Description
Technical field
The present invention relates to the environmental pollution treatment technology field, specifically, relate to a kind of with raw coal fixed bed of sorbent purification mink cell focus Technology of Sewage.
Background technology
Mink cell focus is the important component part of energy utilization in this century, need develop heavy oil resources energetically to satisfy increasing of energy demand.Along with the continuous development of petroleum industry, the organic contamination that oil causes becomes the focus that people pay close attention to gradually.Process for treating oil field sewage divides technically, can be divided into physics method, chemical method and biological process.At present, less to the treatment technology report of heavy oily water in the world, more report concentrates on the removal aspect to natural organic matter in the water.The common effective ways that natural organic matter in the water is removed comprise: enhanced coagulation, charcoal absorption, ozone oxidation, ozone+biological activated carbon, reverse osmosis and nanofiltration etc.; That the conventional sewage treatment process measure of domestic main oilfield comprises is settlement separate, the polymer-bearing waste-water treatment technology of coarse separation, scale inhibitor, air supporting choosing, cyclonic separation, filtering separation, filter core separation, oxidation pond, coagulant precipitation and efficient pressure oil eliminator etc., yet, these technologies can not satisfy the mobility characteristics, and the existing sedimentation in oil field, filtration process can't be with the oil ingredient effectively catching in the sewage.
Summary of the invention
The present invention is directed to existing mink cell focus sewage treatment process bulky, can not satisfy movability, and the existing sedimentation in oil field, filtration process can't propose the problems such as oil ingredient effectively catching in the sewage a kind of raw coal fixed bed of sorbent of utilizing and dynamically handle the mink cell focus Technology of Sewage continuously.
Technical scheme of the present invention is: a kind of raw coal fixed bed of sorbent purifies the mink cell focus Technology of Sewage, and its step is as follows:
1) filler is made: raw coal is carried out fragmentation, sieve out coal particle as filler with standard sieve through vibrator;
2) filling: the filler that sieves out is packed in the fixed bed of sorbent;
3) activation: cycle through fixed bed of sorbent with deionized water and activate;
4) dynamic adsorption: mink cell focus sewage carries out dynamic continuous adsorption by fixed bed of sorbent, finishes the processing of sewage.
Preferably: described filler median size is 1.5-2.5mm.
Preferably: the pH regulator of described mink cell focus sewage is 4-6.
Preferably: described activation step is for extracting the pH value deionized water identical with mink cell focus sewage, by raw coal sorbent material filler, and controlling flow aquifer yield 8-12mL/min simultaneously, and vibrate fixed bed of sorbent removal bubble wherein with vibrator; After the end, the residual water in the fixed bed of sorbent is discharged by suction unit.
Preferably: soak time is 20-60min in the described activation step.
Preferably: mink cell focus sewage is above in the described dynamic adsorption step carries out dynamic continuous adsorption to the streaming mode by fixed bed, and flow guarantees 0.9mL/min, and treatment temp is 15 ℃-25 ℃.
Preferably: described fixed bed of sorbent is that the upward flow formula is arranged fixed bed, is the columnar structure of inner hollow, and filler is housed in the cavity; The adsorption column bottom is provided with water-in, and bottom sides is provided with the sorbent material overside port, and the water-in top is provided with water distributor; The adsorption column top is provided with water outlet.
Preferably: described absorption fixed bed is by peristaltic pump controlling flow aquifer yield.
The invention has the beneficial effects as follows: the present invention selects for use and cheaply obtains easy raw coal and replace sorbent material such as gac as the fixed bed filler, can directly act as a fuel after adsorbents adsorb is saturated.The operation of dynamic adsorption post is simple, and cost is lower; Thermal value was bigger when the raw coal behind the adsorbed oil was done fuel.Therefore, the present invention has that raw material sources are abundant, technology is simple and practical, and treatment unit can move continuously, plurality of advantages such as energy consumption is lower, environmental friendliness.The present invention can be used for handling means such as sonochemistry, warm wash and handles a large amount of mink cell focus sewage that produce in the mink cell focus contaminated soil process.Raw coal directly applies to oily water treatment and has very high novelty, need not to consider that technologies such as back flushing come problems such as reproducing adsorbent and held stationary bed processing power.Utilize in the water polymkeric substance caused adheres to filter material surface and mink cell focus easily strengthen filtrate with the coal-fired characteristics that absorption takes place net calorific value.Work design of the present invention is ingenious, can provide new approaches for effective purification of field joint stations high density oily(waste)water.The processing of place mink cell focus sewage be need not the adding of emulsion splitter, both reduced to produce burden, avoided strong corrosion and fouling again the hardware pipeline.
