Abstract
The present invention discloses one kind of Z's nanometer efficient sewage dewatering amendment. The Z's nanometer efficient sewage dewatering amendment consists of polymerized ferric sulfate 85-98 weight portions, polyacrylamide 0.5-6 weight portions, hydroxymethyl cellulose sodium 0.5-6 weight portions and nanometer material 0.5-3 weight portions. The present invention has powerful neutralizing capacity, bridging capacity and permeating capacity and thus has high sewage dewatering effect.
Description
Technical field
The present invention relates to a kind of ZShi efficient nano sludge dehydration conditioner.
Background technology
Ignore easily and be that very crucial processing unit is a sludge treatment for one in the sewage disposal, the key of sludge treatment is sludge dewatering, moisture existence form in the mud roughly has four kinds, 1, is present in interstitial water between mud granule, be called interstitial water or free-water, account for 65～85% of sludge water content; 2, be present in the kapillary between mud granule, claim capillary water, account for about 15～20% of sludge water content; 3, be adsorbed on a part of water on the mud granule, claim planar water,, have stronger surface adsorption power because mud granule is little; 4, combination water is the chemically-bonded water of granule interior, the particulate internal structure that only changes could with combined moisture from.Planar water and combination water generally account for about 10% of mud Total Water, because moisture percentage in sewage sludge is all more than 98% in the sewage disposal, so the general mud of consideration earlier concentrates, this is to reduce moisture percentage in sewage sludge, reduce the effective ways of mud subsequent disposal expense and difficulty, when moisture percentage in sewage sludge when 99.5% is concentrated to 98.5%, volume can narrow down to original 1/3, be concentrated to 95% o'clock, sludge volume only is original 1/10, the spissated dehydration of mud to as if account for 70% interstitial water of sludge water content, solid matter mainly is a colloidal particle in the mud, very strong with the avidity of water, if do not do suitable pre-treatment, make the mud particle change physico-chemical property, destroy the mud colloidal structure, reduce the avidity of itself and water, thereby improve dewatering, be difficult to reach the purpose of dehydration, adopt the dosing method at present because economical and practical, simple and convenient, and by domestic and international common employing.
The principle of dehydrating and conditioning agent is exactly to make the inorganic or organic medicament that has electric charge at mud colloid surface react with, in and the mud granule electric charge, water is separated from mud granule, make mud granule condense into big particle flco simultaneously, the quality of conditioning effect and dosing kind and quality, added amount of chemical and environmental factors etc. has substantial connection.Sludge dehydration conditioner is divided into two classes at present, and a class is inorganic medicament, comprises iron system, aluminium system, and the inorganic medicament of polymer, another kind of is the organic polymer medicament, and cationic, anionic and non-ionic type are arranged, based on polyacrylamide, and the single medicament of most employing.
Summary of the invention
The ZShi efficient nano sludge dehydration conditioner that the purpose of this invention is to provide a kind of efficient compound increases neutralising capacity and bridging ability and seepage force, makes the sludge dewatering pretreating effect good, and speed is faster, dosing still less, price is the most flat, water ratio is lower.
The present invention combines the advantage separately of inorganic polymer amendment and organic polymer amendment, (temperature, humidity) under certain condition, mix and stir the compound compound ZShi efficient nano sludge dehydration conditioner of producing by comminution by gas stream, and (temperature, pressure, humidity) is added nano material and is carried out the materialization modification and produce under given conditions, is widely used in sludge dewatering.
Its compound weight is counted:
85～98 parts of bodied ferric sulfates (PFS),
0.5～6 part of polyacrylamide (PAM),
0.5～6 part of sodium cellulose glycolate (Na CMC),
Nano material (TiO
2, ZnO, SiO
2) 0.5～3 part.
Its preferable weight is counted:
90～95 parts of bodied ferric sulfates (PFS),
2～4 parts of polyacrylamides (PAM),
2～4 parts of sodium cellulose glycolates (NaCMC),
Nano material (TiO
2, ZnO, SiO
2) 1～2 part.
Its optimum weight is counted:
92 parts of bodied ferric sulfates (PFS),
3 parts of polyacrylamides (PAM),
3 parts of sodium cellulose glycolates (NaCMC),
Nano material (TiO
2, ZnO, SiO
2) 2 parts.
ZShi efficient nano sludge dehydration conditioner according to aforementioned proportion is produced demonstrates following characteristics:
1, complementarity: brought into play the big advantage of inorganic conditioner flco intensity after compound, overcome the shortcoming that dosage is big, flco is little, brought into play the advantage that organic amendment dosage is little, flco is big again, overcome the shortcoming that flco intensity is low, price is expensive, make its conditioning performance better, cost is low.
2, synergy: composite amendment is when having complementarity, obvious synergistic effect is arranged, nurse one's health the stack that modified effect is two kinds of medicaments, dehydrating effect obviously is better than single dehydrating and conditioning agent, and consumption has only about 1/2 (method of weighted mean) of single amendment, handle reagent cost and reduce by 50%, dehydration rate improves about 10%.
3, owing to compound amendment, particularly after nano material is added modification, so raising is to the conditioning and the modified performance of mud, the avidity of colloid particulate and water is weakened greatly, mud particle physical and chemical performance is obviously improved, destroyed the colloidal structure of mud, make the easier dehydration of mud.
4, because the nano material that adds has specific surface area huge, surface energy increases, and surface atom is many, and is unsettled strong many, so very high chemically reactive is arranged itself, special very strong adsorptive power is the fabulous auxiliary agent of sludge dewatering, and nano material is to the modifying function of traditional amendment simultaneously, thereby further improved the sludge dewatering effect, economize on dose, save drug cost, improve dewatering efficiency.
5, add the high diffusibility of nano material, high penetrating power is diffused in the water-containing sludge medicament of the present invention very soon, and mixes, and speed is fast, nurse one's health modified evenly, dehydrating effect is good.
6, the volume effect of nano material, quantum size effect, chemistry and catalytic, macroscopical tunnel effects etc. have the conditioning performance of urging in matrix material to improve to its influence.
In sum, the present invention is that a kind of neutralising capacity and bridging ability and seepage force are strong, makes the sludge dewatering pretreating effect good, and speed is faster, dosing still less, price is the most flat, the ZShi efficient nano sludge dehydration conditioner of the efficient compound that water ratio is lower.
