Abstract

The invention discloses a treatment system of a shale gas fracturing flowback fluid. The treatment system is characterized by comprising a reaction tank, a tubular microfiltration membrane system, a nanofiltration system and a reverse osmosis system, wherein a chemical agent is added to the reaction tank; chemical precipitation treatment is performed on waste water entering the reaction tank; a treated supernate is conveyed to the tubular nanofiltration system; treated fresh water is conveyed to the reverse osmosis system for treatment. The treatment system of the shale gas fracturing flowback fluid is compact in structure, small in floor area, short in treatment process, high in treatment efficiency, good in outlet water quality, low in power consumption, low in operating cost, convenient in automatic control, and high in economic benefit.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a shale gas fracturing flowback liquid treatment system. Background technique [0002] As an important unconventional natural gas resource, shale gas has become a new highlight in the exploration and development of global oil and gas resources, but its special drilling and production technology may bring new environmental pollution problems, especially in the process of shale gas fracturing A large amount of fracturing flowback wastewater will be produced, which contains formation groundwater, waste fracturing fluid and drilling cuttings brought out along with the flowback wastewater, and has high salt, high salinity, high chroma, and toxic Hazardous substances, poor biodegradability and intractable characteristics. The current concentration process for treating shale gas fracturing flowback fluid wastewater is softening + ultrafiltration + reverse osmosis concentration...
