Example Embodiment
[0050] Example 1:
[0051] Take 10kg of sludge (moisture content of 80%) and 5kg of sawdust from a domestic sewage treatment plant, mix and stir, spread it to a cool drying field, and dry it under direct sunlight to a moisture content of 30% to obtain a mixture of 10kg. Then the mixture is beaten Large condensate is broken to less than 20mm in diameter. Heat the experimental muffle furnace (muffle furnace is a closed high-temperature furnace for experiments, which can replace the carbonization furnace in the test) to 750°C, put the mixture into the tray, put it in the muffle furnace, and heat for 15 minutes. Take it out after cooling down to get about 4kg of sewage peat fertilizer.
[0052] According to the experiment, the final black granular solids are:
[0053] The diameter is 2~8mm;
[0054] Specific surface area is 195m 3 / g;
[0055] Nitrogen content: 2.21%;
[0056] Phosphorus content: 8.24%;
[0057] Potassium content: 1.97%.
Example Embodiment
[0058] Example 2:
[0059] Take 10 tons of sludge from a domestic sewage treatment plant (moisture content of 80%), crush bamboo, tree branches, etc. to wood chips (bamboo chips) with a diameter of 1-15 mm, and take 3 tons of charcoal powder from the charcoal plant 2 Tons (1~15mm in diameter), fully mixed, total weight 15 tons; transport the materials to the KJG paddle dryer, and use the heat transfer oil indirect heating method (the heat transfer oil temperature is 160℃) to heat the materials Dry, and fully mix and granulate the materials through the rolling and stirring of the blades inside the dryer. After 25 minutes, the materials are dried to 30% moisture content and enter the BMS sludge carbonization furnace through the closed spiral conveying pipe; the temperature of the carbonization furnace Preheat to 760°C, start to receive materials, after 18 minutes of carbonization, it becomes black carbonized. After being cooled to 200°C by a tubular water cooling device, the carbo...
