高温可能会对城市固体废物(MSW)的生物降解产生不利影响，并导致用于收集垃圾填埋场渗滤液和垃圾填埋气的高密度聚乙烯(HDPE)管道的变形增加。本试验采用直井注水的方法改变直井周围的废弃温度。这项试验是在垃圾填埋场的新填埋层中以两种不同的流速间歇进行的。在本研究期间，同时监测了试验区的温度、气体压力和渗滤液水位。结果表明，注水有效地改变了垂直注水井周围的废温，渗滤液浓度并没有明显升高。注水过程中，从渗滤液液面到注水井底，水平方向上的温度影响距离随着深度的增加而增大。注水井井底温度降至注水温度附近。间歇注水对废气温度的影响范围在本次试验中略有增加。注水停止后，垂直注水井附近的废气温度开始快速上升，然后随时间的增加逐渐变得平缓。渗滤液水位稳定恢复后，注入井周围仍存在影响范围内的温度梯度。注水对渗滤液水位以上和远离注水井的垃圾的温度和气体压力影响不大。
High temperature may adversely affect municipal solid waste (MSW) biodegradation and lead to an increase in the deformation of high-density polyethylene (HDPE) pipes used for the collection of leachate and landfill gas in landfills. The test in this study was to change the waste temperature around the vertical injection well by water injection using a vertical well. The test was conducted intermittently with two different flowrates in a newly filled MSW layer of a landfill. The temperature, gas pressure and leachate level in the test area were simultaneously monitored during this study. The results showed that the waste temperature around the vertical injection well was effectively changed by water injection, which did not result in a significant rise in the leachate level. During water injection, the waste temperature influence distance in the horizontal direction increased with depth from the leachate level to the bottom of the injection well. The bottom temperature of the injection well decreased to near the water-injection temperature. The range of influence of the waste temperature caused by intermittent water injections slightly increased in this test. After water injection was stopped, the waste temperature near the vertical injection well increased quickly initially, and then the increments became more gradual with time. When the leachate level recovered stably, there was still a temperature gradient around the injection well within the range of influence. The temperature and gas pressure in the waste above the leachate level and far away from the injection well were slightly influenced by water injection.
