The earliest use of thermal drying technology in the world for sludge treatment was Bradford, which originated in the United Kingdom. At the beginning of the 20th century, the company developed the rotary kiln-type sludge dryer for the first time and applied it to the sludge drying practice. At the end of the 1980s, the sludge drying technology was gradually emphasized by people, and the sludge drying technology was Application and promotion have promoted the change of sludge treatment and disposal methods. This change is mainly reflected in: before sludge is disposed and disposed, the sludge should be dried; the proportion of sludge incineration and disposal is greatly improved; dry sludge The product is sold as a fat source for land reuse, and the scale of the industry is continuously expanding. Today, the sludge drying process has also received increasing attention from the environmental engineering community in developing countries.
In China, with the enhancement of the country’s economic strength and the improvement of national environmental awareness, the urban sewage treatment industry has developed rapidly. The output of urban sludge has been increasing day by day. The disposal and development of sludge has attracted increasing attention. Sludge drying treatment makes it possible to use sludge for agriculture, use as fuel, incineration, and even reduction of landfill sites. The improvement and innovation of sludge drying technology directly promotes the development of sludge disposal methods, expands the range of sludge treatment options, and makes it more reliable in terms of safety, reliability, and sustainability. . With the start of the domestic sludge treatment market, a variety of sludge drying equipment came into being, but the sludge drying process requires the consumption of a large number of heat sources, increasing the cost of sludge disposal. What are the characteristics of various sludge dryers, the relationship between the treatment scale and the selection of sludge drying equipment, and how to obtain a set of drying systems with the best combination of technological maturity, investment and operating costs, our company will introduce you to one!Medical Cart & Cabinet series including all types of medical cart and cabinet, which are widely use at hospital or beauty salons.
