成都地区回收污水中热能的潜力分析

摘要

In order to study the capacity of sewage cooling and heating source in Chengdu, this paper measures the full-year temperature of sewage of a hotel in Chengdu, statistics the number of sewage treatment plant and sewage discharge in recent years, calculates and analyze the capacity of recovery and utilization of sewage from the perspective of energy saving, economic and environmental protection. The analysis results show that the temperature annul change of sewage in Chengdu is small, sewage discharge is huge and stable, the capacity of sewage cooling and heating source is great, and sewage source heat pump is more energy, more economical and more green.%为研究成都地区污水中冷热资源赋存量的大小，测量成都某酒店污水干渠全年污水的排放温度，统计近年成都市污水厂数量和污水排放总量，从节能、经济和环保角度对成都地区污水热能回收利用的潜力进行计算和分析。结果表明，成都地区污水温度冬暖夏凉，全年变化幅度小；污水排放量大且稳定；成都地区污水中冷热资源赋存量大；与传统供暖制冷系统相比污水源热泵系统更节能、经济、环保。
