榨脫水工作在一筒內(nèi)完成，以*微妙的濾體模式取代了傳統(tǒng)的濾布和離心的過濾方式。

Layers of the spacers, which are Fixed and Moving Rings, are secured in place by a tie rod. The inner diameters of the Moving Rings are slightly smaller than the outer diameter of the screw and their rings. Mobilized by the screw, it continuously cleans the sludge out of the gaps, therefore, preventing clogging.

 脫水原理

污泥在濃縮部經(jīng)過重力濃縮后,被運輸?shù)矫撍?在前進(jìn)的過程中隨著濾縫及螺距的逐漸變小,以及背壓板的阻擋作用下,產(chǎn)生*的內(nèi)壓,容積不斷縮小,達(dá)到充分脫水的目的。

The initial section of dewatering drum is the Thickening Zone, where the solid-liquid separating process takes place and where the filtrate will also be discharged. The pitch of the screw and the gaps between the rings decrease at the end of dewatering drum, hence increasing its internal pressure. At the end, the End Plate further increases the pressure, so as to discharge dry sludge cake.
