简介:摘要:This article mainly discusses the microbial control methods in the tap water treatment process. With the continuous improvement of people's requirements for drinking water quality, ensuring the microbial safety of tap water is extremely important. In the tap water treatment process, microorganisms in the water source may have a serious impact on water quality. To effectively control microorganisms, a combination of multiple methods is usually adopted. First, sedimentation is an important step. Through natural sedimentation or adding flocculants and other methods, suspended particles and some microorganisms in the water are precipitated.
简介:材料为0Cr18Ni9的不锈钢管路在环境适应性试验中焊缝处出现腐蚀。本文研究并分析、验证了不同酸洗钝化工艺对发动机不锈钢空气启动管路耐蚀性的影响。结果表明,钝化前增加酸洗膏、钝化后增加中和工序并进行封闭处理,可减少焊缝处的缝隙腐蚀,提高不锈钢焊接件耐蚀性,从而解决发动机空气气动管路锈蚀问题。
