Description
Technical field
The invention belongs to the technical field that water processes, in particular to the preparation method of a kind of Industrial Wastewater Treatment medicament for sewage.
Background technology
Water saving, the problem such as energy-conservation are had a very important role by sewage disposal technology, but also affect to environment during the use of sewage treatment drug simultaneously.In cooling water system, water temperature is higher than under the various occasions of environment temperature, and the fouling of the inorganic salts such as calcium carbonate can bring serious consequence.In recent years, in water treatment field, apply alkaline, not regulate pH value water technology growing, wherein add corrosion-mitigation scale-inhibition medicament, formula low-phosphorous, without phosphorus application more and more extensive, without phosphorus Green Water treatment agent has become the hot subject in terms of domestic and international water treatment agent research.Scientific utilization water treatment agent can effectively anticorrosion and prevent fouling, thus improve equipment and the utilization rate of water and reach to save water source and the purpose of the energy.
Additionally, in various water systems, be inevitably present various pollution sources, particularly some microorganisms such as bacterium algae, can spread by large-scale breeding, heavy damage water quality, and the container depositing water storage system is produced great corrosion failure effect.
Currently, environmental protection has become the problem of World Focusing, and the emission request of trade effluent is strict; country takes corresponding compulsory measure; seek a kind of effective sewage-treating agent, it is possible to sewage discharge requirement can be reached after making sewage disposal, be numerous enterprises urgent need to solve the problem.
Chemical precipitation method is extensively used in sewage disposal, and it is to add some chemical agent in waste water to be allowed to and Pollutants in Wastewater generation chemical reaction, forms the solid product of indissoluble, then carries out separation of solid and liquid, thus remove a kind of method of water pollutant.At present in some industries, the medicament used such as black water, oil-containing wastewater, dyeing waste water, paper waste etc., poor processing effect, sinking speed are slow, and medicament expense is higher, and some enterprise also results in equipment heavy corrosion.
Colliery aborning, produces substantial amounts of black water, if not being acted upon in time will result in severe contamination to these water.Existing slime water treatment method many employings adding medicine processes, and in black water, polyaddition aluminium chloride or calcium chloride are combined with polyacrylamide, and precipitation is administered.Owing to introducing chlorion in a large number, thus result in equipment heavy corrosion.
Oil extraction in oil field factory recovered water is with crude oil from reservoir exploitation out, waste water not only carries crude oil, the various salts in stratum and gas is also flow in the oil reservoir of HTHP, in oil recovery process, carrying out again many suspended solids from stratum, therefore, the feature of oil field extracted water is that not only COD and oil content are high, and temperature is high, salinity is high.The most employing dosing precipitation filtration methods process, and dosing mostly is polymeric aluminum, and generally existing problems are that treatment effect is bad.
In the patent of Application No. 201010591583.1, disclosing a kind of sewage-treating agent, use this inorganic agent to process industrial wastewater, it includes zeolite powder, bentonite, hydrochloric acid, ferric sulfate, magnesium sulfate, kaolin；Weight ratio between each component is: 1: 0.2-0.4: 1: 0.05-1: 0.3-0.4；Zeolite powder and bentonitic weight ratio are 0.7-1-0.3-1.
And also disclose the preparation method of a kind of sewage-treating agent, comprise the following steps:
(1) zeolite powder, bentonite, hydrochloric acid, ferric sulfate, magnesium sulfate, kaolin are weighed according to the above ratio；
(2) zeolite powder is put into 500-600 in high temperature furnace
Degree roasting, 20 minutes, is cooled to about 100；
(3) by zeolite powder and the bentonite of high-temperature roasting, ferric sulfate, magnesium sulfate, kaolin puts into mixing and stirring in reactor.
In the patent of application number 201110355989.4, Waste water treatment medicament is Al-Fe-Mg
Composite drug, wherein Al3+ accounts for 30～40 parts, and Fe3+ accounts for 20～30 parts, and Mg2+ accounts for 30～40 parts, the most a small amount of Mn2+ and lithopone, and Mn2+ can use MnS04, accounts for 5 parts；Lithopone accounts for 5 parts, and Al3+ can use aluminum sulfate [Al2 (SO4) 3] to add；Fe3+ can add with [Fe2 (S04) 3]；Mg2+ can use magnesium sulfate (MgSO4) to add；Lithopone is the mixture of zinc sulphide and barium sulfate, and molecular formula is: ZnS+BaS04, and ratio is 3:7.
Compound method is to use conventional method to be uniformly mixed.It is stirred at room temperature uniformly (about 15 minutes) all to dissolve and can use.Use temperature at 5 DEG C～50 DEG C.
The general principle processing sewage is to be destroyed by the colloid in sewage.Sewage exists in colloidal state containing substantial amounts of suspension, emulsion etc..The medicament using the present invention can fall colloid surface charging neutrality in sewage, thus destroys colloidal suspended substance and emulsion etc., makes suspension rapid precipitation.
This Waste water treatment medicament is applicable to black water, oil-polluted water, dyeing waste water, paper waste, chemical industry and municipal sewage etc..After adding this medicament in sewage, suspension flocculates at once, and the alumen ustum of generation is big, and quickly, efficiency is high for precipitation, and Floc strength is high, and hydrophobic performance is good, beneficially press filtration.Filter cake moisture content after press filtration is low, and quality is good.The medicament expense processing every cube of this medicament of sewage is only about 60 the percent of other medicament expenses.
After this chemicals treatment, the pH value of solution is similar to neutrality in 6.5～8.5, without Cl-ion, after processing Water circulation, can effectively protect the steel construction in aqueous systems so that it is exempt from corrosion, can reduce substantial amounts of equipment maintenance cost the most every year.This Waste water treatment medicament purity height, free from admixture, without dust, the aqueous solution is as clear as crystal.This medicament is non-toxic, on operator without impact, and the problem such as water non-secondary pollution after process.
The harmful substances such as the heavy metal in industrial wastewater are processed by existing water technology, and a good removing effect can not be reached for harmful substance in addition to heavy metal in waste water, deposit, when especially processing industrial cycle water, the problem being difficult to eliminate harmful substance.In the process of existing waste water, medicament used there is also the problems such as poor processing effect, sinking speed is slow, cost is high, equipment heavy corrosion.
