Nowadays, many industries generate various industrial waste and sludge in the production process, such as municipal, chemical, electroplating, pharmaceutical, steel, papermaking, printing and dyeing, textile and other industries. If these sludge cannot be treated and disposed of in a timely manner, it will not only cause serious pollution to the environment, but also indirectly endanger human health. In order to protect the environment, the country strictly controls the discharge of sludge generated by enterprises. Therefore, enterprises use sludge drying equipment to treat and dispose of sludge, achieving harmless, reduced, and stable treatment of sludge. The benefits of using sludge drying equipment to treat sludge: 1. The sludge treated by the sludge drying equipment can meet environmental protection disposal standards, greatly reducing the harm of sludge to the environment. At the same time, the dried sludge can be reused as a secondary resource. 2. The sludge drying equipment utilizes heat transfer to quickly evaporate the moisture in the sludge, thereby achieving sludge drying, reducing the moisture content of the sludge to about 10%, greatly reducing the volume of the sludge, and greatly reducing the cost of sludge post-treatment. 3. The dried sludge can be directly bagged for transportation, avoiding the problem of water seepage before drying. At the same time, the volume of sludge is reduced to more than half of the original, greatly reducing the transportation cost of sludge. 4. The dried sludge tends to be hygienic and stable. Due to the presence of a large amount of organic matter, various pathogenic bacteria, and other harmful substances in the original sludge, after high-temperature treatment, it can effectively kill pathogenic bacteria and parasitic eggs in the sludge, which is not only hygienic but also greatly convenient for the post-treatment of the sludge. 5. Dry sludge can be recycled and reused. For example, sludge can be buried, incinerated, made into fertilizer, and made into various building materials (cement, bricks, ceramic particles, modified materials, etc.), It can improve the economic and usage value of sludge, and create new economic benefits for enterprises.
