两种污泥堆肥通风控制方式对比研究
Comparative study on two ventilation control modes of sludge composting
摘要
Abstract
If the composting product of dewatered sludge mixed with green waste under thermophilic and aerobic condition was used in city green and forestry, free treatment and resources recovery would be achieved. Ventilation is the most important control parameter of composting operation. In order to control the composting process more reasonably and enhance the quality of composting product, ventilation control mode is studied. Dewatered sludge is mixed with green waste for the thermophilic aerobic composting to investigate the effects on the composting process by ventilation control mode of time control or the time-temperature control. Results show that the temperature is up to 55℃ and maintains more than 3 days in the composting. The concentration of NH/-N is down to 0. 43mg/g. The loss rates of TN are 49.53% and 42.67% , and the degradation rates of TOC are 43.32% and 31.55%. Seed germination index is up to 80%. The best maturity time of composting under the time-temperature control is 12 days, and 14 days under the time control. Therefore, compared with the time control mode, there is better temperature control, organic content of meeting the standard requirements, lower nitrogen loss and shorter maturity time under the time-temperature control. The time-temperature joint control mode is superior to the time control mode.关键词
