20世纪50年代以后，全球人口急剧增长，工业发展迅速。全球水资源状况迅速恶化，“水危机”日趋严重。一方面，人类对水资源的需求以惊人的速度扩大；另一方面，日益严重的水污染蚕食大量可供消费的水资源。不管在哪个国家，水资源都是非常重要的，如果能将污水处理后循环利用，国家的水资源就得以可持续发展，所以从目前来看污水处理设备出口行情是非常乐观的，下面中侨启迪小编就带您详细了解。
 
       城市污水处理技术就是利用各种设施设备和工艺技术，将污水所含的污染物质从水中分离去除，使有害的物质转化为无害的物质、有用的物质，水则得到净化，并使资源得到充分利用。
城市污水处理技术通常有物理处理技术、化学处理技术、物理化学处理技术、生物处理技术等。
 
       典型的物理处理技术在城市污水处理中应用的有沉淀技术、过滤技术、气浮技术等。典型的化学处理技术和物理化学处理技术有中和、加药混凝、离子交换等。典型的生物处理技术有好氧牲氧化分解和厌氧生物发酵技术。城市污水处理工艺，实际上是以上这些技术的应用与组合。城市污水处理工艺：城市污水处理工艺按流程和处理程序划分，可分为预处理工艺，一级处理工艺、二级处理工艺、深度处理工艺和污泥处理工艺，以及最终的污泥处置。
 
       目前来看除了发达国家以外，很多国家的污水处理行业发展缓慢，而中国所制造的污水处理设备精良，出水效果好，是很多国家购买设备的首选，所以污水处理设备出口行情目前是非常乐观的，如果您想要购买污水处理设备出口，可以联系中侨启迪的客服工作人员，期待与您的合作！
 

 
       After the 1950s, the global population increased rapidly and industry developed rapidly. The situation of global water resources is deteriorating rapidly, and the "water crisis" is becoming more and more serious. On the one hand, human demand for water resources is expanding at an alarming rate; On the other hand, the increasingly serious water pollution has eroded a large number of water resources available for consumption. No matter in which country, water resources are very important. If the sewage can be recycled after treatment, the country's water resources will be able to develop sustainably. Therefore, at present, the export market of sewage treatment equipment is very optimistic. The following Chinese overseas Chinese enlightenment series will take you to know in detail.

       Urban sewage treatment technology is to separate and remove the pollutants contained in sewage from water by using various facilities, equipment and technology, so as to convert harmful substances into harmless and useful substances, purify water and make full use of resources.Urban sewage treatment technology usually includes physical treatment technology, chemical treatment technology, physical and chemical treatment technology, biological treatment technology and so on.

       Typical physical treatment technologies used in urban sewage treatment include sedimentation technology, filtration technology, air flotation technology and so on. Typical chemical treatment technologies and physicochemical treatment technologies include neutralization, dosing coagulation, ion exchange, etc. Typical biological treatment technologies include aerobic animal oxidative decomposition and anaerobic biological fermentation. Urban sewage treatment process is actually the application and combination of these technologies. Urban sewage treatment process: urban sewage treatment process can be divided into pretreatment process, primary treatment process, secondary treatment process, advanced treatment process, sludge treatment process and final sludge disposal according to process flow and treatment procedure.

       At present, in addition to developed countries, the sewage treatment industry in many countries is developing slowly, while the sewage treatment equipment made in China is excellent and the effluent effect is good, which is the first choice for many countries to buy equipment, so the export market of sewage treatment equipment is very optimistic. If you want to buy the export of sewage treatment equipment, you can contact the customer service staff of overseas Chinese enlightenment and look forward to cooperating with you!
