The sludge treatment of urban sewage treatment plants is a global problem, and improper disposal can easily cause environmental pollution. According to statistics, there are currently about 600 sewage treatment plants in China. Calculated based on sludge production accounting for 0.3-0.5% of the total water treatment amount, the total monthly sludge discharge from urban sewage treatment plants in China is 140000 tons/year; And increasing at a rate of 10-20%; By 2010, it is expected that the national sludge production will be at least 100 million tons/year; In addition, most landfills now refuse to accept landfills. Causing serious disturbance to people and damaging natural ecology; Therefore, the treatment and disposal of sludge has become a very urgent issue.
The organic fertilizer granulator for sludge pond sludge is designed and manufactured using a new wet continuous push rod granulation process. This machine can not only granulate various organic substances, especially coarse fiber materials that are difficult to granulate using conventional equipment, such as crop straw, wine residue, bacterial residue, pharmaceutical residue, animal manure, etc., after fermentation, they can be granulated, but also achieve good granulation effects for raw materials such as humic acid and urban sludge.
Characteristics and advantages of granulation machines for organic fertilizer production equipment in sludge ponds:
The sludge pond organic fertilizer granulator consists of a body part, a granulator rotor part, and a transmission part. The working principle is that materials enter the machine from one end of the feeding port, and are continuously pushed through the granulation rotor and mechanically moved with the machine casing to achieve the purpose of granulation. The finished particles are pushed out of the machine at the other end of the machine. The rotor is driven by the motor and reducer of the transmission device, and the transmission and body parts are mostly fixed on the same frame. This not only has a sturdy structure, smooth operation, but also is very convenient to install. It is a new era of environmentally friendly fertilizer production equipment.
