Shuitu Baochi Xuebao, 2023 为明确不同砂土混合物覆盖对土壤蒸发过程的影响,基于土壤蒸发分阶段理论及微型蒸渗仪田间试验,深入探析了6种砂土混合覆盖模式(1.0,0.8,0.6,0.4,0.2,0,分别为M1~M6)下的土壤蒸发动态变化及其作用机制。结果表明:土壤蒸发分阶段理论能够真实刻画砂土混合覆盖下的土壤水分蒸发状况,其累计蒸发量可用砂土混合比与蒸发时间进行定量表征。当砂土混合比≥0.8时,土壤蒸发过程仅存在2个明显阶段,抑蒸效果显著;当砂土混合比＜0.5时,M3~M6处理的土壤蒸发稳定高峰期明显,且集中于前2.53~2.66天 ...

Shuitu Baochi Xuebao, 2020 土壤蒸发是地表水分平衡及能量交换的组成部分，是干旱和半干旱区水文循环的关键环节。为探究黄土高原水蚀风蚀交错区生物结皮对土壤蒸发的影响，以风沙土和黄绵土上发育的藓结皮为研究对象，通过模拟蒸发试验和自然蒸发试验，测定了不同蒸发条件下藓结皮覆盖土壤和无结皮土壤的蒸发强度，分析了藓结皮覆盖土壤的蒸发特征及其与无结皮土壤的差异。结果表明：（1）模拟蒸发试验中，藓结皮对土壤蒸发过程的影响表现出明显的阶段性，与无结皮土壤相比，藓结皮使土壤蒸发强度在大气蒸发力控制阶段降低了3.04%~15.46%（0.21~1.05 ...

Shuitu Baochi Xuebao, 2020 为研究蒸发阶段不同覆膜开孔条件下土壤水分运动，在室内进行蒸发模拟试验的基础上，采用HYDRUS-1D模型对不同覆膜开孔率和大气蒸发能力条件下土壤剖面含水率和潜水蒸发量动态变化进行了模拟，并与实测资料进行比较。结果表明：土壤剖面含水率同时受大气蒸发能力和覆膜开孔率的共同作用，随覆膜开孔率和大气蒸发能力的增加，土壤剖面含水率减小，且上层土壤含水率差异比下层土壤明显；覆膜开孔率和大气蒸发能力-定时，土壤剖面含水率在蒸发初期有所增加，蒸发后期基本保持稳定；覆膜对潜水蒸发的阻滞作用明显，但开孔率增加到-定数值时 ...

Gongye shui chuli, 2021 采用接触式蒸发处理垃圾渗滤液纳滤膜浓缩液，考察了气体温度、气体流量、初始pH和蒸发率对冷凝液水质的影响。结果表明：随着气体温度的增加，稳定蒸发温度不断提高，冷凝液COD先降低后升高，而NH3-N先升高后降低；随着气体流量的增加，冷凝液COD先降低后升高，而NH3-N不断增加；随着初始pH的升高，冷凝液COD降低，而NH3-N则相反。蒸发初期，冷凝液COD及NH3-N较高，随蒸发率的提高，其含量不断降低，并在末期有所提高；蒸发初期和末期气体夹带较为显著。

Gongye shui chuli, 2021 介绍了某热电厂脱硫废水旁路烟道蒸发系统工程设计开发及其应用情况。通过热力模拟计算分析发现，利用烟气蒸发不能消耗现有全部脱硫废水，需要对脱硫废水进行减量处理。本工程设计采用软化浓缩工艺对脱硫废水进行减量处理，所得淡水回用，而浓盐水去旁路烟道蒸发系统。运行结果表明：反渗透浓水中钙离子浓度控制在4 mmol/L以内，能满足反渗透装置长时间运行；蒸发塔抽取的最大热烟气量可以达到5%~6.5%，蒸发塔运行压差均小于空预器压差；喷枪的耐磨性要好于雾化盘。
