一种可循环降解颗粒化调理剂解决了传统有机调理剂用量大、难以循环利用，增加污泥堆肥成本，和有机调理剂堆肥后期缓慢降解，延长堆肥周期的问题，同时解决了无机调理剂残留于堆肥，降低成品质量的问题。

A kind of recyclable degradable granulated conditioner solves the problems of large amount of traditional organic conditioner, difficult recycling, increasing the cost of sludge composting, slow degradation of organic conditioner in the later stage of composting, and prolonging the composting cycle. At the same time, it solves the problem of inorganic conditioner remaining in the compost and reducing the quality of finished products.

本发明可循环降解颗粒化调理剂是粒径为0.5～10cm的木质均匀体。应用：(1)将污泥与调理剂混合，得混合物料;(2)混合物料高温发酵;(3)发酵后出料，然后筛分出调理剂，筛分率98%以上。本发明调理剂空间结构稳定、流动性好、易筛分、能循环使用，吸水性好、可调节水分，微生物附着性好、可循环接种，残留不影响成品质量。本发明具有很高的推广应用价值。

The recyclable degradable granulated conditioner is a wood homogenate with a particle size of 0.5 ~ 10cm. Application: (1) mixing sludge and conditioner to obtain mixed materials; (2) High temperature fermentation of mixed materials; (3) After fermentation, the material is discharged, and then the conditioner is screened out, with a screening rate of more than 98%. The conditioner has stable spatial structure, good fluidity, easy screening, can be recycled, has good water absorption, can adjust water content, has good microbial adhesion, can be recycled for inoculation, and the residue does not affect the quality of finished products. The invention has high popularization and application value.

可循环降解颗粒化调理剂在污泥堆肥中的应用步骤为：(1)按质量比1∶(0.35～1.35)将污泥与调理剂混合，得混合物料，混合物料含水率为55～65%;(2)混合物料放入发酵设施内高温好氧发酵，通风速率为0.05～6m3/(min·m3)，维持混合物料温度在55℃以上少5天;(3)发酵9～20天后出料，然后经滚筒筛筛分出调理剂，筛分率在98%以上，即完成调理剂在污泥堆肥中的应用。其中步骤(1)中污泥的含水率为75～85%，有机质含量为40～85%。

The application steps of recycled degradable granulated conditioner in sludge composting are as follows: (1) the sludge and conditioner are mixed according to the mass ratio of 1:0.35 ~ 1.35 to obtain a mixed material with a moisture content of 55 ~ 65%; (2) The mixed materials are put into the fermentation facilities for high-temperature aerobic fermentation, the ventilation rate is 0.05 ~ 6m3/ (min · m3), and the temperature of the mixed materials is maintained above 55 ℃ for at least 5 days; (3) After 9 ~ 20 days of fermentation, the material is discharged, and then the conditioner is screened out by roller screen. The screening rate is more than 98%, that is, the application of conditioner in sludge composting is completed. The water content of sludge in step (1) is 75-85%, and the organic matter content is 40-85%.、

可降解颗粒化调理剂可以单独应用于污泥堆肥中，相比传统调理剂，流动性好，易筛分，高温发酵出料后调理剂能筛分出98%以上，直接或经风干后循环使用，降低污泥堆肥的运行成本。由于本发明调理剂为天然有机材料制成，微生物附着性好，循环使用起到很好的接种作用，使发酵时间由传统高温堆肥工艺的一个月缩短9～20天，且明显提高了堆体的升温速度，发酵结束时升温可达28℃，。

Degradable granulated conditioner can be applied to sludge compost alone. Compared with traditional conditioner, it has good fluidity and is easy to screen. After high-temperature fermentation and discharge, the conditioner can screen more than 98%. It can be directly or recycled after air drying to reduce the operation cost of sludge compost. As the conditioner of the invention is made of natural organic materials, the microorganism has good adhesion, and the recycling plays a good role in inoculation, so that the fermentation time is shortened from one month of the traditional high-temperature composting process to 9 ~ 20 days, and the heating rate of the pile is significantly increased. The heating up can reach 28 ℃ at the end of the fermentation day,.

而传统高温堆肥工艺的升温速度一般仅为6～15℃/天。本发明中调理剂为透气性好的有机物，在堆肥中降解速度缓慢，空间结构稳定，提高了空气在堆体内的传质效率，同时本发明中调理剂有良好的吸水性，可降低污泥的含水率，提高物料整体的透气性能，为微生物创造了适宜的生长繁殖条件。

However, the heating rate of traditional high-temperature composting process is generally only 6 ~ 15 ℃ / day. The conditioner in the invention is an organic substance with good air permeability, which is degraded slowly in the compost, has a stable spatial structure, and improves the mass transfer efficiency of air in the reactor. At the same time, the conditioner in the invention has good water absorption, which can reduce the water content of sludge, improve the overall air permeability of materials, and create suitable growth and reproduction conditions for microorganisms.

本发明调理剂材质为木材，可降解，即使筛分时有残留，也不会降低成品有机质含量。本发明调理剂在污泥堆肥中应用，所得成品具有有机质含量高、氮磷钾养分含量高、肥效作用时间长等优点，是一种肥效好佳的有机缓释肥和土壤改良剂。

The conditioner of the invention is made of wood and can be degraded. Even if there is residue during screening, the organic matter content of the finished product will not be reduced. The conditioner is applied in sludge composting, and the finished product has the advantages of high organic matter content, high nitrogen, phosphorus and potassium nutrient content, long fertilizer effect time, etc., and is an organic slow-release fertilizer and soil conditioner with good fertilizer effect.
