Mobile skid-mounted equipment for efficient water treatment

Abstract

The invention relates to mobile skid-mounted equipment for efficient water treatment. The mobile skid-mounted equipment for efficient water treatment can operate continuously or intermittently and is characterized by comprising three independent skid-mounted parts, namely, a pre-treatment flocculent precipitation system, a biological treatment system and a deep membrane treatment system, and the integrated mobile skid-mounted treatment equipment is communicated with a sewage tank through a conveying water pump; in terms of flocculent precipitation, a specific agent is adopted, and suspended matter as well as poisonous and harmful heavy metal and the like can be removed through accurate flocculation, stirring and precipitation; the biological treatment system comprises an aerobic tank, an MBR (membrane biological reactor) tank and the like; the deep treatment device can remove high salt and other ions through filtration of reverse osmosis membranes. The equipment has the benefits as follows: discharged water meets the national discharge or reuse standard after collected waste water in oil and gas fields is treated through the integrated skid-mounted equipment for water treatment. The equipment has the advantages of advanced technique, stable performance, good treatment effect, little investment, simplicity in operation, convenience in management, use and maintenance and the like and is a whole set of mobile treatment device specially designed according to water quality characteristics of the waste water in the oil and gas fields.

Description

technical field [0001] The invention relates to a waste water treatment system for oil and gas fields, belonging to the fields of waste water purification, recycling and the like. Background technique [0002] Oil well fracturing stimulation technology in oil and gas fields is the main technology used in the world for traditional oil well stimulation and shale gas development stimulation. During the fracturing process, thousands to tens of thousands of cubic meters of fracturing fluid will be pressed downhole in a short period of time. To crack the downhole oil-rich rock formation to open more oil outlet channels, the fracturing fluid is usually equipped with glue-like polymer materials, fracturing sand, functional additives, and water, and the next step after the fracturing operation Within a few days, the fracturing fluid will carry the drilling residual mud fluid, acid liquid, crude oil, natural gas, downhole rock debris, downhole sediment, rubber polymer, fracturing sand...
