高速公路服务区生活污水主要以冲厕污水，管理人员及宾客住宿产生的污水、餐饮废水为主，加油站及车辆的清洗废水较少，从而导致了其与城市的常规生活污水虽有类似，却有其自身的特点。
（1）水质变化波动大
由于不同时间车流量、人流量有较大的不同，车辆驶入服务区的随机性又很大，加之季节和节假日的影响，会使得服务区的生活污水进入污水处理设施时有较大的波动性，从而使得污水量的不均对污水处理设施有较强的冲击负荷能力。
（2）浓度更高
冲厕污水显著特点是悬浮物、有机污染物浓度高，对于污水处理的水质指标来说，就是其 COD、氮、磷浓度较高；管理人员及宾客住宿产生的生活污水悬浮物、有机污染物相对较低，利于处理；餐饮废水主要产生的是有机污染物和含油废水，易于生化降解 ；加油站和车辆的清洗废水主要是以颗粒物和石油类为主，难于生化降解。冲厕污水在服务区各类生活污水中占比较大，从而导致服务区污水相比常规生活污水负荷更高。此外，虽然加油站及车辆的清洗废水占比较少，但也会使得服务区污水成分复杂，处理难度更大。
2、中侨启迪高速公路服务区生活污水处理工艺
目前高速公路服务区污水处理工艺有生物接触氧化法、MBR 工艺、AO 工艺、SBR 工艺、人工湿地以及土壤渗滤等，在我国高速公路已建成的服务区中普遍应用的工艺主要有生物接触氧化法 + 沉淀工艺、AO+MBR 工艺等工艺。
（1） 生物接触氧化法+沉淀工艺
生物接触氧化法是从生物膜法派生出来的一种废水生物处理法。通过在曝气池中投加填料，以填料为载体，将微生物附着在填料上，通过曝气使污水与微生物充分接触，从而将污水净化，兼有活性污泥法和生物膜法的特点。沉淀的作用主要是去除水中的悬浮物，一般在高速公路服务区污水处理中，作为生化处理后泥水分离的设施，主要以斜管沉淀池为主。相比传统的活性污泥法，生物接触氧化法具有表面积大、污泥浓度高、污泥龄长、氧利用率高、污泥产量少、运行费用低、设备易操作、易维修等特点，使得其在现阶段高速公路服务区污水处理中，成为最广泛的一种处理技术。但在长期运行过程中，也发现了此组合工艺对污水水量的波动适应性差、耐冲击负荷能力不强，从而导致出水水质不稳定 ；填料易堵塞，且需频繁更换 ；沉淀池受影响因素较多，出水悬浮物较高，影响出水效果。在服务区污水处理中，由于水质中氨氮指标较高，因此一般与厌氧反应（多为水解酸化池）结合使用，通过水解酸化池反硝化以达到去除污水中氨氮的目的，此组合工艺出水水质可达到《污水综合排放标准》（GB8978—1996）一级标准以及更高出水标准。
（2）AO+MBR工艺
AO 工艺也叫缺氧好氧工艺，是生物处理污水的基础工艺，依次由缺氧段和好氧段组成，两阶段分别进行缺氧反硝化和好氧硝化的生化反应过程，并在两阶段之间设置硝化液回流系统，即将好氧池末端的混合液回流至缺氧池前端，从而保证缺氧段的正常脱氮反应，在此过程中，可实现对 COD、BOD 等有机物的降解。MBR 工艺即由一种活性污泥法与膜分离技术相结合的新型水处理技术，将膜分离过程取代传统活性污泥法中的二沉池，从而将泥水分离，可分为中空纤维膜和平板膜两类，膜材质主要为 PVDF。此方法具有占地面积小、污泥浓度高、污泥产量低、耐冲击负荷强、出水水质好的优点，但也存在运维成本高、膜清洗频繁的缺点，同时需对餐饮废水做好除油预处理，以防对后续膜有影响，出水可达到《城市污水再生利用 城市杂用水水质》（GB/T18920—2002）标准以及更高出水标准。

1. Sewage characteristics of the expressway
The domestic sewage in the expressway service area is mainly flushing sewage, sewage and catering wastewater produced by management personnel and guests, and the cleaning wastewater of gas stations and vehicles is less, which leads to the conventional domestic sewage in the city, but it has its own characteristics.
