my country's sludge is mainly divided into two parts: industrial sludge and urban sludge. According to relevant statistics, my country’s urban sludge production is expected to exceed 40 million tons in 2020, and industrial sludge production will be close to 40 million tons, a total of about 80 million tons. China's sludge production is increasing day by day. The harmless treatment and resource utilization of sludge are the future development direction. Traditional sludge disposal methods such as landfill and incineration will become less and less used. Purchase low-temperature sludge drying equipment Dezhou Guangyuan Environmental Protection.

Such a huge market size is a challenge and development opportunity for China's sludge treatment industry. The current situation of the sludge treatment industry in my country is that the sludge treatment method is immature and the sludge treatment technology is relatively backward, which cannot meet the needs of sludge treatment. At present, the main methods of sludge disposal in my country are land utilization, landfilling, building materials utilization and incineration, but the disadvantages of these sludge disposal methods are obvious. For example, landfill and incineration are likely to cause "secondary pollution" to the environment. Faced with the severe forms of sludge treatment in my country, only by adopting technical means to find more economical and reasonable sludge treatment schemes can the current sludge treatment problems be effectively solved. Sludge treatment technology is an effective way to solve this problem. Sludge treatment includes thickening (99% water content), dewatering (80%), drying (10%) and so on. In the dewatering step, sludge mechanical dewatering equipment can be used for sludge dewatering. The new sludge treatment equipment, namely dehumidification heat pump sludge drying equipment and low-temperature waste heat sludge drying equipment, are generally used for sludge drying in the sludge drying process, and the sludge can be dried as low as 10%.
