随着原油含水逐步增高,含油污水处理在油田生产中起到越来越重要的作用。污水过滤罐是含油污水处理工艺的关键环节,过滤水质的好坏直接影响到注水质量和排放的环保问题。目前,六厂地区有重力式、压力单项、压力双向、机洗核桃壳、泵洗核桃壳、纤维球等6种过滤罐。我大队每年都承担部分过滤罐的维修和改造任务,在这过程中发现过滤罐存在憋压、跑料及腐蚀等问题,解决这些问题对提高污水处理质量和减少维修改造投资起到重要作用。
With the gradual increase of crude oil water content, oily wastewater treatment plays an increasingly important role in oilfield production. Sewage tank is the oily wastewater treatment process, the key link in the quality of the filter water directly affects the water quality and emissions of environmental issues. At present, there are six kinds of cans in the six factories, such as gravity type, single pressure, two-way pressure, machine-wash walnut shell, pump walnut shell and fiber ball. Every year, our unit undertakes the task of repairing and rebuilding some of the filter cans. During this process, it is found that the filter cans have such problems as pressure retention, running and corrosion. Solving these problems plays an important role in improving the quality of sewage treatment and reducing investment in maintenance and renovation.
