风城特稠油污水属于重碳酸钠水型,水质矿化度高,在传统双滤料过滤器和锆英砂过滤器筛管表面易结垢导致筛管堵塞及滤料板结,造成过滤器处理能力短期内下降,既影响了生产又增加了清洗成本。本文主要针对特稠油污水处理过程中存在的筛管结构问题,研发改性聚四氟乙烯荷电膜滤芯,对特稠油联合处理站水区一级过滤出口和进口做了污水膜法处理以及膜组件耐高温试验,为过滤器的优选供技术支持。
Fengcheng special heavy oil wastewater belongs to the sodium bicarbonate water type, high water quality salinity, in the traditional dual filter and zircon sand filter screen surface scaling causes screen blocking and filter board knot, causing the filter Short-term processing capacity decline, both affecting the production and increase the cleaning costs. In this paper, we mainly deal with the problem of sieve pipe structure in the process of extra heavy oil wastewater treatment. We developed a modified PTFE membrane filter, As well as the membrane module high temperature test, the filter for the preferred technical support.
