随着全球人口激增，小区居住人口越来越多，小区是具有一种或多种功能的相对独立的区域，包括通常意义上的居民生活小区、医院、公园、旅游渡假村、新建大学城、高速公路的生活服务区等，其排水系统通常不在城市市政管网覆盖范围之内，必须设置独立的污水处理设施。很多国家为了解决小区污水处理难题，会从我国购买外贸生活污水处理设备，下面中侨启迪小编带您了解一下该设备。
小区生活污水不同于包括部分工业废水的城市污水，其水质水量特征为:水质、水量小时变化系数较大，污染物浓度通常比城市污水低，污水可生化性好，处理难度较小;且由于其污染来源比较简单，从处理技术和处理成本角度考虑，具有相当的技术可行性和很高的回用价值。
资料显示，以生活用水为例，用于烹饪、饮用的水约占5 %，而对占20 %～30 %不与人体直接接触的生活杂用水如冲厕用水等，加上小区绿化浇灌用水、空调冷却水、地面冲洗水以及车辆清洗等用水也可归入生活杂用水的范畴，并无高水质要求，这种用水分布为小区生活污水的回用去向提供了可能。
根据小区的功能特点，外贸生活污水处理设备处理后的水回用方向，主要应该是厕所冲洗水、绿化浇灌水、地面冲洗水、车辆冲洗水、非接触风景景观用水等。一般要求小区生活污水经过外贸生活污水处理设备处理并消毒后，使回用水水质达到标准，即可满足对于小区生活污水的一般回用要求。
外贸生活污水处理设备的意义是非常重大的，与远距离调水相比，生活污水再生利用更经济，且更容易保证输水水质。远距离输水系统的建设以及建成后的运行都是耗资巨大的工程。同时如何保护和保持远距离输水的水质和水量也是当前和今后很长时间都必须面对的问题。
并且与无限制的开采地下水相比，城市污水的再生利用更容易保护可用的水资源。地下水的过度开采能导致水位的大幅度下降，形成大面积的漏斗区，从而使许多水井枯竭、草木枯萎，严重破坏地面生态环境，尤其是沿海地区可能因海水的入侵而严重污染地下水资源。而在保证水质的情况下，使用再生水进行地下水回灌有助于提升地下水位，防止各类事故的发生。所以外贸生活污水处理设备的意义显得十分重大。

With the global population surge, the residential population of the community is increasing. The community is a relatively independent area with one or more functions, including residential living quarters, hospitals, parks, tourist resort villages, Newly-built University City, expressway living service areas, etc. its drainage system is usually not covered by the urban municipal pipe network, and independent sewage treatment facilities must be set. In order to solve the problem of community sewage treatment, many countries will buy domestic sewage treatment equipment for foreign trade from China. The following overseas Chinese enlighten Xiaobian to take you to know about the equipment.
Residential domestic sewage is different from urban sewage including some industrial wastewater. Its water quality and quantity characteristics are as follows: the hourly variation coefficient of water quality and quantity is large, the pollutant concentration is usually lower than that of urban sewage, the biodegradability of sewage is good, and the treatment difficulty is small; And because its pollution source is relatively simple, it has considerable technical feasibility and high reuse value from the perspective of treatment technology and treatment cost.
Data show that taking domestic water as an example, about 5% of the water is used for cooking and drinking, while 20% ~ 30% of the domestic miscellaneous water that does not come into direct contact with the human body, such as toilet flushing water, together with the water for greening and irrigation, air conditioning cooling water, ground flushing water and vehicle cleaning, can also be classified into the category of domestic miscellaneous water. There is no high water quality requirement. This water distribution provides the possibility for the reuse of domestic sewage in the community.
According to the functional characteristics of the community, the water reuse direction after treatment by foreign trade domestic sewage treatment equipment should mainly be toilet flushing water, greening irrigation, ground flushing water, vehicle flushing water, non-contact landscape water, etc. It is generally required that the domestic sewage of the community can meet the general reuse requirements of the domestic sewage of the community after being treated and disinfected by the domestic sewage treatment equipment of foreign trade to make the reuse water quality meet the standard.
The significance of domestic sewage treatment equipment in foreign trade is very significant. Compared with long-distance water transfer, domestic sewage recycling is more economical and easier to ensure the water quality. The construction of long-distance water conveyance system and its operation after completion are expensive projects. At the same time, how to protect and maintain the water quality and quantity of long-distance water transmission is also a problem that must be faced at present and for a long time in the future.
And compared with the unrestricted exploitation of groundwater, the recycling of urban sewage is easier to protect the available water resources. Overexploitation of groundwater can lead to a significant decline in water level and the formation of a large area of funnel area, resulting in the depletion of many wells, the withering of plants and trees, and the serious damage to the ground ecological environment, especially in coastal areas, which may seriously pollute groundwater resources due to the invasion of seawater. Under the condition of ensuring the water quality, the use of reclaimed water for groundwater reinjection will help to raise the groundwater level and prevent various accidents. Therefore, the significance of domestic sewage treatment equipment in foreign trade is very great.
The above is the information about foreign trade domestic sewage treatment equipment compiled by Zhongqiao enlightenment Xiaobian for you. If you want to buy foreign trade domestic sewage treatment equipment, you can contact our customer service staff and look forward to cooperating with you
