Description
Technical field
The invention belongs to the technical field of water treatment, in particular to a kind of preparation method of the Industrial Wastewater Treatment medicament for sewage.
Background technology
Sewage disposal technology has a very important role to water saving, the problem such as energy-conservation, but also affects to environment in the use procedure of sewage treatment drug simultaneously.In cooling water system, water temperature is higher than under the various occasions of envrionment temperature, and the fouling of the inorganic salt such as calcium carbonate can bring serious consequence.In recent years, in water treatment field, the water technology of using basic, non-adjust ph is growing, wherein adds corrosion-mitigation scale-inhibition medicament, low-phosphorous, without phosphorus formula application more and more extensive, without phosphorus Green Water treatment agent has become the hot subject of domestic and international water conditioner research aspect.Scientific utilization water treatment agent can effectively protection against corrosion and prevent fouling, thus the utilization ratio of raising equipment and water and reach the object of saving water source and the energy.
In addition, in various water system, inevitably there are various source of pollution, particularly some microorganisms are as bacterium algae, can spread by large-scale breeding, havoc water quality, and produce great corrosion failure effect to the container of storage of water system.
Current, environment protection has become the problem of World Focusing, and the emission request of industrial sewage is strict; country takes corresponding compulsory measure; seek a kind of effective sewage-treating agent, can reach sewage discharge requirement after can making sewage disposal, be numerous enterprises urgent need to solve the problem.
Chemical precipitation method is extensively used in sewage disposal, it in waste water, adds some chemical agent make it and Pollutants in Wastewater generation chemical reaction, form the solid product of indissoluble, then carry out solid-liquid separation, thus a kind of method of removing water pollutant.At present in some industries, as black water, oil-containing wastewater, dyeing waste water, paper waste etc. the medicament that adopts, poor processing effect, settling velocity are slow, and medicament expense is higher, and some enterprise also causes equipment heavy corrosion.
Colliery aborning, produces a large amount of black waters, if do not processed in time will cause severe contamination to these water.The process of existing slime water treatment method many employings adding medicine, polyaddition aluminum chloride or calcium chloride and polyacrylamide coupling in black water, precipitation is administered.Owing to introducing chlorion in a large number, thus cause equipment heavy corrosion.
Oil extraction in oil field factory recovered water is with crude oil from reservoir exploitation out, not only crude oil is carried in waste water, the various salt in stratum and gas is also flow in the oil reservoir of High Temperature High Pressure, in oil recovery process, from stratum, carry out many suspended solidss again, therefore, the feature of oil field extracted water be not only COD and oil-contg high, and temperature is high, salinity is high.Many employing dosing sedimentation and filtration methods process now, dosing mostly is polymeric aluminum, and ubiquity problem is that treatment effect is bad.
Be in the patent of 201010591583.1 at application number, disclose a kind of sewage-treating agent, use this treatment agent process trade effluent, it comprises zeolite powder, wilkinite, 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 disclose a kind of preparation method of sewage-treating agent, comprise the following steps:
(1) zeolite powder, wilkinite is taken according to the above ratio, hydrochloric acid, ferric sulfate, magnesium sulfate, kaolin;
(2) zeolite powder is put into the roasting of High Temperature Furnaces Heating Apparatus 500-600 degree, 20 minutes, be cooled to about 100;
(3) by the zeolite powder of high-temperature roasting and wilkinite, ferric sulfate, magnesium sulfate, kaolin puts into reactor mixing and stirring.
In the patent of application number 201110355989.4, Waste water treatment medicament is Al-Fe-Mg compound, and wherein Al3+ accounts for 30 ~ 40 parts, Fe3+ accounts for 20 ~ 30 parts, and Mg2+ accounts for 30 ~ 40 parts, also has a small amount of Mn2+ and lithopone, Mn2+ can use MnS04, accounts for 5 parts; Lithopone accounts for 5 parts, and Al3+ can add with Tai-Ace S 150 [Al2 (SO4) 3]; Fe3+ can add with [Fe2 (S04) 3]; Mg2+ can add with magnesium sulfate (MgSO4); Lithopone is the mixture of zinc sulphide and barium sulfate, and molecular formula is: ZnS+BaS04, and ratio is 3:7.
Compound method adopts general method Homogeneous phase mixing to form.(about 15 minutes) the whole dissolving that at room temperature stir can use.Use temperature is at 5 DEG C ~ 50 DEG C.
The ultimate principle of disposing of sewage is destroyed by the colloid in sewage.Exist in colloidal state containing a large amount of suspended substance, emulsification etc. in sewage.Use medicament of the present invention colloid surface charge neutralization in sewage can be fallen, thus destroy colloidal suspended substance and emulsification etc., make suspended substance rapid precipitation.
This Waste water treatment medicament is applicable to black water, oily(waste)water, dyeing waste water, paper waste, chemical industry and municipal effluent etc.After adding this medicament in sewage, suspended substance flocculates at once, and the alumen ustum of generation is large, and fast, efficiency is high, and Floc strength is high, and hydrophobic performance is good, is beneficial to press filtration for precipitation.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 percent of other medicament expenses.
After this chemicals treatment, the pH value of solution is similar to neutrality 6.5 ~ 8.5, not containing Cl-ion, when after process Water circulation, effectively can protect the steel construction in aqueous systems, make it exempt from corrosion, therefore can reduce a large amount of equipment maintenance costs every year.This Waste water treatment medicament purity is high, inclusion-free, without dust, the aqueous solution is as clear as crystal.This medicament nontoxicity, on operator without impact, the problems such as the rear water non-secondary pollution of process.
Existing water technology processes objectionable impuritiess such as the heavy metals in trade effluent, and a good removing effect can not be reached for the objectionable impurities in waste water except heavy metal, deposit the problem being difficult to eliminate objectionable impurities when especially processing industrial circulate water.In existing wastewater treatment also there is the problems such as poor processing effect, settling velocity is slow, cost is high, equipment heavy corrosion in institute's with medicament.
