Bleeding is usually the last step of the storage tank and a very important link in the whole chemical process. In the process of chemical production, waste liquid and waste gas are inevitable products, which will cause serious harm to the environment and human health if they are not treated and discharged in time. Therefore, cleaning is an essential step in the chemical process.
In the cleaning operation, appropriate treatment methods must be selected according to the nature and pollution degree of waste liquid or waste gas. Common treatment methods include physical treatment, chemical treatment and biological treatment. For example, for waste liquid containing organic matter, biological treatment can be used to decompose organic matter into harmless substances through the action of microorganisms; For the waste liquid containing heavy metals, chemical treatment is needed, and heavy metals are precipitated by adding chemical agents to achieve the purpose of purification.
In short, cleaning is a very important step in the chemical process, which can effectively reduce the harm of chemical substances to the environment and human health, and protect the ecological environment and human health.
