I. Project Background and Objectives The coal chemical industry generates a large amount of wastewater in its production process, which contains high concentrations of inorganic salts, organic matter, ammonia nitrogen and other pollutants, posing a serious threat to the environment. In order to achieve clean production and environmental protection, a
What’s the types of sludge? Sludge is a heterogeneous body composed of organic debris, bacteria, inorganic particles and colloids. It is difficult to separate solids and liquids thoroughly through sedimentation. The sludge produced by sewage treatment is a typical organic sludge, which is characterized by high organic content (60%~80%), fine
The carbon source used in water treatment is generally considered to be a carbon-containing element that is easily utilized by microorganisms and promotes the growth of microorganisms. It is a carbon-containing organic matter with a short carbon chain and a simple molecular structure. For example: monosaccharides, polysaccharides, oils and fats,
