Inorganic constituents The common inorganic constituents of wastewater include:
1.Chorides and sulphates. Normally persent in water and in wastes from humans.
2.Nitrogen and phosphorous. In their various forms (organic and inorganic) in wastes from human,with additional phosphorous from detergents.
3.Carbonates and bicarbonate. Normally present in water and wastes as calcium and magnesium salts.
4.toxic substances.Arsenic,cyanide,and heavy metals such as Cd,Cr,Cu,Hg,Pb,and Zn are toxic inorganics which may be found in industrial wastes.
In addition to these chemical constituents.The concentration of dissolved gases,especially oxygen,and the hydrogen ion concentration expressed as PH are other parameters of interest in wastewater.
Organic mattetr Proteins and carbohydrates constitute 90 percent of the organic matter in domestic sewage. The sources of these biodegradable contaminants include excreta and urine from humans;food wastes from sinks, soil and dirt from bathing ,washing,and laundering,plundering, plus various soaps,detergents, and other cleaning products.

废水中的普通无机物成分包括：
1、草酸和硫酸盐。一般情况下存在水中和人类的废物中。
2、氮和磷。以不同的状态（有机物和无机物）存在于人类的废弃物中和添加磷的洗涤剂中。
3、碳酸盐和碳酸氢盐。一般情况下在水及钙和镁药用盐的废物中。
4、有毒物质砷、氰化物和重金属物质，像铬、铜、汞、铅和锌是有毒物质，这些可能在工业垃圾中发现。
除了这些化学成分外，有毒气体也是值得关注的，特别是氧和氢离子用PH值表示，是废水的另一个参数。
有机物蛋白质和碳水化合物在国内污水中占有机物的90%，这些能降解的污染物来源包括在人类的排泄物和尿液中，洗涤池中的废弃物中，泥土和洗澡时的污物，洗涤脏的物品和各种洗涤剂还有其它清洁用品中。
