摘　　要：本文采用三种不同的覆膜抽气模式对填埋场作业面进行除臭试验研究,结果表明:覆膜1.0mm+3台负压车、2条负压管比单层覆膜0.3mm+1台负压抽气车、2条临负压管或覆膜0.3mm+3台负压车对氨气、硫化氢和臭气浓度的去除效果都要更好;但覆膜抽气法对总挥发性有机物(Total Volatile Organic Compounds,TVOC)的去除效果较之前更差,这主要是由于TVOC主要为分子量较大的有机物,扩散较慢,且垃圾堆体在厌氧条件下产生的TVOC浓度更高。Three different film extraction modes are used to conduct deodorization experiments on the landfill working surface.The results show that 1.0mm + 3 negative pressure vehicles with two negative pressure tubes,0.3mm + 1 negative pressure suction truck with 2 layers of negative pressure,2 negative pressure tubes or 0.3mm + 3 negative pressure films Pressing the car has a better effect on the concentration of ammonia,hydrogen sulfide and odor.However,the removal effect of Total Volatile Organic Compounds (TVOC) by the film-covered pumping method is worse than before.This is mainly because TVOCs are mainly organic compounds with large molecular weights,which diffuse slowly,and the waste piles are tired Higher TVOC concentrations are produced under oxygen conditions.
