Town Gas Generation Station Wastewater Treatment
Town gas generated from coal is widely used for daily cooking, heating and industry production. The generation process produces a large amount of gas, ash and wastewater that must be treated properly in order to protect the environment and public health. This article will discuss the wastewater treatment process for a town gas generation station in detail.
The wastewater produced from the town gas generation station is generated from the water content of the raw coal and can contain high levels of pollutants, such as suspended solids, oil and grease, and toxic chemicals. The wastewater needs to be pretreated before it is passed to the main treatment system where physical, chemical and biological processes are applied. In the pretreatment stage, the wastewater is screened to remove large objects and the pH is adjusted. The pH adjustment is important in order to maintain the optimal level for the subsequent stages of treatment.
The wastewater then passes through the main treatment system, which consists of several processes. The first stage of the main treatment system is sedimentation, in which the water is passed through large tanks in order to allow the heavier particles of solids to settle to the bottom. The resulting sludge is collected and disposed of in an appropriate manner.
The next stage of the process is biological treatment, which is used to remove the organic material from the wastewater. This is usually done with the help of micro-organisms, which feed on the organic material and convert it into harmless end products. After biological treatment, the wastewater is filtered through fine-grained media in order to remove any remaining particles.
The final stage of the treatment process is disinfection, in which the wastewater is treated with either chlorine or ultraviolet light. This step is important in order to ensure that any remaining bacteria and viruses are killed, thus making the wastewater safe for disposal.
Once the wastewater has been treated, it can be discharged into surface water bodies, such as rivers, streams, and lakes. It is important to note that the discharged wastewater must meet the required standards in order to protect the local water environment.
Overall, wastewater treatment for a town gas generation station is an essential process in order to protect the environment and public health. The process includes a variety of stages that help to remove pollutants, such as suspended solids, oil and grease, and toxic chemicals. In addition, the wastewater must be treated with disinfectants in order to kill any remaining bacteria and viruses. Finally, it is important to ensure that the discharged wastewater meets the required standards in order to protect the local water environment.
