As a professional who has been engaged in the maintenance of chemical equipment for a long time, I would like to share some information about the tank bottom Sludge treatment Practical experience and knowledge. Tank bottom sludge is a common industrial waste. Improper treatment will cause serious environmental pollution. Therefore, correct and effective treatment methods are essential.
1、 Formation and harm of sludge
Tank bottom sludge is mainly produced during the loading, unloading, storage and transportation of storage tanks in petroleum, chemical, grease and other industries. These sludge contain a large number of harmful substances such as oil, grease, heavy metals and organic matter, which have caused great harm to human health and the environment. If not treated in time, the oil sludge will gradually decompose and harden, forming hard lumps that are more difficult to treat, and at the same time, harmful gases and liquids will be released, polluting the soil and groundwater.
2、 Common methods of sludge treatment
1. Mechanical treatment method: use the suction, scraping, excavation and other mechanical functions of excavation machinery, cooperate with manual treatment, and sort out the oil sludge. This method is simple and easy to operate, but the treatment effect is unstable, and it is easy to cause secondary pollution to the environment.
2. Chemical treatment method: use chemical reaction to decompose oil sludge, which has obvious effect and no pollution to the environment. At present, there are chemicals specially developed for oil sludge cleaning on the market, and the use effect is very good. In addition, incineration, thermal decomposition, biodegradation and other treatment methods can also be used.
3、 Sludge treatment method based on professional knowledge and experience
When dealing with the sludge at the bottom of the tank, we usually adopt a comprehensive treatment method, that is, first use the mechanical method to sort out the large sludge, and then use the chemical method to decompose the remaining sludge. The specific steps are as follows:
1. Cleaning: First, we need to clean the oil sludge at the tank bottom. Use excavation machinery to sort out large pieces of oil sludge and ensure that the environment is clean during operation.
2. Preliminary treatment: Conduct preliminary treatment on the cleared sludge, and use the crusher and milling cutter to crush and cut the sludge for further treatment. In this process, attention should be paid not to let the harmful substances in the oil sludge pollute the surrounding soil and groundwater.
3. Chemical treatment: use special sludge decomposition chemicals, add them to the sludge, and use chemical reaction to decompose harmful substances in the sludge into harmless substances. This process needs to strictly control the dosage of chemicals and reaction time to ensure the treatment effect.
