人们生活过程中产生的污水，是全世界水体的主要污染源之一，主要是粪便和洗涤污水。如果不经过处理，将会对人类赖以生存的环境造成很大的危害。很多国家都从我国购买出口生活污水处理设备帮助他们解决生活污水处理难题，下面中侨启迪小编带您了解一下此设备。
 
        生活污水中含有大量有机物，如纤维素、淀粉、糖类和脂肪蛋白质等；也常含有病原菌、病毒和寄生虫卵；无机盐类的氯化物、硫酸盐、磷酸盐、碳酸氢盐和钠、钾、钙、镁等。总的特点是含氮、含硫和含磷高,在厌氧细菌作用下，易生恶臭物质。
 

 
        出口生活污水处理设备采用常规的“调节池+A/A/O生物接触氧化+沉淀+MBR膜+清水池+消毒”工艺，该处理工艺较为简单，操作运行方便，日常费用低廉，出水稳定，主要设备为钢结构，考虑到周边环境和卫生问题，故该污水处理工程决定采用全埋地式结构，上部覆土，种植花木、草坪，进一步美化环境。
 
        出口生活污水处理设备去除有机污染物及氨氮主要依赖于设备中的AO生物处理工艺。其中工作原理是在A级，由于污水有机物浓度很高，微生物处于缺氧状态，此时微生物为兼性微生物，所以A级池不仅具有一定的有机物去除功能，减轻后续好氧池的有机负荷，有机物浓度降低，但仍有一定量的有机物及较高NH3-N存在。
 

 
        为了使有机物得到进一步氧化分解，同时在碳化作用下硝化作用能顺利进行，在O级设置有机负荷较低的好氧生物接触氧化池。在O级池中主要存在好氧微生物及自氧型细菌（硝化菌）。其中好氧微生物将有机物分解成CO2和H2O；自养型细菌（硝化菌）利用有机物分解产生的无机碳或空气中的CO2作为营养源，将污水中的NH3-N转化成NO-2-N、NO-3-N，O级池的出水部分回流到A级池，为A级池提供电子接受体，通过反硝化作用最终消除氮污染。
 
        出口生活污水处理设备的适用范围
 
        1、美丽乡村、乡镇、农村生活污水处理
 
        2、厂区、矿区生活污水处理
 
        3、高速服务区、风景区生活污水处理
 
        4、养老院污水处理
 
        5、公厕污水处理

      Sewage produced in the process of people's life is one of the main pollution sources of water bodies in the world, mainly feces and washing sewage. If not treated, it will cause great harm to the environment on which human beings live. Many countries have purchased and exported domestic sewage treatment equipment from my country to help them solve the problem of domestic sewage treatment.
 
      Domestic sewage contains a large amount of organic matter, such as cellulose, starch, carbohydrates and fatty proteins; it also often contains pathogenic bacteria, viruses and parasite eggs; inorganic salts such as chloride, sulfate, phosphate, bicarbonate and sodium, Potassium, calcium, magnesium, etc. The general feature is that it contains high nitrogen, sulfur and phosphorus content, and is prone to odorous substances under the action of anaerobic bacteria.
 
      The export domestic sewage treatment equipment adopts the conventional process of "regulating tank + A/A/O biological contact oxidation + precipitation + MBR membrane + clear water tank + disinfection". The main equipment is steel structure. Considering the surrounding environment and sanitation issues, the sewage treatment project decided to adopt a fully buried structure, the upper part is covered with soil, and flowers, trees and lawns are planted to further beautify the environment.
 
      The removal of organic pollutants and ammonia nitrogen by export domestic sewage treatment equipment mainly relies on the AO biological treatment process in the equipment. The working principle is in the A-level. Due to the high concentration of organic matter in the sewage, the microorganisms are in an anoxic state. At this time, the microorganisms are facultative microorganisms. Therefore, the A-level pool not only has a certain function of removing organic matter, but also reduces the organic load of the subsequent aerobic pool. The organic matter concentration decreased, but a certain amount of organic matter and higher NH3-N still existed.
 
      In order to further oxidatively decompose the organic matter, and at the same time, the nitrification can proceed smoothly under the action of carbonization, an aerobic biological contact oxidation tank with low organic load is set up at the O level. There are mainly aerobic microorganisms and autoxic bacteria (nitrifying bacteria) in the O-level pool. Among them, aerobic microorganisms decompose organic matter into CO2 and H2O; autotrophic bacteria (nitrifying bacteria) use the inorganic carbon produced by the decomposition of organic matter or CO2 in the air as a nutrient source to convert NH3-N in sewage into NO-2-N , NO-3-N, the effluent part of the O-level pool is returned to the A-level pool to provide electron acceptors for the A-level pool, and finally eliminate nitrogen pollution through denitrification.
 
      Scope of application of export domestic sewage treatment equipment
 
      1. Domestic sewage treatment in beautiful villages, towns and rural areas
 
      2. Domestic sewage treatment in factories and mining areas
 
      3. Domestic sewage treatment in high-speed service areas and scenic areas
 
      4. Sewage treatment in nursing homes
 
      5. Public toilet sewage treatment
