Abstract
The utility model discloses a cyanide pretreatment device. The cyanide pretreatment device comprises a reaction tank, wherein a cyanide waste liquid storage tank is communicated to a waste liquid inlet of the reaction tank, a sodium hypochlorite storage tank, a sodium hydroxide storage tank and a hydrochloric acid storage tank are communicated to a reagent inlet of the reaction tank, a first switch valve is arranged between the reaction tank and the sodium hypochlorite storage tank, a second switch valve is arranged between the reaction tank and the sodium hydroxide storage tank, a third switch valve is arranged between the reaction tank and the hydrochloric acid storage tank, and an outlet of the reaction tank is used for connecting with a sewage treatment device. According to the cyanide pretreatment device disclosed by the utility model, cyanide waste liquid is reacted with sodium hypochlorite, sodium hydroxide and hydrochloric acid in the reaction tank so as to carry out pretreatment on the cyanide waste liquid, so that the toxicity of the cyanide waste liquid is reduced, then the produced low-toxicity waste liquid is transported to a waste water treatment place for further treatment, and the damage degree to an environment caused by midway leakage can be reduced.
Description
Technical field
The utility model relates to a kind of for prussiate being carried out to the prussiate pretreating device of processing early stage.
Background technology
Prussiate is highly toxic substance, and prussiate can produce prussic acid in vivo, makes cellular respiration be subject to paralysis and causes death by suffocation.Ubiquity micro cyanide in physical environment, mainly from fertilizer and organic matter.But the prussiate of high density carrys out self-contained cyanogen industrial sewage, mainly contain the gas washing wastewater of electroplating sewerage, cyanidation gold-extracted, coke oven and blast furnace and the industry such as water coolant, some chemical engineering sewages and ore dressing sewage, synthetic rubber, fiber and dyestuff etc., contain all very high containing the cyanogen amount of cyanogen industrial sewage, toxicity is also very large, need to be transported in professional treatment plant and be processed, if but occur that in transportation the leakage meeting causes very large impact to environment.
The utility model content
The purpose of this utility model is to provide a kind of prussiate pretreating device, to reduce the cyanogen amount that contains containing the cyanogen industrial sewage.
In order to realize above purpose, the utility model adopts following technical scheme: a kind of prussiate pretreating device, comprise retort, be communicated with and be provided with the cyanide waste liquor storage tank in the waste liquid import of retort, be communicated with and be provided with the clorox storage tank in the reagent import of retort, sodium hydroxide storage tank and hydrochloric acid tank, be provided with the first switch-valve between retort and clorox storage tank, be provided with the second switch valve between retort and sodium hydroxide storage tank, be provided with the 3rd switch-valve between retort and hydrochloric acid tank, the outlet of described retort is for being connected with waste disposal plant.
Be respectively arranged with force (forcing) pump between described retort and clorox storage tank, sodium hydroxide storage tank and hydrochloric acid tank.
The utility model allows cyanide waste liquor be reacted with clorox, sodium hydroxide and hydrochloric acid in retort, cyanide waste liquor is carried out to pre-treatment, alleviate the toxicity of cyanide waste liquor, then just the low toxicity waste liquid of production can be transported to wastewater treatment place and be further processed, alleviate the destruction dynamics of leaking environment midway.
