Description

Gas generator phenolic wastewater treatment system

Technical field

The utility model belongs to coal gas producer phenol water-treatment technology field, and in particular to a kind of gas generator is useless containing phenol Water treatment system.

Background technique

The phenol wastewater of gas station is by groups such as the harmful substances such as phenols, cyanide, tar, suspended matter, sulfide, ammonia nitrogen At wherein phenols is based on monohydric phenol, and with phenol content highest, secondly p-cresol, water containing phenol are mainly derived from coal there are also between The condensed water and water seal water of indirect cooler in gas purification process, wherein the production quantity of the condensed water containing phenol depends on gasification of coal Matter and used gasification process.One 3.2 meters of two stage type gas generating furnace, daily output phenol water are 6 tons, and phenol water is generally stored in In the phenol pond of 3.5 meters of depths, processing form is varied but costly, and the requirement of environmental protection administration is not achieved.

In decades, how thoroughly to administer phenol-containing wastewater is always the difficult problem of environmental protection for perplexing gas station, those skilled in the art Although member gropes to some effective processing methods, certain effect is achieved, there are still many shortcomings. Existing dephenolization treating method generally has following several:

Steam chemistry dephenolize method: heating phenol-containing wastewater with strong high-temperature steam, with steam after evaporating the phenol in sewage Evolution, being then passed through lye again and absorbing becomes sodium phenolate, to achieve the purpose that dephenolize.The method is easy to operate, and investment is also less, But steam consumption quantity is larger, and dephenolize efficiency is not ideal enough, typically up to the purpose less than thorough improvement.Northeast factory once used at the method Manage phenol-containing wastewater, after rest because steam consumption quantity is too big.

Steam dephenolize method: phenol-containing wastewater being heated, evaporates phenol with vapor, then this part steam containing phenol is passed through Producer furnace bottom is mixed into air as gasifying agent and uses, in furnace phenol at high temperature combustion decomposition at CO₂And H₂O is finally reached The purpose of dephenolize.Its shortcoming is that this method can only remove low boiling point phenol system object, and energy consumption is larger, and 1 ton of sewage of every evaporation about needs to fire Equivalent 180 kilograms of coal or so of the mark of material.Inner Mongol factory once used this method to handle phenol-containing wastewater, because energy consumption is high and gas burner furnace bottom is full It is difficult to control and deactivates with temperature.

Incineration method: spraying into incinerator for phenol-containing wastewater, aoxidizes phenol organic matter at a high temperature of 1100 DEG C or so Reaction, ultimately generates CO₂And H₂O discharge, this method simple process is easy to operate, but energy consumption is larger, it is every burn 1 ton of phenol wastewater its Cost is about at 1200~1500 yuan.It is using incineration method processing phenol-containing wastewater critical defect once careless manipulation, under furnace temperature Drop, often will cause incomplete combustion, easily formation secondary pollution.

Solvent extraction dephenolize method: point extraction and desorption two parts extract phenol first with extractant from sewage；Contain Phenol extraction agent contacts with each other with lye again, and the phenol in extractant is reacted with alkali generates sodium phenolate, which is a desorption process. Using this kind of dephenolization method treated water outlet still containing the phenol of 100-200mg/L, be unable to direct emission, and the loss of extractant It will cause sewage emulsification, and form secondary pollution.In addition this method must use efficient extractant and alkali, operating cost compared with It is high.

Resin dephenolize method: including adsorbing and desorbing, with the phenol in resin adsorption waste water, then being desorbed with lye, raw At phenol sodium, this method technical process is complex, and the factor for influencing dephenolize efficiency is more, and operating cost is relatively high.

Sulfonated coal absorption method: the method adsorbs phenol with sulfonated coal polar group, is then absorbed with lye and forms sodium phenolate dephenolize, Sulfonated coal absorption is intermittently to carry out, and completing one cycle includes adsorbing and regenerating two links.The major defect of the method is The suction phenol amount of sulfonated coal is too low, and adsorption cycle is too short, and parsing, regeneration are also relatively difficult.Northeast factory once used the processing of this method to contain Phenol sewage is finally abandoned because adsorption rate reduces too fastly.

Biochemical method: carrying out biochemical treatment to phenol-containing wastewater is culture microorganism, and utilizes microorganism by the phenols in sewage H is resolved into organic matter digestion absorption₂O and CO₂.Biochemical method requires the sewage quality for entering biochemistry pool more stringent, coke in sewage The organic concentrations such as oil and phenol may not exceed the concentration that microorganism can bear, and otherwise, need just to can enter after dilution of sewage Biochemistry pool just limits processing water in this way.Microbial acclimation is relatively difficult simultaneously, and influent concentration is exceeded, environment temperature is uncomfortable Preferably, all it is easy to the existence of restriction micro-organisms.Northeast factory once used biochemical method to handle phenol-containing wastewater, since condition requires strictly To keeping its processing cost quite high.

Currently, influence and restrict gas station phenol-containing wastewater conventional treatment method popularization and application factor mainly have it is following several Point: 1, in addition to steam dephenolize method and incineration method, remaining requirement of several processing methods to sewage disinfection treatment is all very stringent, and from Body technique is also more complicated, once invests larger, is difficult to bear for some middle-size and small-size gas stations；2, by itself dephenolize work The operating cost of the influence of skill and dephenolize efficiency requirements, conventional treatment phenol-containing wastewater method is relatively high；3, in addition to incineration method, The purpose of remaining several method is intended to the phenolic substances in removal sewage, but the water after dephenolize is not pure water body yet, because Even having reached discharge standard for the amount containing phenol in water after processing, this water also can not necessarily be discharged, this will also be regarded in water Whether the content of other organic compounds, inorganic salts etc. reaches depending on discharge standard.Therefore, be badly in need of develop one kind can be extensive It promotes, the phenol water treatment system of high treating effect.
