Description
Technical field
This utility model belongs to changing waste into resources and utilizes technical field, is specifically related to one and utilizes disk desiccation machine to process height
The system of salty organic waste liquid.
Background technology
High salty organic waste liquid refers generally to COD > 10,000mg/L, salinity > 20, the waste liquid of 000mg/L, belong to extremely difficult place
The organic industry waste liquid of reason.High salty organic waste liquid is most commonly seen in pesticide synthesis industry, and this waste liquid outlet is difficult, existing process
Relatively costly, it has also become the important bottleneck of the sector sustainable development.For glyphosate, it be one be efficiently, low toxicity, wide
Compose the natural disposition herbicide after seedling that goes out, be mainly used in resistance glyphosate genetically modified crops field weeding, bare place weeding etc., the most become
Whole world yield and the pesticide species of consumption maximum.And China's glyphosate yield is according to No. 1 in the world, within 2014, reach 600,000 tons,
Jiangsu Province's yield the most up to 15.6 ten thousand tons.The watery biochemical treatment process of organic waste is not particularly suited for processing the agricultures such as glyphosate waste liquid
The high salty organic waste liquid of medicine industry, this is because the BOD/COD numerical value of this type of waste liquid is typically smaller than 2, biodegradability can be poor.
Utilize advanced oxidation processes can improve the biodegradability of organic wastewater to a certain extent, but for high salty organic waste liquid, senior
Oxidation cannot remove the salt component in waste liquid, and a large amount of salinities enter biochemical system can destroy the growing environment of microorganism, impact biochemistry
System properly functioning.Therefore major part industrial park sewage treatment plant is all specially provided with 5000-in waste water receives pipe standards
The salt index of 8000mg/L limits, and this proposes higher wanting for the Wastewater Pretreatment of the pesticide producing enterprises such as glyphosate
Ask.
In order to reduce the salinity in high salty organic waste liquid, many enterprises utilize the salt in multiple-effect evaporation technique separation waste liquid
Point, form waste salt dregs.But owing to multiple-effect evaporation operation temperature is 100-200 DEG C, it is not reaching to larger molecular organics in waste liquid
Gasification temperature, causes the most of organic poison still containing in former waste liquid in waste salt dregs.With pesticide industry abraum salts such as glyphosates
As a example by slag, according to " National Hazard refuse register " and " discriminating of hazardous waste judging standard toxic chemical content ", this kind of abraum salt
Slag belongs to HW04 class pesticide refuse, needs the hazardous waste landfill being sent to qualification to carry out solidification landfill, and processing cost is up to
3000 yuan/ton.Owing to disposal costs is the highest, many enterprises have to this type of waste salt dregs of bulk deposition, even will have virose
Waste salt dregs is sold to illegal retailer as by-product salt, and the serious threat people's is healthy.
High for high salty organic waste liquid salinity, the feature of biodegradability difference, lot of domestic and foreign scholar has carried out greatly
Amount exploratory study, main method can be divided into membrane separation process, absorption method, chemical oxidization method and burning/high-temperature decomposition etc..Its
In, membrane separation process, absorption method and chemical oxidization method are incomplete to organic degraded, it is impossible to reach the target of harmless treatment,
The purity salt that high salty organic waste liquid after process obtains through multiple-effect evaporation is inadequate, it is impossible to reuse and industrial trade, Zhi Nengzuo
Process further for danger is useless.When burning/high-temperature decomposition processes high salt bearing liquid wastes, in body of heater, easily produce the eutectic of low melting point
Body, the problem such as coking and slagging causing incinerator, make burning not to be normally carried out.
Hunan Chemical Research Institute congratulate week just, Peng Aiguo et al. is for high salty organic waste liquid pretreated waste salt dregs difficulty
Reason, the problem directly burning easily slagging scorification again, it is proposed that combine wet method dephosphorization process with thermal decomposition and process the thinking of waste salt dregs: be first
Being baked out by itrogenous organic substance in waste salt dregs first with a thermal decomposition furnace, organophosphor is now lower turn of high temperature (about 400 DEG C)
The Phos such as chemical conversion sodium pyrophosphate are present in solid salt, by the salt water dissolution after thermal decomposition, followed by dephosphorization agent by molten
Phosphorus in liquid precipitates, through filtering to obtain industrial sodium chloride solution, but, this technical finesse material initial configuration is half slag
State, hot-air directly contacts with salt slag and provides pyrolytic gasification heat, reduces the gasification steam calorific value of generation, add hot cigarette
Probability during pollutant are infected with solid salt in gas.
