Abstract

Abstract The objective of this work was to evaluate the use of bentonite as an additive in the composting of wastewater sludge from the poultry agroindustry regarding nitrogen conservation, carbon degradation, and nutrient content increase. The experimental design was completely randomized with five treatments with bentonite at 0, 0.5, 1.0, 3.0, and 6.0%, with three replicates. The organic compost used in the treatments consisted of pine sawdust and wastewater sludge from the treatment plant. During and after the composting process, the following were analyzed, respectively: pH, dry matter, temperature, and C, N, NH4+, NO2-, and NO3- contents; and P, K, Ca, Mg, Cu, and Zn contents and humic and fulvic acid concentrations. Bentonite at 6.0% increased C degradation, N losses, Mg content, and humification, but decreased Zn content and humidity. Bentonite, as an additive in the composting of sludge from the poultry agroindustry, promotes humification, decreases Zn content and humidity, but does not affect pH and P, K, Cu, NH4+, NO2-, and NO3- contents.

膨润土在禽畜农业废水污泥堆肥中的应用
摘要本研究的目的是评价膨润土作为添加剂在禽畜农业废水污泥堆肥中对氮保护、碳降解和营养成分增加的影响。试验设计采用完全随机化设计,分别添加0、0.5、1.0、3.0和6.0%膨润土5个处理,3个重复。处理中使用的有机堆肥由松木屑和处理厂的废水污泥组成。在堆肥过程中和堆肥后,分别对pH、干物质、温度和C、N、NH4+、NO2-、NO3-含量进行分析;P、K、Ca、Mg、Cu和Zn含量以及腐殖酸和黄腐酸浓度。膨润土浓度为6.0%时,C降解、N损失、Mg含量和腐殖化增加,Zn含量和湿度降低。膨润土作为家禽农业污泥堆肥添加剂,促进腐殖化,降低Zn含量和湿度,但不影响pH和P、K、Cu、NH4+、NO2-和NO3-含量。
