Abstract
The present invention adopts the processes of acidification, adsorption and oxidation, etc. to treat waste water resulted from production of chloroisocyanuric acid compound. After having been treated said waste water contains NaCl or KCl which can be used as raw material for producing NaOH or KOH by using electrolysis method, and the adsorption resin used for treating waste water can be regenerated by using NaOH or KOH dilute solution, and the eluent for regenerating resin contains cyanurate which can be recovered and used for producing chloroisocyanuric acid compound.
Description
With the cyanuric acid is in the production process of basic raw material production chlorated fulminuric acid compounds such as trichloroisocyanuric acid, DICHLOROISOCYANURIC ACID, Surchlor GR 60, potassium dichloroisocyanurate, discharges a large amount of processing wastewaters.
This waste water contains dissolved chlorated fulminuric acid compounds, alkali metal chloride, free chlorine and other chlorine-containing compounds etc., existing treatment technology to this waste water is that this waste water is carried out biochemical treatment, makes chlorated fulminuric acid compounds wherein be decomposed into NH
3, CO
2Deng small-molecule substance, then waste water is effluxed.Handle with such method, chlorated fulminuric acid compounds in waste water just can not be recovered utilization, and in waste water dissolved alkali metal compound such as sodium-chlor because concentration is lower, evaporating and concentrating process with routine reclaims, and also is irrational economically.Therefore can consider the waste water of this sodium chloride-containing is directly utilized.For example, the enterprise that produces the chlorated fulminuric acid compounds mostly is the enterprise that produces sodium hydroxide and chlorine, and these two kinds of materials are also produced the main raw material of chlorated fulminuric acid compounds just.And caustic soda and chlorine are produced by raw material with sodium-chlor.Therefore, the waste water of sodium chloride-containing just can directly use as raw material, and does not need concentration.But because the regulation of manufacturing process, the contained nitrogenous compound (in amino nitrogen) of salt solution that is used for producing sodium hydroxide and chlorine does not allow to surpass an extremely low concentration (as 2mg/L).And in chlorated fulminuric acid compounds processing wastewater, contained cyanuric acid and salt thereof is such class nitrogenous compound just just, therefore, as realizing to produce the electrolytic process that the NaCl waste water reclamation is used to produce sodium hydroxide and chlorine that contains of chlorated fulminuric acid compounds, must remove nitrogenous compound (cyanuric acid and salt) wherein.
The present invention proposes, a kind of exactly method that can remove nitrogenous compound in the wastewater from production of chlorated fulminuric acid effectively.
Fig. 1 is waste water produced by chloro-isocyanuric acid production processing technological flow figure.
Technological process is described below:
The processing wastewater that discharges from the production equipment of chlorated fulminuric acid compounds is at first used the HCl solution-treated, making wherein, the chlorated fulminuric acid compounds is decomposed into cyanuric acid, again with the adsorption column of this waste water by the filling macroporous adsorbent resin, employed polymeric adsorbent has the selection adsorption for cyanuric acid, cyanuric acid in the waste water almost can all be adsorbed on the resin, and effusive waste water just becomes the waste water that does not contain cyanuric acid from polymeric adsorbent.The resin that has adsorbed cyanuric acid can use NaOH, KOH dilute solution backwash and regeneration, contains cyanurate in the elutriant, recyclablely is used to produce the chlorated fulminuric acid compounds.In order further to remove other contained in waste water nitrogenous compounds such as organic ammonium salt etc., also must add NaOH or directly handle waste water with chlorine with clorox, make nitrogenous compound oxygenolysis such as organic ammonium salt become free ammonia.At last, use free ammonia in the air scavenging waste water again.Like this, just do not contained the waste water of any nitrogenous compound, just purified weak brine, such weak brine can be used in conductization salt solution in the chlor-alkali production factory.To produce trichloroisocyanuric acid is example, and one ton of trichloroisocyanuric acid of every production can reclaim 10～12 tons of weak brines that contain NaCl about 8～9% from waste water, roll over NaCl about 1 ton (in 100%).In addition, also saved 10～12 tons of water of productive use, the process water rate of recovery is reached more than 90%, wastewater discharge reduces more than 80%.Have good economic benefit and environmental benefit.
Treatment process proposed by the invention can be narrated by following example:
Get the waste water that discharges when 1000ml produces trichloroisocyanuric acid, wherein contain dissolved NaCl 80～100g, trichloroisocyanuric acid 3～5g, trace contain ammonia organism such as ammonia amine, and the pH of solution is 3.5.HCl solution to this waste water adding 10～25ml 30% leaves standstill after stirring, again by filling the resin column of 50～100ml macroporous adsorbent resin.Polarity or the strong Polar Adsorbent Resin of employed polymeric adsorbent for adopting polyacrylamide or polyvinyl pyridine compounds and other linking agent copolymerization, waste water is 50～150ml/min by the speed of resin column.Clorox 20～the 50ml that adds available chlorine 8～12% after the wastewater collection of discharging from resin column, under whipped state, react 5～20min after, bubbling air bubbling 10～20min, waste water after treatment contains NaCl concentration 7～9%, closes the ammonia nitriding compound (with NH
3-N meter)≤2mg/L.
Adsorb the NaOH solution 150～250ml backwash and regeneration of saturated resin column with concentration 3～6%.Take off and contain cyanuric acid sodium salt 7～11g in the washing lotion.
Claims (4)
1, a kind of method of handling waste water produced by chloro-isocyanuric acid production.Its treatment scheme by spent acid divide separate, resin absorption, oxygenolysis, air scavenging and resin take off and washing regeneration and form.
2, the method for claim 1, its characteristic be with HCl solution-treated waste water produced by chloro-isocyanuric acid production, makes that dissolved chlorated fulminuric acid compounds is decomposed into chlorine and cyanuric acid in the production.
