Sewage, and the sewage etc. of generation can't artificially be handled in many cases, but directly discharge it into the Nature
In, thus to great pollution is brought naturally.
Therefore, there is shortage and be effectively treated using reagent, very big dirt can be caused to the Nature in existing wastewater from chemical industry
The problem of dye.
Summary of the invention
The present invention provides a kind of efficient process chemical industry to solve above-mentioned technical problem present in existing wastewater from chemical industry
Precipitating reagent of sewage and preparation method thereof, it can effectively locate heavy metal particles, bacterium and the stink in wastewater from chemical industry
Reason, has the characteristics that method is simple, low in cost, treatment effect is preferable and treatment effeciency is higher.
Technical solution of the present invention: the precipitating reagent of efficient process chemical engineering sewage is made of the raw material of following parts by weight,
25~30 parts of nano calcium oxide, modified 17~20 parts of potassium hydroxide, 14~15 parts of calcium carbonate, diatomite 12~15
Part, 17~20 parts of bentonite, 18~20 parts of active carbon particle, 25~30 parts of nano zine oxide, 25~30 parts of nano aluminium oxide,
8~10 parts of nano silver particles powder.
Another technical solution of the invention: the precipitating reagent preparation method of efficient process chemical engineering sewage includes the following steps,
A, by calcium carbonate, diatomite, bentonite, active carbon particle, nano zine oxide, nano calcium oxide, nano aluminium oxide
It is added in grinder and grinds, sieve with 100 mesh sieve later, obtain mixture A；
B, modified potassium hydroxide is added in mixture A, is added in stirred tank and is sufficiently stirred after mixing, stirring rate
It is 800 revs/min, time 40min obtains mixture B；
C, nano silver particles powder is added in mixture B, is added in high-speed kneading machine after mixing, is heated to 60 DEG C, stirs
It mixes after 35min to obtain the final product.
The invention has the following beneficial effects:
Preparation method of the present invention is simple, and precipitating reagent obtained can effectively precipitate the heavy metal particles in sewage, can
Water quality after improving sewage treatment, while also having effects that sterilization, deodorization；Diatomite, the bentonite energy added in the present invention
The effect of absorption heavy metal particles is enough played, and is not easy to overflow after adsorbing；It is active carbon particle that the present invention adds, nano oxidized
Zinc, nano calcium oxide can play the effect of sterilization and deodorization；In addition, the nano silver particles powder of addition, can prevent from precipitating
Agent exposure aoxidizes in air, influences sedimentation effect；It is obtained through overtesting, traditional precipitating reagent deposition efficiency is 66%, and is removed
Smelly effect is poor；And precipitating reagent rate of deposition produced by the present invention reaches 95%, and good deodorization effect；In addition, the system that the present invention uses
