Abstract
The invention discloses a cyanide breaking device for cyanide-containing wastewater treatment, which is equivalent to third time cyanide breaking. A conventional cyanide breaking method comprises the following steps: collecting the cyanide-containing wastewater, carrying out the cyanide breaking treatment for once to twice, and then, adding the cyanide-broken wastewater into a comprehensive wastewater pool, and directly treating the comprehensive wastewater. The cyanide breaking device is used for carrying out the cyanide breaking treatment once in the treatment process of comprehensive wastewater, namely, the cyanide breaking treatment is carried out in a 1# reaction tank. The cyanide breaking device disclosed by the invention has the advantages of ensuring that the comprehensive wastewater contains no cyanide before chemical precipitation in the treatment process of the comprehensive wastewater, enabling the treated heavy metal content and the cyanide content to meet the standard stably, and effectively reducing organic matters and COD (Chemical Oxygen Demand) content; since the cyanide breaking position is selected in the 1# reaction tank, no additional reaction tank is needed, thus both space and saving equipment investment are saved.
Description
Technical field
The invention belongs to technical field of waste water processing, be specifically related to the broken cyanide device that a kind of cyanide wastewater is processed.
Background technology
The broken cyanide method that existing cyanide wastewater is processed, when running into the factor such as the wastewater collection pipeline is aging, human negligence, the cyanogen that is difficult to avoid a small amount of is leaked in the comprehensive wastewater pond.After cyanogen is leaked to the comprehensive wastewater pond, because rear road does not have the device of broken cyanide, very likely cause exceeding standard of heavy metal content, cyanogen content, environment is caused to very large harm.
Consider from environmental angle, need to be improved the method for broken cyanide.
Summary of the invention
For the problems referred to above, the objective of the invention is the cyanogen in comprehensive wastewater pond is abolished fully.
The technical solution adopted in the present invention is: the broken cyanide device that a kind of cyanide wastewater is processed comprises and the position of comprehensive wastewater broken cyanide cyanogen contained in comprehensive wastewater thoroughly being abolished.
The invention has the beneficial effects as follows: with existing technology of only waste water high containing the cyanogen amount being carried out to independent broken cyanide, compare, advantage of the present invention is to carry out again broken cyanide when comprehensive wastewater is processed, the cyanogen of leakage is all abolished, while guaranteeing wastewater treatment containing cyanogen figureofmerit, heavy metal content index stably reaching standard.Because comprehensive wastewater is very low containing the cyanogen amount, the amount of the clorox added is very little, extremely limited to the cost increase of wastewater treatment.
The accompanying drawing explanation
Fig. 1 is apparatus of the present invention position views.
Fig. 2 is apparatus of the present invention scheme of installations.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment only is not used in and limits the scope of the invention for the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
As shown in accompanying drawing 1,2, the broken cyanide device that a kind of cyanide wastewater is processed, be that the cyanogen be leaked in the comprehensive wastewater pond is abolished fully.A variety of causes is leaked to the cyanogen in the comprehensive wastewater pond, though content is not high, very harmful, not only causes cyanogen content to exceed standard, and more can make heavy metals exceeding standard due to the complexing action of cyanogen, and unique effective way is that cyanogen is all abolished.
According to the requirement of various heavy metal precipitations, by PH meter, frequency transformer, volume pump, add appropriate acid or alkali in the 1# reaction tank, PH is adjusted to processing requirement; By ORP meter, frequency transformer, volume pump, add appropriate clorox in the 1# reaction tank, by setting the parameter of ORP instrument, the input amount of clorox is just in time abolished cyanogen, if in waste water without cyanogen, instrument can reduce the work output of this volume pump automatically, can not cause that the chlorine residue in waste water is too high.Whether check waste water is containing cyanogen, available two kinds of methods: data analysis, remaining cyanogen precise quantitative test strip.ORP instrument parameter setting, need determine according to practical situation.
Claims (3)
1. the broken cyanide device that a cyanide wastewater is processed is characterized in that: through separately to cyanide wastewater one to the secondary broken cyanide, in " 1# reaction tank ", comprehensive wastewater is carried out to the position of a broken cyanide again.
2. the broken cyanide device that a kind of cyanide wastewater according to claim 1 is processed is characterized in that: described " 1# reaction tank " is the position of broken cyanide for the third time.
3. the broken cyanide device that a kind of cyanide wastewater according to claim 1 is processed is characterized in that: one of intrinsic reaction tank that described " 1# reaction tank " is cyanide-containing waste water treatment system is not the reaction tank increased in addition.
