Problems solved by technology

The above-mentioned methods all have their own disadvantages. Some of them have large investment in treatment equipment and high operating costs of chemicals;
In the CN 1240623C patent announced on February 8, 2006, a sewage treatment method integrating flocculation, adsorption, oxidative degradation, and filtration is disclosed, but this method is mainly used to treat urban domestic sewage, dyeing and finishing sewage, and paper products. Processing sewage, hardware processing sewage, shoemaking sewage and other eutrophic sewage and other sewage, the treatment effect on mine sewage is not good
At present, there is no low-cost and fast way to treat drilling sewage

Embodiment Construction

[0009] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0010] In addition to clay, oil and inorganic salts, the sewage in the drilling process also contains various organic treatment agents that are difficult to degrade, such as sulfonated phenolic resin (SMP), sulfonated lignite (SMC), sulfonated tannin extract (SMK), Iodized tannin (SMT), condensed ring organic compounds and polymerized humic acid, etc. The appearance of the sewage is dark brown, the composition is complex, and it has the characteristics of high chroma, high turbidity, high COD and high stability.

Abstract

The invention discloses a disposing method of drilling well, which comprises the following steps: flocculating; micro-electrolyzing; oxidizing to remove iron; adsorbing; filtering; hyperfiltrating. The invention reduces investment and cost for operating price, which is significant to protect water resource, environmental protection and business harness.

Description

technical field [0001] The invention relates to a treatment method for sewage, in particular to a treatment method for drilling sewage. Background technique [0002] Drilling wastewater produced during the exploration and development of oil and gas has a large amount, complex composition, deep color, and high content of soluble organic matter. It is a special type of high-concentration organic wastewater that cannot be discharged or used directly. It must be treated before it can be discharged or reused. .
