Dichlorohydrin cyclization saponification in alkaline solution obtains epoxychloropropane product.Alkaline solution is usually calcium hydroxide or hydroxide
Sodium.Therefore, the technique waste water index for being produced under the production technology is as follows, COD20000 ~ 40000mg/L, TDS：250000~
300000mg/L, pH：8~10；The waste water of such high target cannot be excluded directly, it is necessary to such industrial wastewater
Posterior circle is discharged or processed after being processed to use.
Traditional epoxychloropropane waste water is using concentration, evaporation desalination, the group technology of evaporation condensate biochemical treatment.This
The shortcoming of technique is that the salt that is costly, being concentrated by evaporation for concentrating-evaporating belongs to dangerous solid waste, separately needs extra process.
Have in disclosed technology using ammonium hydrogen carbonate and calcium chloride reaction, generation calcium bicarbonate in waste water, heat resolve is produced
Raw precipitation of calcium carbonate and water, carbon dioxide, reclaim the calcium carbonate of high-purity.But the method is only applicable to cyclization saponification, and section is used
The production technology of aqua calcis, and the first step reaction generation ammonium chloride stay in water body, by reverse osmosis concentration reclaim
Ammonium chloride in contain organic matter.Therefore the water for being obtained by the processing method still can influence recycled.
In the method that the salt and recycling of water resource in epoxychloropropane waste water are utilized in the prior art, exist processing cost it is high,
Handling process it is cumbersome and exist the waste water after potential safety hazard or treatment cannot the effectively deficiency such as recycling, because
This, a kind of easy to operate, safety coefficient of design is high and processing cost is low, while enabling to processed waste water to be utilized effectively
Method be always those skilled in the art's technical barrier to be solved.
