Description
Technical field
The present invention relates to php slurry processing technology fields, more particularly, to a kind of sulfonation process for treating waste sludge resulted.
Background technology
Three-sulfonated mud system also becomes lignosulfonate mud system, is a kind of function admirable, the price that oil field at home generally uses
Cheap high temperature resistant type mud system is mainly used for deep drilling process when drilling depth reaches 2000-3000m or more, mesh
There is an a large amount of use in preceding oil field each at home, three-sulfonated mud system be exactly added in mud system sulfonated phenol formaldehyde resin,
The mud system that the substances such as sulfonated lignite, sulfonation tannin extract are formed.
Generated waste liquid of drilling becomes sulfonation discarded slurry, sulfonation discarded slurry to lignosulfonate mud system in use
Be mainly characterized by that water-soluble COD value is high, and coloration is big;Also contain a large amount of inorganic salts in sulfonation discarded slurry, high molecular weight
Organic compound, the heavy metal ion such as mercury, arsenic, cadmium, chromium, lead and petroleum hydrocarbon class pollutant, present sulfonation discarded slurry is all
It can not be effectively treated and reach discharge standard so that the discharge of present sulfonation discarded slurry causes local water quality, edaphic condition
It causes seriously to pollute, serious destruction is caused to local ecological environment and the ecological balance.
Invention content
For the above problem in the prior art, the present invention proposes a kind of sulfonation process for treating waste sludge resulted, solves
Sulfonation discarded slurry can not be effectively treated now, discharge standard is not achieved, water quality, edaphic condition is caused to cause serious dirt
It dye and the technical problems such as does great damage to local environment and the ecological balance.
The technical scheme is that:A kind of sulfonation process for treating waste sludge resulted, includes the following steps,
1) lignosulfonate mud is sent by grabbing device in fluidizer, by lignosulfonate mud according to 1 in fluidizer:1
~3 ratio is diluted with water, and adds suitable biological surface cleaning agent, and controlling reaction temperature is not less than 30 DEG C, fluidized reaction
15~25min;Lignosulfonate mud is first subjected to fluidized reaction, fluidized reaction can effectively go the organic pollution in lignosulfonate mud
It removes, it is best to the removal effect of organic pollution compared to microbiological treatment and other processing methods, fluidized reaction.
2) after reaction finishes, lignosulfonate mud is pumped into screening plant, the fine sand in lignosulfonate mud is removed;
By subsequent equipment damage, in addition fine sand removal in lignosulfonate mud is prevented on the one hand so that preventing fine sand by line clogging
On the one hand it is so that the effect of subsequent electrochemical reaction is more preferable, effective mitigate detaches burden so that entire technique is to sulfonation
The effect of mud conditioning is more preferable.
3) it carries out the lignosulfonate mud after desanding operation to enter in the first homogeneous tank, while adding successively in the first homogeneous tank
Enter suitable gel breaker, heavy metal chelant carries out equal qualitative response;It in this way can will be in lignosulfonate mud
4) the lignosulfonate mud that finishes of qualitative response is entered in centrifugal device and is separated by solid-liquid separation, isolated liquid phase into
Enter into buffer storage;
5) isolated solid phase enters in the second homogeneous tank, while suitable microorganism is added in the second homogeneous tank
Degradation agent carries out second homogenate reaction;Second homogenate reaction and secondary cleaning are carried out to the solid phase after separation so that separation row
The mud cake gone out not can cause environmental pollution.
6) solid phase after progress second homogenate reaction, which enters, carries out press filtration in filter-pressing device, the liquid phase that press filtration obtains enters
Into buffer storage;Liquid phase carries out precipitation caching in buffer storage, and then clear liquid is entered in micro-nano air flotation device and carried out
Air-flotation process will further ensure the clean-up performance of liquid phase in this way, not only so that subsequently more preferable to the treatment effect of liquid phase,
Follow-up precision equipment is avoided to be damaged.
7) liquid phase in buffer storage enters in the micro-nano air-flotation process unit in electric flocculation air-floating apparatus at air supporting
Reason, while a small amount of oil phase is removed by mud-scraping apparatus;Then liquid phase enter back into high-voltage pulse electric flocculation processing unit into
Row electrochemical reaction realizes the pollutant in liquid phase comprehensive decomposition and separation, the bed mud row in electric flocculation air-floating apparatus
Enter into sludge concentration tank;Liquid phase can disposably be carried out to electrolytic oxidation reaction in this way, electroreduction reacts, electrolytic flocculation is anti-
It answers, electrofloatation reaction, comprehensive separation and decomposition can be carried out to pollutant in this way,
8) liquid phase finished is reacted in electric flocculation air-floating apparatus enter in double film filters carry out double medium filtration, mistake
Part clear water after filter, which enters, is used for medicament configuration in dispensing canister, a small amount of concentrated water for filtering generation enters MVR vaporising devices
In be evaporated crystallization, the standard of environmental emission can not only be reached by handling liquid phase in this way, additionally it is possible to see the liquid phase after processing
It recycles in the art.
Further, the reaction temperature in the step 1) is 30~50 DEG C.Enable to fluidized reaction to sulfonation in this way
The treatment effect of mud is more preferable, in addition can also ensure that the energy consumption of entire process is lower in this way.
Further, the fluidized reaction time is 18~22min, while ensureing fluidization treatment effect, it is ensured that
The efficiency of fluidization treatment.
Further, the gel breaker in the step 3) is aluminium polychloride, bodied ferric sulfate or polymeric aluminium ferrum silicate
In it is one or more;
Further, the heavy metal chelant in the step 3) is xanthic acid esters or dithiocarbamates
Derivative.
Further, ceramic membrane and anti-pollution RO films are set in double film filters in the step 8).
Compared with prior art, the beneficial effects of the invention are as follows:
The present invention is optimized by the equipment to entire technological process, not only so that through the invention can be by sulphur
Change mud to be effectively treated, the liquid phase after handling can directly reach the standard of discharge, and entire technological process is opposite
More simplify, entire processing operation process is also relatively simple, and treatment effeciency is high and to the good energy-conserving effect of entire technique;Therefore,
The present invention fundamentally solves the problems, such as that lignosulfonate mud causes seriously to pollute to soil and water quality.
