高速公路服务区污水一体化设备工作原理

厌氧生物滤池简介

1、厌氧生物滤池的作用原理

1）、过滤作用：填料截留过滤进水中的大的颗粒物和悬浮物；

2）、水解作用：厌氧微生物可以将大分子的不溶性的物质水解转化为小分子的可溶性的物质；

3）、吸收作用：厌氧微生物吸附、吸收水中的有机污染物，一部分用于自身的生长繁殖，一部分以沼气的形式通过U型水封出；

4）、脱氮作用：将接触氧化床出水回流至厌氧滤池，厌氧微生物中的反硝化菌可以利用回流水中的硝态氮并将其转化为氮气，以去除污水中的氮物质。

农村污水经厌氧滤池处理后，降低了悬浮物、有机污染物以及氮的浓度，也降低了后续的接触氧化床的负荷。 　2、接触氧化床的作用原理

1）、吸附作用：好氧微生物在填料上生长繁殖过程中相互部结形成表面积较大的、浓度较高的生物膜，可以大量吸附水中大部分的有机污染物，使污染物浓度降低；

2）、摄取、分解作用：在向反应器内不断通空气的情况下，好氧微生物可以将吸附的有机污染物作为营养物质摄体内，进行代谢，一部分用于自身的生长繁殖，一部分转化为二氧化碳和水。

接触氧化床使农村污水中的有机污染物浓度进一步降低，出水CODcr、BOD5去除率达到80%以上，可以达到国家污水排放二级标准。

3、沉淀池的工作原理

1）、利用重力作用使接触氧化床出水中比重大于水的悬浮污泥下沉至池底，从而使之从水中去除，保证较好的出水水质；

2）、沉降至底部的污泥并自动返回至接触氧化床，以维持接触氧化床的污泥浓度。

4、消毒池 通过采用固体氯对出水进行消毒，可有效杀死水中的细菌、大肠杆菌、病毒等致病微生物，处理后的水清亮透明，无臭味，细菌数和大肠杆菌数均可符合国家污水排放标准。

设备特点

高速公路服务区污水一体化设备优点：

地埋式污水处理工艺有多种，在出水达标的前提下，zui突出的优点有：

1.设备埋于地表下，上面可以进行绿化，环境美观。

2.整个设备一般不需要专人管理。

3.可以减少占地面积，设备上方可修建停车场等，无需建厂房等设施。

4.对周围环境无影响、污泥产生量少、噪音小于二类地区的标准。

5.操作简便、工艺新、效果好、使用寿命长。

6.设备可按标准布置，也可随地形需要特殊布置。

缺点：

1.不利于维修.设备出现故障后，不方便检修与更换。这通常是业主zui烦恼的。

2.对环境适应性强，冬天防冻、夏天防洪.北方需要埋入较深，并做保温处理.

什么条件下适合采用高速公路服务区污水一体化设备？

水量较小 、污染物浓度小、成分不复杂、场地有限、需考虑周围环境美化因素等。通常以上几种情况下建议采用地埋式污水处理系统进行处理。

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
