Fu Hang intelligent fermentation tank sludge fertilizer

Shandong Fu Hang new energy smart thermophilic aerobic sludge treatment equipment Environmental Protection Technology Co., Ltd. developed and is currently Qingyun Kytril sewage treatment plant installation, commissioning date after the device can handle all of Kytril sewage treatment plant sludge, completely solve the Qingyun sludge treatment and disposal problems. The technology by high temperature aerobic fermentation of organic matter in the sludge decomposition, composting, sludge fermented product can be used as organic fertilizer for soil improvement, landscaping, realize sludge resource utilization. Smart thermophilic aerobic sludge treatment equipment Shandong Fu Hang New Energy Technology Co., Ltd. in 2013 a newly developed an efficient sludge fermentation equipment. Main features: 1, the process energy consumption, low operating cost; full use of space, small footprint; 2, high degree of automation, PLC and PC combined remote control; 3, the process is closed, no two secondary pollution; 4, the use of biological deodorization process emission standard; 5, the internal use of 304 stainless steel, corrosion resistance, long life; 6, with auxiliary air heating device to ensure normal operation at low temperatures. The main technical Rationale intelligent thermophilic aerobic sludge treatment process is dewatered sludge and straw and other agricultural waste materials are mixed according to a certain percentage of reflux, so moisture content of 60-65% after entering the treatment system design requirements, by vortex pumping oxygen to the sludge, and turned mixed in the hydraulic system and the sludge layer by layer itself fall under gravity, once fermentation process lasts eight days, so that the material fully aerobic fermentation decomposition, the heat released during decomposition enables Sludge own temperature, the maximum can reach 80 ℃, the fermentation process continuous evaporation of water sludge, partially decomposed organic matter, maturity, so that the sludge volume decreases, to reach the sludge reduction, stabilization treatment purposes . Device Configuration oxygen concentration sensor, temperature sensor, automatically adjusts the signal calculated by PLC to send oxygen and temperature, ventilation, oxygenation and stirring role in controlling sludge fermentation temperature between 55 ~ 65 ℃, reached sludge fermentation The optimum temperature, at this temperature, enabling the sludge pile in the death of a large number of pathogens and parasites, to achieve the purpose of safe disposal of sludge. As part of the treated material reflux material mixed with new feed material, most after packaging sold as organic fertilizer, resource utilization of sludge. Odor produced during fermentation through collection systems discharge into the deodorizing device, to avoid secondary pollution. Electric auxiliary heating system configuration to ensure that low-temperature environment to achieve rapid fermentation conditions to ensure continuous production at low temperatures. The basic operating conditions of the process (1) the organic content: content of ≥20%. (2) Moisture content: moisture content should be maintained between 50% to 65%. (3) the temperature should be maintained between 50 ~ 65 ℃, which remain above 55 ℃ time to more than five days. (4) nitrogen ratio (C / N) :( 20 ~ 30): 1. (5) pH value is controlled between 7 to 8.5. (6) ventilation rate: 3.0 ~ 3.6m3 / (m3 sludge · h). Fu Hang intelligent thermophilic aerobic fermentation equipment, and can be widely used in organic waste in municipal sewage sludge, manure, kitchen waste and so on. The device is put into the market, marking the blessing aircraft company to achieve new breakthroughs in organic waste treatment industry.
