摘要
为了解贵阳市污水热能的适用性,预测贵阳市污水对污水热能应用的热交换设备产生腐蚀和结垢情况,可为污水热能的利用提供理论数据支持。通过对贵阳市城市污水水质的监测,分析出贵阳市小河污水处理厂在温度变化较大的月份的污水指标值。应用朗格利尔饱和指数(LSI)法、赖兹纳稳定指数(RSI)法、帕科拉兹结垢指数(PSI)法3种指数分析方法,判断出贵阳市的污水腐蚀、结垢趋势。结果表明,贵阳市污水的可利用性较强,可以满足污水源热泵系统对水质的要求。
To forecast the situation of corrosion and scaling generated the heat exchange equipment, promote the use of sewage heat, the sewage indexes of the Xiaohe sewage treatment plant on the month when temperature changed greatly were investigated.By the application of 3 kinds of index analysis including LSI, RSI, PSI, the corrosion and scaling tendency of the sewage were determined.The results showed that using the sewage heat in Guiyang was available.
