Embodiment Construction

[0029] Such as figure 1 As shown, a method for advanced treatment and reuse of polymer-containing sewage comprises the following steps:

[0030] 1. A method for advanced treatment of poly-containing sewage and reuse of poly-polymers, comprising the following steps:

[0031] A. Polymerized sewage flows into the first-level electric floating device for air flotation and degreasing after passing through the oil floating in the large tank;

[0032] B. Water purifying agent is added to the outlet water of the first-stage electric floatation device, and then enters the second-stage electric floatation device and the third-stage electric floatation device to remove suspended solids after passing through the pipeline mixer;

[0033] C. The water from the secondary and tertiary electric floating devices flows into the two-stage filter through the automatic energy-saving water supply device a, and the two-stage filter is filtered to make the content of suspended solids and oil in the w...

Abstract

The invention relates to a method for recycling injection polymers by polymer-containing sewage advanced treatment. On the basis of the water quality characteristics of the polymer-containing sewage and the polymer-containing sewage high-efficiency advanced treatment technique, the polymer-containing sewage can be recycled for injection polymers without lowering the viscosity of the polymer solution, thereby solving the problem of low viscosity of sewage injection polymers.

Description

technical field [0001] The invention relates to a method for advanced treatment and reuse of polymer-containing sewage and belongs to the technical field of oilfield polymer-containing sewage treatment. Background technique [0002] Oilfield oily sewage is the waste water after oil and gas separation and dehydration of oilfield production liquid, that is, oily sewage. This oily sewage not only contains crude oil, but also dissolves various salts, suspended solids, harmful gases, organic matter and a large amount of suspended solids; chemicals are usually added in the oil and gas treatment process. Commonly used treatment methods include floating oil, coagulation sedimentation-air flotation, and filtration. Traditional methods are unsatisfactory for the treatment of polymer-containing wastewater. [0003] Polymer flooding is an effective method to enhance oil recovery, and it has been applied in domestic oil fields, which produce more than 100 million cubic meters of polyme...
