环境工程学（Environmental Engineering） Municipal solid waste treatment: crushing, compacting and sorting To improve the three principles of solid waste reduction, recycling and harmless Factors affecting anaerobic biological treatment: temperature, pH, load, carbon to nitrogen ratio, and toxic substances. Coagulation factors: 1, coagulant. 2, hydraulic conditions. 3, water quality conditions (pH, water temperature, suspended solids) Water treatment: raw water, coagulation, sedimentation, filtration, disinfection, drinking water (ozone oxidation, adsorption of activated carbon); Water: water pollution due to the involvement of a substance, and the chemical, physical, biological or radioactive properties change, thus affecting the effective use of water, harmful to human health or the destruction of the ecological environment, the ecological pollution phenomenon. Atmospheric stability: a measure of the ability of the atmosphere to diffuse pollutants into the atmosphere. The more unstable the atmosphere, the faster the rate of diffusion of pollutants in the atmosphere! Turbidity: the degree to which an insoluble substance in water affects the passage of light. The activated sludge in the wastewater with organic pollutants: medium in aeration conditions, all kinds of microorganisms were mixed in a continuous culture of bacteria fungi protozoa metazoan organisms such as sludge and metal hydroxides like brown floc formed by oxidation flocculation and adsorption performance of organic pollutants in water. Activated sludge process: with activated sludge suspended in water as the main topic, it is a method of sewage purification to fully contact with sewage in the environment which is favorable to the growth of microorganisms. The principle of activated sludge: life constantly injected air in the sewage water to maintain sufficient dissolved oxygen, after a period of time, which is generated in a sewage flocculation, the flocculation body is composed of a large number of breeding
