Abstract
The invention discloses an acid waste water treating agent. The acid waste water treating agent comprises the following raw materials in percentage by weight: 30-35% of soda lime, 35-45% of limestone, 10-30% of sodium silicate, and 5-10% of fluoccuant. The preparation method comprises the steps: stirring evenly the raw materials according to the formula, then crushing to be particle size of 100-150 meshes, and tabletting. With the acid waste water treating agent, the neutral reaction rate can be properly slowed down in treating waste water, and the possibility of injuring an operator due to flashing of acid liquor caused by heat generated during severe reaction can be reduced; iron ions in the acid liquor can be extracted during reaction process; and dust can not be produced in the process of treating the waste water, thereby being incapable of influencing the health of the operator, and being environment-friendly.
Description
Technical field
The present invention relates to the waste water conditioner technical field, the acid-bearing wastewater treatment agent that produces in especially a kind of steel work production process.
Background technology
Water conditioner refers to the chemical agent for water treatment, is widely used in the industries such as chemical industry, oil, light industry, daily use chemicals, weaving, metallurgy, environmental protection and printing and dyeing, to reach the purpose of waste water reuse and control pollution of waterhead.
Steel work will be through surface treatments such as overpickling, phosphatizations in the course of processing, and inevitably generation contains acid waste liquid, and not treated just discharging pollutes the environment and water body if these contain acid waste liquid.The steel work acid-bearing wastewater treatment agent poor processing effect that market is commonly used, expense is high, even causes the equipment heavy corrosion.
Summary of the invention
The technical problem to be solved in the present invention is to provide the waste water conditioner in a kind of steel work production process, has suitably slowed down neutralization reaction speed when processing waste water, has reduced because the violent heat that produces of reaction causes acid solution to splash and hurts operator's possibility; Can also extract the iron ion in acid solution in reaction process; And process in the waste water process and can not produce dust, can not exert an influence to operator's health; Environmental protection.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of acid-bearing wastewater treatment agent, and raw material is comprised of following material by mass percentage: soda-lime 30～35%, Wingdale 35～45%, water glass 10～30%, flocculation agent 5～10%;
The preparation method is: being crushed to granularity after according to formula, raw material stirring being mixed is compressing tablet after 100～150 orders.
Preferred raw material is comprised of following material by mass percentage: soda-lime 32%, Wingdale 40%, water glass 20%, flocculation agent 8%.
A kind of in poly-silicic acid, PFSC, poly-ferric sulfate chloride or bodied ferric sulfate of flocculation agent, or be this area routine flocculation agent.
Poly-silicic acid is a kind of anionic flocculant, its molecular formula (H
2SiO
3)
n
The main component of Wingdale is calcium carbonate, reaction principle: CaCO
3+ 2H
+=Ca
2++ CO
2+ H
2O
In soda-lime, the mass content of sodium hydroxide is 3%, and the mass content of calcium oxide is 78%, and the mass content of water is 19%.
The soda-lime main application is to reduce acidity; Water glass can consume the hydrogen ion in acid solution, and produced simultaneously silicic acid has again throwing out to iron ion.
Can not produce dust when processing waste water, can not exert an influence to operator's health, free from environmental pollution.And adopt this medicament to compare with lime with adopting Wingdale, suitably slowed down neutralization reaction speed, thereby reduced because the violent heat that produces of reaction causes acid solution to splash and hurts operator's possibility.In addition, silicic acid can also extract the iron ion in acid solution.
Particle after pulverizing is made compressing tablet by tabletting machine, and the wafer-like solid reacts milder than mealy solid particle with acid solution, and reacts completely, and prevents from reacting too acutely producing splashing of acid solution.
Medicament of the present invention is to have adopted two kinds of forms to process acid solution, a kind of form is to utilize water-soluble material such as the sodium hydroxide in soda-lime, another kind is exactly to adopt water-fast material such as calcium oxide, calcium carbonate, material soluble in water is different from the speed of response of acid solution with material not soluble in water, by rational proportion of the present invention, neutralization reaction is namely steadily carried out again fast.This reagent consumption acid, reduced the acidity in the acid solution, also reduced simultaneously the risk that the operator is damaged.
Adopt the beneficial effect that technique scheme produces to be: acid-bearing wastewater treatment agent of the present invention has suitably slowed down neutralization reaction speed when processing waste water, has reduced because the violent heat that produces of reaction causes acid solution to splash and hurts operator's possibility; Can also extract the iron ion in acid solution in reaction process; And process in the waste water process and can not produce dust, can not exert an influence to operator's health; Environmental protection.
