探讨了现有焦炉煤气输配系统在天然气转换中的改造与利用,及气源厂焦炉煤气的平衡问题。
3) water transmission and distribution system
输配水系统
1.
In the study of residual chlorine decay kinetics in water transmission and distribution system and its affecting factors,it was found that use of traditional first order reaction to simulate chlorine decay is not so accurate,multi-point chlorination and adjustment of dosing ratio will reduce the chlorine consumption,and pre-ozonation alone will increase the chlorine demand of filtered water.
研究了输配水系统中水体余氯的衰减动力学及其影响因素,发现用传统的一级反应模型模拟氯的衰减规律不够准确,因不同时段的衰减系数是变化的;采用多点加氯并调整投加比例可以降低耗氯量,单纯的预臭氧化会提高滤后水的需氯量。
