Abstract

The invention relates to a system for treating lead-bearing petrochemical wastewater. An oil-water separating pool is divided into a pool section A and a pool section B which are isolated from each other in the flowing direction of sewage. The pool section B is divided into a tank B1 and a tank B2 which are isolated from each other. The pool section A is provided with a first liquid outlet and a second liquid outlet which are communicated with the tank B1 and the tank B2 respectively. The first liquid outlet and the second liquid outlet are each provided with a hydrophilic and oleophobic filter device. By means of the system, lead ions in lead-bearing waste petroleum water can be completely removed, oil components and water components can be reliably separated, oil components can be caught for reuse, the cost and cycle of subsequent biochemical treatment are decreased, and wastewater is efficiently treated.

Description

[0001] The present invention is a divisional application of an invention patent with an application date of December 10, 2014, an application number of 201410758357.6, and an invention title of "An Efficient Treatment System for Petrochemical Wastewater". technical field [0002] The invention relates to the field of sewage treatment, in particular to a system for treating lead-containing petrochemical wastewater. Background technique [0003] The petrochemical industry will produce a large amount of oily sewage. At the same time, due to the particularity of the petrochemical industry, the sewage usually contains lead ions. At present, there are also many methods and systems reported in the literature for treating oily sewage, but most of them cannot treat lead ions and oily components at the same time. Lead sludge, which is more difficult to handle. Contents of the invention [0004] The purpose of the present invention is to provide a system for treating lead-containing...
