高速公路服務(wù)區(qū)污水一體化設(shè)備工作原理

厭氧生物濾池簡介

1、厭氧生物濾池的作用原理

1）、過濾作用：填料截留過濾進水中的大的顆粒物和懸浮物；

2）、水解作用：厭氧微生物可以將大分子的不溶性的物質(zhì)水解轉(zhuǎn)化為小分子的可溶性的物質(zhì)；

3）、吸收作用：厭氧微生物吸附、吸收水中的有機污染物，一部分用于自身的生長繁殖，一部分以沼氣的形式通過U型水封出；

4）、脫氮作用：將接觸氧化床出水回流至厭氧濾池，厭氧微生物中的反硝化菌可以利用回流水中的硝態(tài)氮并將其轉(zhuǎn)化為氮氣，以去除污水中的氮物質(zhì)。

農(nóng)村污水經(jīng)厭氧濾池處理后，降低了懸浮物、有機污染物以及氮的濃度，也降低了后續(xù)的接觸氧化床的負荷。 　2、接觸氧化床的作用原理

1）、吸附作用：好氧微生物在填料上生長繁殖過程中相互部結(jié)形成表面積較大的、濃度較高的生物膜，可以大量吸附水中大部分的有機污染物，使污染物濃度降低；

2）、攝取、分解作用：在向反應(yīng)器內(nèi)不斷通空氣的情況下，好氧微生物可以將吸附的有機污染物作為營養(yǎng)物質(zhì)攝體內(nèi)，進行代謝，一部分用于自身的生長繁殖，一部分轉(zhuǎn)化為二氧化碳和水。

接觸氧化床使農(nóng)村污水中的有機污染物濃度進一步降低，出水CODcr、BOD5去除率達到80%以上，可以達到國家污水排放二級標準。

3、沉淀池的工作原理

1）、利用重力作用使接觸氧化床出水中比重大于水的懸浮污泥下沉至池底，從而使之從水中去除，保證較好的出水水質(zhì)；

2）、沉降至底部的污泥并自動返回至接觸氧化床，以維持接觸氧化床的污泥濃度。

4、消毒池 通過采用固體氯對出水進行消毒，可有效殺死水中的細菌、大腸桿菌、病毒等致病微生物，處理后的水清亮透明，無臭味，細菌數(shù)和大腸桿菌數(shù)均可符合國家污水排放標準。

設(shè)備特點

高速公路服務(wù)區(qū)污水一體化設(shè)備優(yōu)點：

地埋式污水處理工藝有多種，在出水達標的前提下，zui突出的優(yōu)點有：

1.設(shè)備埋于地表下，上面可以進行綠化，環(huán)境美觀。

2.整個設(shè)備一般不需要專人管理。

3.可以減少占地面積，設(shè)備上方可修建停車場等，無需建廠房等設(shè)施。

4.對周圍環(huán)境無影響、污泥產(chǎn)生量少、噪音小于二類地區(qū)的標準。

5.操作簡便、工藝新、效果好、使用壽命長。

6.設(shè)備可按標準布置，也可隨地形需要特殊布置。

缺點：

1.不利于維修.設(shè)備出現(xiàn)故障后，不方便檢修與更換。這通常是業(yè)主zui煩惱的。

2.對環(huán)境適應(yīng)性強，冬天防凍、夏天防洪.北方需要埋入較深，并做保溫處理.

什么條件下適合采用高速公路服務(wù)區(qū)污水一體化設(shè)備？

水量較小 、污染物濃度小、成分不復(fù)雜、場地有限、需考慮周圍環(huán)境美化因素等。通常以上幾種情況下建議采用地埋式污水處理系統(tǒng)進行處理。

1. Select and appoint engineering technicians and workers who are professionally

competent and personally committed to undertake the after-sale service work. Meanwhile set up the service office made up of chief engineer office, project office, technical center, after-sale service department and workshop specialists led and coordinated by marketing and sales department.

2. During the Valin ArcelorMittal Automotive Steel Co.,Ltd Crane in Main Factory

Building of Cold Rolling Project on-site installation and trial un, appoint specialized after-sale service personnel to work at the work place
