Abstract:

In order to solve the problem that concentration multiple of the circulating water didn't reach the water standard of SINOPEC, some measures are made, such as improving technology of the back washing water for the side-filter and the sand-filter, installing the system of regulating the circulating water level, prohibiting the circulating water from discharging without permission and so on. On the basis of ensuring the circulating water quality, concentration multiple is raised and better economic benefits are gained.

Key words: concentration multiple, back washing water, regulating the circulating water level

摘要：

针对循环水浓缩倍数低于中石化指标的情况，采取了旁滤器和砂滤池反洗水的技术改造、增设循环水集水池液位调节系统和严禁私自排放循环水等措施后，在保证循环水水质的基础上，提高了循环水的浓缩倍数，取得了较好的经济效益．
