How to deal with blue carbon wastewater? The source of blue carbon wastewater, coal used in raw coal, low-temperature carbonization process and the depth of processing of chemical products and other factors. There are two main sources of blue carbon wastewater: one is dedusting washing water, which is mainly the crushing of raw coal and the dedusting washing water in the process of transportation, the dedusting washing water when the coke is charged or out of coke, Points and processing of dust washing water. This type of wastewater mainly contains high concentrations of suspended solid coal chips, blue carbon particles, etc., usually after clarification can be reused. Second, a low-temperature metamorphic coal in the low-temperature carbonization process and gas purification, blue coke quenching process formed in an industrial wastewater, complex composition, mainly containing high concentrations of organic and inorganic compounds, is a highly toxic pollutants, generally very Difficult to deal with reuse. Some blue carbon enterprises also have domestic sewage, coal washing section of coal washing wastewater. In recent years, there are many studies on the treatment of coking wastewater, such as incineration, electrochemical oxidation, coagulation, adsorption and the use of flue gas to treat coking wastewater. However, due to the high cost or poor operability, manufacturers Hope and stop. At present, the factory is widely used in ordinary biochemical treatment process, but its effluent indicators are not fully achieved. Therefore, we use polyaluminum chloride to deal with, polyaluminum chloride treatment process is relatively simple and more convenient, the effect is more obvious.
