Description
Technical field:
The present invention relates to a kind of oil-contaminated water of oil field processing technology field, particularly the comprehensive biochemistry pool of a kind of dynamic multi-level A-O.
Background technology:
From stratum, exploit out the mixing liquid of oil and water in oil-field development production process, after processed, the oily(waste)water decontaminated water treatment station deviate from processes.The domestic and international method processed oily(waste)water has four kinds: one to be carry out conventional processing at present, process qualified after be transported to thin oil block and carry out waterflooding; Two is carry out advanced treatment, processes qualified Water circulation in injection boiler, develops for heavy oil block steam injection; Three is select the stratum of end-of-development to carry out invalid recharging, and temporarily stores; Four is carry out biochemical treatment and advanced treatment, processes qualified sewage standard discharge.In the middle and later periods of oil-field development, in the oil of extraction and the mixing liquid of water, the content of water increases year by year, cannot fully recovering water filling, steam injection exploitation, therefore producing a large amount of oily(waste)water needs process up to standard outer row afterwards.Along with the Persisting exploitation in oil field, externally discharged waste water amount will increase year by year.
For ensureing oily(waste)water standard discharge, need to carry out process up to standard to the organic pollutant contained in oily(waste)water.The biochemical processing process that conventional sewage process both at home and abroad adopts at present has three kinds: one to be adopt " A-O (acidication-catalytic oxidation) " technique to carry out biochemical treatment; Two is adopt " A-BAF (fixation of microbe-BAF) " technique to carry out biochemical treatment; Three is adopt " A-O
3(inner circulating aerating biological filtering tank) " technique carries out biochemical treatment.Due to oil-contaminated water of oil field there is Components of Organic Pollutants complexity, emulsification of crude oil is serious, suspension content is high, water quality, the water yield fluctuate large feature, in above-mentioned three kinds of biochemical processing process process oily(waste)waters, organic pollutant efficiency is low, cannot meet the requirement of oil-contaminated water of oil field process up to standard.
Summary of the invention:
The technical problem to be solved in the present invention is to provide the comprehensive biochemistry pool of a kind of dynamic multi-level A-O, the arrangement achieves and combination can adopt different biochemical processing process when different quality, water yield change, in process oily(waste)water, organic pollutant efficiency is high, meet the requirement of oil-contaminated water of oil field process up to standard, floor space is little, engineering construction investment is few, and operational management is flexible, rate when improve oily water treatment operation up to standard.Overcome organic pollutant efficiency in existing biochemical processing process process oily(waste)water low, the deficiency of the requirement of oil-contaminated water of oil field process up to standard cannot be met.
The technical solution used in the present invention is: the comprehensive biochemistry pool of a kind of dynamic multi-level A-O, comprises pond body; Rectangular pond body is divided into five parts laterally across four lattice partition walls, pond body is longitudinally divided into four parts by three partition walls, pond body is divided into 20 intervals, each interval internal upper part is equipped with combined stuffing, wherein every bar is laterally all connected by gallery in five adjacent intervals, four intervals of high order end are equipped with feed-water end, four intervals of low order end are equipped with water side, the interval bottom of high order end four is equipped with submersible agitator and perforated pipe aerating regulation device, and remaining all interval bottom is equipped with air diffusion aerator.
The invention has the beneficial effects as follows: the present invention combination can adopt different biochemical processing process when different quality, water yield change, in process oily(waste)water, organic pollutant efficiency is high, meet the requirement of oil-contaminated water of oil field process up to standard, floor space is little, engineering construction investment is few, operational management is flexible, rate when improve oily water treatment operation up to standard.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the vertical view of Fig. 1.
Embodiment:
As shown in Figure 1 and Figure 2, the comprehensive biochemistry pool of a kind of dynamic multi-level A-O, comprises pond body 1; Rectangular pond body 1 is divided into five parts laterally across four lattice partition walls 4, pond body 1 is longitudinally divided into four parts by three partition walls 5, pond body 1 is divided into 20 intervals, and each interval internal upper part is equipped with combined stuffing 6, realizes aerobic microbiological and anaerobion in filling surface biofilm.Wherein every bar is laterally all connected by gallery in five adjacent intervals, four intervals of high order end are equipped with feed-water end 3, four intervals of low order end are equipped with water side 9, the interval bottom of high order end four is equipped with submersible agitator 2 and perforated pipe aerating regulation device 7, and remaining all interval bottom is equipped with air diffusion aerator 8.Submersible agitator 2 realizes mixing functions, carries out homogenization treatment to oily(waste)water, increases water body turbulent flow simultaneously, increases the mass transfer process of mycoderm and water pollutant; Submersible agitator 2 is arranged on waterpower dead angle place in pond, by arranging submersible agitator 2, reduces the impact at waterpower dead angle.
During use, oily(waste)water and active sludge are introduced the present invention, open aerator and submersible agitator 2, for the microorganism in active sludge in the surperficial biofilm of combined stuffing 6.Oily(waste)water can be introduced after completing biofilm continuously and carry out biochemical treatment.According to the difference of sewage quality, organics removal object is different, and water quality, water yield impact load difference, can when not changing existing technique, can dynamic implement A-O in the present invention