(1) Water quality change fluctuates greatly
Due to different time traffic, traffic has more different, the vehicle into the service area of randomness is very big, combined with the influence of the season and holidays, will make the service area of sewage into the sewage treatment facilities have greater volatility, making the uneven sewage treatment facilities have strong impact load capacity.
(2) Higher concentration
Toilet sewage is characterized by high concentration of suspended matter and organic pollutants, including high concentration of COD, nitrogen and phosphorus for sewage treatment; relatively low suspended matter and organic pollutants produced by management personnel and guest accommodation, which is conducive to treatment; catering wastewater mainly produces organic pollutants and oily wastewater, which is easy to biochemical degradation; cleaning wastewater of gas stations and vehicles is mainly particulate matter and petroleum, which is difficult to biochemical degradation. The flushing sewage accounts for a large proportion of all kinds of domestic sewage in the service area, which leads to a higher load of sewage in the service area compared with the conventional domestic sewage. In addition, although the cleaning wastewater of gas stations and vehicles is relatively small, it will also make the sewage composition in the service area complex and more difficult to treat.
2. Domestic sewage treatment process in the service area of Zhongqi Expressway
At present, the sewage treatment process of expressway service area includes biological contact oxidation method, MBR process, AO process, SBR process, constructed wetland and soil infiltration, etc. The commonly used processes in the service area of expressway in China mainly include biological contact oxidation process + precipitation process, AO + MBR process and other processes.
(1) Biological contact oxidation method + precipitation process
Biological contact oxidation method is a kind of biological treatment method of wastewater derived from the biofilm method. By adding packing in the aeration tank, taking the filler as the carrier, the microorganisms are attached to the filler, and the sewage is fully contacted with the microorganisms through the aeration, so as to purify the sewage, with the characteristics of activated sludge method and biofilm method. The role of precipitation is mainly to remove the suspended solids in the water. Generally, in the sewage treatment of the expressway service area, as a facility for mud and water separation after biochemical treatment, mainly in the inclined tube sedimentation tank. Compared with the traditional activated sludge method, the biological contact oxidation method has the characteristics of large surface area, high sludge concentration, long sludge age, high oxygen utilization rate, low sludge production, low operation cost, easy equipment operation and easy maintenance, which makes it the most extensive treatment technology in the sewage treatment in the service area of the expressway at the present stage. However, in the long-term operation process, it is also found that this combined process has poor adaptability to sewage water fluctuation and weak impact load resistance, thus unstable; the effluent quality is easy to jam and needs to be replaced frequently; the sedimentation tank is more affected by many factors, and the effluent suspended matter is high, which affects the effluent effect. In the service area sewage treatment, because the ammonia nitrogen in the water quality index is higher, so generally with anaerobic reaction (mostly hydrolysis acidification pool), through the hydrolysis acidification pool denitrification to achieve the purpose of removing ammonia nitrogen in sewage, the combination process effluent quality can reach the comprehensive sewage discharge standard (GB8978-1996) level standard and higher water standards.
(2) AO + MBR process
AO process, also called the oxygen aerobic process, is the basis of biological sewage treatment process, in turn, is composed of hypoxia and aerobic section, two stages of hypoxia denitrification and aerobic nitrate biochemical process, and set between the two stages of nitrate liquid reflux system, the aerobic pool mixture at the end of the front, so as to ensure the normal nitrogen of hypoxia reaction, in the process, can realize the degradation of organic matter such as COD, BOD. MBR process is a new water treatment technology combining with the activated sludge process and the membrane separation technology. The membrane separation process replaces the two sedimentation tank in the traditional activated sludge process, so as to separate the muddy water. It can be divided into two categories: hollow fiber membrane and plate film, and the membrane material is mainly PVDF. This method has an area of small, high sludge concentration, low sludge production, strong impact load resistance, good water quality, but also has the disadvantages of high operational cost, membrane cleaning is frequent, at the same time need to catering wastewater oil pretreatment, in case of the subsequent membrane, water can reach the urban sewage recycling urban miscellaneous water quality (GB / T18920-2002) standard and higher water standards.
