Description
Technical field
The invention belongs to sewage-treating agent and preparation method thereof.
Background technology
At present, the treatment process of polluting for water is mainly method of chemical treatment, by throwing in drug treating water pollutant.Because water pollution species is many and mix, and therefore the main water conditioner function singleness using now must distinguish the various medicaments such as boss's flocculation agent, inhibiter, sterilant, processing technological flow complexity in water treatment system.Equipment is many, operating process complexity, added amount of chemical is large, expense is many, and can mutually resist by various chemical reactions between plurality of reagents, cause drug effect to reduce, at the current flocculation agent for sewage disposal, general of most popular PAC (polymerize aluminum chloride) exists the polymerization degree large not, a little less than flocculation bridge formation ability, the problems such as water outlet muddiness and hydrolysis reaction are unstable, different Sewage Environments can produce larger impact to throwing out, the effect of same flocculation agent under different Sewage Environments can differ greatly, the wherein temperature of water body, pH value and dirty concentration have the greatest impact to flocculating effect, general flocculation agent is difficult to adapt to different sewage conditions, therefore carrying out in sewage treatment process, need detect at any time water temperature and pH value, carrying out manual shift to treatment agent subject range just can make reaction proceed, thereby cause technical process complexity, simple to operate loaded down with trivial details.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of high stability sewage-treating agent.
Another one technical problem to be solved by this invention is to provide above-mentioned a kind of high stability sewage-treating agent and preparation method thereof.
The technical scheme of technical solution problem of the present invention is: a kind of high stability sewage-treating agent and preparation method thereof, comprises following material and weight part:
Citric acid 10-15
Sodium carbonate 50-70
Magnesiumcarbonate 10-15
Iron trichloride 8-20
Calcium oxide 7-20
Polyacrylamide 10-15
The particle diameter of above-mentioned various materials is 100-500 order, and is powder solid dosage.
Preparation method of the present invention is: by citric acid and sodium carbonate uniform stirring mixing 40-60 minute, add again magnesiumcarbonate, uniform stirring mixing 120-200 minute, add again iron trichloride, uniform stirring mixing 30-60 minute, then add calcium oxide uniform stirring mixing 30-60 minute, then add polyacrylamide, uniform stirring mixing 30-60 minute.
The present invention is by controlling and changing the order that the inorganic polymer of different functional groups and polymer add, the condition that occurs and do not react in recombination process, reach these compositions and before adding, keep good form to distribute and stability, after adding, there is very fast form transformation and efficient cohesion flocculence.1. make respectively inorganic polymer and the polymer with different functional groups can under physical environment, keep independence and good form to distribute by adding special component, enter (after adding) after working order and can promote co-ordination between each component, produce efficient cohesion flocculence; 2. by controlling compound condition, each component is not reacted in recombination process.
The present invention compared with prior art, existing following characteristics:
High efficiency energy: the effect that simultaneously has the various medicaments such as flocculation agent, inhibiter, sterilant, reodorant in function concurrently, gather the advantage of numerous water-treated prods, the charge neutrality ability of existing poly-aluminium (PAC), there is again the sedimentation speed of Polyferric Sulfate (PFS), therefore coagulation performance is better, and the fine and close volume of removal mud is little and settling velocity is fast.Because sewage treating efficiency is high, function is complete, so process the sewage of same volume, medicament delivery amount is 1/5 left and right that has quo of Conventional Water Treatment Programs, and the running cost of sewage disposal is low.
2, environmental protection: material used is natural organic acid and inorganic mineral, inorganic chemistry synthetics, so product is nontoxic, non-secondary pollution.
3, speed is fast, water quality good: sewage disposal speed is fast, the treatment time is short, sewage is from starting to finishing dealing with, the time of whole technical process is no more than 3 minutes, and the treatment time of domestic the most frequently used PAC flocculation agent is more than 90 minutes, pool time is 30-120 minute, and sedimentation time is 120-480 minute; Processing water clarity is high, water quality good, the water of non-metallic ion shifts, and nontoxic noresidue is safe and reliable.
4, Powdered Composite: adopt special process to make the Powdered Composite of formulation, Composite brings high efficiency energy, is Powderedly convenient to product stock, packing and transportation, thereby has reduced the comprehensive cost of product.
5, basicity is high, corrodibility is little: this product basicity is higher than other aluminium salt, molysite, and erosion and corrodibility to equipment are little.In the time that sewage is carried out to throwing out, metallic cation reacts with water and can produce larger corrosive nature to equipment by a large amount of H+ ion of generation, and in HML calcium oxide can be at any time in and the H+ that exists in sewage, not only there is Coagulation aiding, and can regulate pH value, the basicity of water is increased, thereby effectively stoped erosion and the corrosion of sewage treatment process to equipment.
