Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0033] As shown in the figure, the present invention is a modular treatment equipment for oilfield wastewater, including a dosing system 1, which retains a pH regulator, pre-oxidant, flocculant, and coagulant dispensing box. When required by normal operation, the pretreatment agent is added to the pretreatment reaction tank 2 through the dosing system to complete the pretreatment of the wastewater; the pretreated wastewater enters the micro-interface control reactor 3 by itself, and is fed by the dosing system 1 The flocculant is mixed and reacted in the micro-interface control reactor 3 to complete micro-interface coagulation, decolorization, and oil removal; the treated water enters the inclined tube sedimentation tank 4 by itself, and the length of the inclined tube in the inclined tube sedimentation tank 4 is 1000 mm, and the installation a...

Abstract

The invention relates to equipment for modular treatment of oil field wastewater. The equipment comprises a wastewater pretreatment unit, a micro interface control unit for performing coagulation, decoloration and oil removing on a micro interface, a sedimentation unit for removing relatively large particle impurities, a sand filter processing unit for retaining fine flocs, an ozone catalytic oxidation unit for removing poisonous and harmful substances, an adsorption processing unit for removing dissolvable organic matters and micro heavy metal ions, a membrane processing unit for further removing the impurities with large particle size and a sludge processing unit for disposing sludge. The specific equipment comprises a chemical feeding system, a micro interface coagulation reaction box, an inclined tube sedimentation box, an intermediate booster pump, a filter, an ozone catalytic oxidation reactor, an activated carbon adsorption device, a membrane processing device, a stacked type sludge water extractor and a matching pipeline and valve control system. By the equipment, corresponding processing unit can be started through the preset pipeline control system according to different destinations of treated wastewater, and modular treatment of different kinds of oil well operation wastewater is realized.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment and relates to the treatment of oilfield wastewater, in particular to modularized treatment equipment and technology for oilfield well site wastewater. Background technique [0002] Oil field well site wastewater is the oily wastewater produced during oil well stimulation operations, including well washing, well workover, well completion and cementing, fracturing and other measures, and its common water quality characteristics are high COD, high turbidity, Higher content of emulsified oil. Due to the high COD of wastewater and the lack of nutrients needed for microbial growth, it is not suitable for biological treatment; chemical oxidation is used to treat well site wastewater, the dosage of oxidants is large, the treatment efficiency is not high, the treatment takes a long time and costs huge. Contents of the invention [0003] In order to overcome the above-mentioned deficiencie...
