人工湿地废弃植物制备成型燃料
|
摘要
[目的]提高人工湿地植物资源化利用水平。[方法]以收割的废弃植物为原料,通过冷压成型制备成型燃料,研究了成型压力、粘结剂添加量、原料含水率对成型燃料密度和机械强度的影响。[结果]成型燃料制备的最优工艺参数为成型压力40 MPa、粘结剂添加量15%、原料含水率8%,在此条件下制得的成型燃料密度和抗跌强度分别高达0.97 g/cm和96%。[结论]该研究为人工湿地植物处理处置问题提供了新的思路。
[Objective] The study aimed to improve the resource utilization level of constructed wetland plants. [Method] Plant residues from constructed wetlands were used to prepare briquette fuel by cold briquetting,and effects of pressure,binder dosage and moisture content on density and shatter strength of briquette fuel were investigated.[Result]The optimum parameters for the preparation of briquette fuel were shown as follows: pressure was 40 MPa; binder dosage was 15%; moisture content was 8%. Density and shatter strength of briquette fuel prepared under the optimum conditions were respectively 0. 97 g / cm3 and 96%.[Conclusion] The research could provide a new idea for the treatment and disposal of plants in constructed wetlands.
