生活污水是人类在日常生活中使用过的，并被生活废料所污染的水。其水质、水量随季节而变化，一般夏季用水相对较多，浓度低；冬季相应量少，浓度高。生活污水一般不含有毒物质，但是它有适合微生物繁殖的条件，含有大量的病原体，从卫生角度来看有一定的危害性。

城市每人每日排出的生活污水量为150—400L，其量与生活水平有密切关系。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。

城市污染源是因城市人口集中，城市生活污水、垃圾和废气引起水体污染造成的。城市污染源对水体的污染主要是生活污水，它是人们日常生活中产生的各种污水的混合液，其中包括厨房、洗涤房、浴室和厕所排出的污水。
世界上仅城市地区一年排出的工业和生活废水就多达500立方公里，而每一滴污水将污染数倍乃至数十倍的水体

Domestic sewage is the water that is used in daily life and is polluted by the living waste. The water quality and water quantity vary with the season. In general, the water use in summer is relatively more, the concentration is low, and the corresponding quantity in winter is less and the concentration is high. Domestic sewage generally does not contain toxic substances, but it has conditions suitable for microbial propagation, and contains a large number of pathogens, which is harmful from a hygienic perspective.

The daily discharge of domestic sewage per person in the city is 150 - 400L, and the amount of sewage is closely related to the living standard. Domestic sewage contains a lot of organic matter, such as cellulose, starch, sugar and fat protein. It also contains pathogenic bacteria, viruses and parasitic eggs. Inorganic salts such as chloride, sulfate, phosphate, bicarbonate and sodium, potassium, calcium, magnesium and so on. The total characteristics are nitrogen, sulphur and phosphorus. Under the action of anaerobic bacteria, it is easy to produce malodorous substances.

The source of urban pollution is due to the concentration of urban population, and the pollution caused by municipal sewage, waste and waste gas. The pollution of urban pollution sources is mainly domestic sewage. It is a mixture of various sewage produced in people's daily life, including sewage discharged from kitchen, washing room, bathroom and toilet.

In the world, only 500 cubic kilometers of waste water from industrial and living waste are discharged in one year, and every drop of sewage will be polluted by several times or even dozens of times of water.

My company with foreign advanced technology, the production of underground integrated sewage treatment equipment, in the sewage out of the water, sewage purification equipment before seepage, long duration, corrosion Water Leakage phenomenon, our company production of sewage treatment equipment with corrosion protection technology of glass steel, using solar water purification. With the advantages of environmental protection, energy saving and low carbon, it has won the same high praise from the industry. It is a high-tech sewage treatment product of new countryside construction, optimization of urban and rural structure and energy conservation.
