在于提供一种可循环降解颗粒化调理剂及其在污泥堆肥中的应用。以解决传统有机调理剂的用量大、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,延长污泥堆肥周期的问题,同时解决无机调理剂部分残留于堆肥,降低有机质含量,影响堆肥成品质量的问题。

The invention provides a recyclable degradable granulation conditioner and its application in sludge composting. In order to solve the problems of large amount of traditional organic conditioners, difficult recycling, increasing the cost of sludge composting, slow degradation of organic conditioners in the later stage of composting, prolonging the period of sludge composting, and at the same time to solve the problems of residual inorganic conditioners in composting, reducing the content of organic matter and affecting the quality of finished compost products.
所提供的可循环降解颗粒化调理剂是粒径为0.5~10cm的木质均匀体。
The recyclable degradable granulation conditioner is a homogeneous lignin with a particle size of 0.5-10 cm.
所述木质均匀体是干燥的木材经破碎机、成型机等机械设备加工而成的粒径为0.5~10cm的球体或正方体。该木质均匀体具有粒径和形状相同、质量轻、流动性好、易筛分、可循环利用,吸水性好、可调节水分,易于微生物附着、可循环接种,可降解性、残留不影响成品质量的特点。
The wood homogeneous body is a sphere or cube with a particle size of 0.5-10 cm, which is processed from dried wood by mechanical equipment such as crusher and moulding machine. The wood homogenate has the characteristics of the same particle size and shape, light weight, good fluidity, easy screening, recyclable utilization, good water absorption, adjustable moisture, easy microbial attachment, recyclable inoculation, degradability and residue without affecting the quality of finished products.
可降解颗粒
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℃以上至少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 recyclable degradable granular conditioner in sludge composting are as follows: (1) mixing sludge and conditioner according to mass ratio of 1:0.35 to 1.35, the mixture material is obtained with moisture content of 55-65%; (2) mixing material is put into fermentation facilities for thermophilic aerobic fermentation, with ventilation rate of 0.05-6 m3/(min.m3), and the temperature of mixture material is maintained at least 5 days above 55;(3) fermentation for 9-20 days. After discharging, the conditioner is screened out by drum. The screening rate is over 98%. That is to say, the application of conditioner in sludge composting is completed. The water content of sludge is 75-85% and the organic matter content is 40-85% in step (1).
本可循环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。
The recyclable degradable granular conditioner can be used in sludge composting alone. Compared with the traditional conditioner, it has good fluidity and is easy to screen. After high temperature fermentation, the conditioner can screen more than 98%. It can be directly or recycled after air drying to reduce the operation cost of sludge composting.
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至9~20天,且明显提高了堆体的升温速度,发酵一天结束时升温可达28℃,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,为微生物创造了比较适宜的生长繁殖条件。
Because the conditioner of the invention is made of natural organic materials, has good microbial adhesion and good inoculation effect in recycling use, the fermentation time is shortened from one month of traditional high temperature composting process to 9-20 days, and the heating rate of the compost body is obviously increased. At the end of the first day of fermentation, the heating rate can reach 28 degrees C, whereas the heating rate of traditional high temperature composting process is generally only 6-15 degrees C/day. 。 The conditioner in the present invention is an organic substance with good air permeability, which degrades slowly in composting, has stable spatial structure and improves the mass transfer efficiency of air in the compost body. At the same time, the conditioner in the present invention has good water absorption, reduces the moisture content of sludge, improves the overall air permeability of the material, and creates the most 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,是一种肥效极佳的有机缓释肥和土壤改良剂。
The conditioner material of the invention is wood, which can be degraded, and the organic matter content of the finished product can not be reduced even if there is residual during screening. The conditioner of the invention 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 with excellent fertilizer effect and soil improver.
