Description
Technical field
The invention belongs to industrial waste acid processing technology fields, and in particular to it is a kind of for industrial waste acid processing Compound Water at
Manage medicament and preparation method thereof.
Background technique
In chemical industry manufacture, it usually needs use acids as reaction raw materials, medium or catalyst, after reaction,
After carrying out washing process, it will usually generate more industrial waste acid.Such as sulfate process titanium dioxide, hydrometallurgy (electrolysis) industry produce
Waste Sulfuric Acid, waste electrolyte out；Titanium tetrachloride, titanium white chloride, titanium sponge and chlor-alkali industry waste hydrochloric acid；Stainless steel, steel, aluminium
The plating of foil industry, the Waste Sulfuric Acid of pickling link output, Waste Sulfuric Acid/hydrochloric acid nitration mixture, waste hydrochloric acid/waste nitric acid nitration mixture；Sulphur dioxide of phosphor chemical industry
Waste phosphoric acid of output etc..Due to free acid and metallic salt containing higher concentration in these industrial waste acids, environment is caused
Biggish threat.Simultaneously because in industrial waste acid a large amount of metallic salts presence, lead to metal salt in industrial waste acid and spent acid
The difficulty of class directly recycled is larger.
The treatment process of industrial waste acid comparative maturity is at present: 1) neutralisation: acid pickle addition alkaline matter is carried out acid
Alkali neutralization adjusts liquid PH6~9 after neutralizing, and can be passed through air when necessary and carry out forced aeration, improves neutralization precipitation object cohesion speed
Degree and structure, slurry is separated by solid-liquid separation after neutralization, and filter residue slag input field is stacked, discharge after filtrate is up to standard.2) it waste acid concentration method: adopts
With traditional heating evaporation technique, acid pickle is concentrated, with the raising of acid-spending strength and temperature, a large amount of gold in spent acid
The reduction for belonging to solubility of the salt in acid can crystallize precipitation, be concentrated into after a certain concentration by necessary separation of solid and liquid, remove
The metallic salt being precipitated is crystallized, obtains certain density gelled acid, metallic salt is largely removed in acid, which can return
It goes back to factory and fresh acid collocation uses.3) three kinds of diffusion dialysis embrane method.
What present waste acid treatment method was mainly taken is the method for acid-base neutralization, but this method is in disposition spent acid
Need to consume the alkali of equivalent.Most of at present still to use single alkali process agent, single inorganic agent usage amount is big, is handling
A certain amount of other impurities are also generated in the process, and have not been able to remove the toxic looms such as the heavy metallic salt in spent acid well, are needed
Industrial waste acid is handled step by step, processing method is complicated, while also needing to consume more manpower financial capacity's material resources.
Summary of the invention
It is an object of the invention to be consumed greatly in industrial waste acid using the alkaloid substance in acid-base neutralization processing method, work
The problems such as industry waste acid treatment effect is undesirable, provide it is a kind of for industrial waste acid processing composite water treatment medicament and its preparation side
Method, the composite water treatment medicament property that the present invention is prepared are stablized, and high treating effect greatly reduces composite water treatment medicament
Dosage, and processing method is simple.
The scheme of the invention is realize in this way:
A kind of composite water treatment medicament for industrial waste acid processing, each constituent of the composite water treatment medicament and its parts by weight
Number ratio are as follows: 18 ~ 20 parts of carbide slag, 16 ~ 20 parts of conch meal, 14 ~ 16 parts of plant ash, 14 ~ 16 parts of polyacrylamide, alkyl betaine

Reduce usage amount；By modified plant ash, mixed material, polyacrylamide and the quaternary ammonium of the pretreatment compositions such as carbide slag and conch meal
Salt, alkyl betaine, sodium lignin sulfonate are mixed in high-speed mixer, coupling agent and odium stearate, polyethylene wax,
Under sodium lignin sulfonate effect, the compatibility between plant ash, carbide slag, conch meal and polyacrylamide can be promoted, improved
The stability for the composite water treatment medicament being prepared.
Plant ash, carbide slag, conch meal are alkaline matter in the present invention, and plant ash, carbide slag, conch meal have
Biggish specific surface area and there is more active site compared with multi-pore structure and surface, there is stronger adsorption capacity, in grass
Wood ash, carbide slag, conch meal can carry out acid-base neutralization with the acidic materials in industrial waste acid and form salts substances, then poly- third
It under the flocculation of acrylamide, can will be separated in the salts substances of formation therefrom solution, can remove and reach after filtering
Spent acid purified treatment effect；Heavy metal substance, the suspended particulate in industrial waste acid can additionally be adsorbed；The stearic acid of addition
Sodium, polyethylene wax have certain lubricating action, can promote compatible between carbide slag and conch meal and other material compositions
Property；Odium stearate hydrolyzes presentation alkalinity in aqueous solution, can promote the degradation of spent acid；The sodium lignin sulfonate of addition has very
Strong dispersibility can promote the compatibility between each ingredient of raw material, also have preferable sequestering power to heavy metal, promote multiple
Suction-operated of the Heshui treatment agent to the heavy metal in industrial waste acid；Quaternary ammonium salt, the alkyl betaine of addition have good
Bactericidal effect can effectively kill the microorganism contained in industrial waste acid, so that treated, waste sewage is safer.
The present invention has following good result:
1. the industrial wastewater composite water treatment medicament performance that the present invention is prepared is stablized, neutralization reaction is easily controllable, Compound Water
