The coal granular activated carbon has high strength, well-developed pores and large specific surface area, especially the micro-pore volume. Coal-based activated carbon has strong adsorption capacity for organic matter, free chlorine and harmful gases in air in various water, and is an excellent adsorbent for deep purification of urban drinking water, and applied to remove bacteria and toxic gases in the air. Characteristics of granular activated carbon from coal: 1. The main characteristics of granular activated carbon from coal are low equipment investment, low cost, fast adsorption and strong adaptability to short-term and sudden water pollution. 2. It has obvious effect on removing chroma. The removal of chroma is reported to be up to 70% . The low chroma indicates that the removal efficiency of organic matter is high, and the removal effect of iron and manganese is good. 3. It has obvious effect on removing smell. Four. Helps remove anionic detergents. 5. Help to remove algae. The addition of coal granular carbon blocks the light absorption of algae, and has an obvious coagulation-aid effect in the low turbidity water source, which is helpful to remove algae in the coagulation precipitation. 6. The reduction in chemical oxygen consumption and five-day biochemical oxygen demand, which are positively correlated with the degree of organic pollution in water bodies, indicates the degree of removal of toxic and harmful substances from water bodies. Seven. It has good effect on phenol removal. 8. The turbidity of effluent is greatly reduced and the quality of tap water is greatly improved. 9. The effect on mutagenicity of water can effectively remove organic pollutants. It is a simple way to improve drinking water quality by conventional process.
