Description

Composite flocculation agent
Technical field
The present invention relates to technical field of sewage, and in particular to a kind of inorganic-organic flocculant and preparation method thereof.
Background technology
Polyacrylamide is a kind of important high polymer coagulant, has stronger flocculation ability, is widely used in sewage Process field, such as textile waste, dyeing waste water, paper waste, mud waste water, mining wastewater, waste-water from coal mine, municipal wastewater, electricity Waste electroplating, wastewater from chemical industry, breeding wastewater, oil industry wastewater, leather waste water, food wastewater, Wastewater From The Beverage Industry, alcohol waste water, steel The every profession and trades such as iron waste water, pharmacy waste water, non-ferrous metals industry waste water.
In existing wastewater treatment industry, the polyacrylamide of single variety is usually used as flocculant, it is single The polyacrylamide flocculant of kind has the following defects:(1)Flocculating effect is unstable;When the sewage composition of manufacturing enterprise occurs When variation, single polyacrylamide flocculating effect can have a greatly reduced quality.Furthermore the materialization mud of most of producer and biochemical mud do not have Separately processing, usually mixes and presses mud together;Sewage treatment plant receives all kinds of waste water, and the sludge of generation also can not single pressure mud.Cause This, the polyacrylamide of single variety cannot be satisfied the market demand.(2)Flocculating effect is easy by water quality impact;Polyacrylamide The water quality situation of dissolving water has apparent influence to its flocculating effect.In remote districts, water mineral content is high, to cation The molecular structure of polyacrylamide has certain brokenization effect.Northern area water temperature in winter is low, and product dissolution time is slow.(3)It is viscous Degree is high;Existing medicine machine is when dissolving polyacrylamide, overlong time, since the viscosity of polyacrylamide is high, equipment pipe Road is easy to block.In addition, south is easy to block because air humidity is big, at dosing funnel.(4)Cost depletions are high;Worker is in dosing When, loss is inevitably will produce, the polyacrylamide of high-purity can cause enterprise's cost depletions to increase.Meanwhile also increasing The unstability factor at scene, polyacrylamide become scattered about ground as cleared up not in time, hygroscopic tacky, and personnel is caused to fall .
Invention content
Technical problem to be solved by the invention is to provide a kind of composite flocculation agents, it can solve single in the prior art The problem that Flocculating Effect of Flocculant is unstable, dissolution time is long, dosage is big, of high cost, for this purpose, the present invention also provides one kind again Close the preparation method of flocculant.
To solve the above-mentioned problems, the present invention uses following technical scheme:
The first aspect of the present invention provides a kind of composite flocculation agent, including following components:The cation polypropylene of different ions degree Amide, inorganic salts, organic acid and antifoaming agent, the cationic polyacrylamide of the different ions degree are 10%-80% by ion degree Cationic polyamide composition.
Further, include each component of following parts by weight:The cationic polyacrylamide 20-80 of different ions degree Part, 10-80 parts of inorganic salts, 1-10 parts of organic acid, 1-10 parts of antifoaming agent.
Preferably, include each component of following parts by weight:Ion degree be 10% 10 parts of cationic polyacrylamide, ion Degree is 80% 10 parts of cationic polyacrylamide, 70 parts of inorganic salts, 10 parts of organic acid, 10 parts of antifoaming agent.
Preferably, include each component of following parts by weight:Ion degree be 30% 25 parts of cationic polyacrylamide, ion Degree is 70% 25 parts of cationic polyacrylamide, 45 parts of inorganic salts, 3 parts of organic acid, 2 parts of antifoaming agent.
Preferably, include each component of following parts by weight:Ion degree be 40% 50 parts of cationic polyacrylamide, ion Degree is 60% 30 parts of cationic polyacrylamide, 18 parts of inorganic salts, 1 part of organic acid, 1 part of antifoaming agent.
Preferably, include each component of following parts by weight:Ion degree be 50% 20 parts of cationic polyacrylamide, ion Degree is 80% 60 parts of cationic polyacrylamide, 10 parts of inorganic salts, 5 parts of organic acid, 5 parts of antifoaming agent.
Preferably, the inorganic salts are one or more in sodium chloride, sodium sulphate, ammonium chloride.
Preferably, the organic acid is citric acid or sulfamic acid.
Preferably, the antifoaming agent is organic silicon antifoaming agent, polyether antifoam agent, mineral oil defoaming agent, aliphatic alcohols One kind in antifoaming agent.
The composite flocculation agent of the present invention, is used cooperatively, different ions using the cationic polyacrylamide of different ions degree Synergistic function is generated between the cationic polyacrylamide of degree, improves flocculating effect, reduces the dosage of medicament, is improved The applicability of product, considerably reduces production cost.
Inorganic salts in the present invention can balance electrolyte in water, shorten the dissolution time of polyacrylamide, meanwhile, it is inorganic Salt can inhibit the breeding of microorganism in water, have certain bactericidal effect.
Organic acid in the present invention can inhibit the degradation of cationic polyacrylamide, improve cationic polyacrylamide Flocculating effect is obtained through experiment, and in the high water of content of mineral substances, organic acid, which is added, can obviously inhibit the drop of polyacrylamide Solution.
Antifoaming agent in the present invention has defoaming effect.Foam in the gentle mud scum of usual anaerobism mud is more, antifoaming agent energy Enough surface tension for effectively reducing bubble, reduce bubble amt.In follow-up sludge dewatering link, it is aqueous can effectively to reduce sludge Rate reduces sludge yield, and Treatment of Sludge cost is reduced for enterprise.
The second aspect of the present invention provides a kind of preparation method of composite flocculation agent, is used to prepare above-mentioned composite flocculation Agent includes the following steps:Transit mixer is added in the cationic polyacrylamide of different ions degree, in proportion into blender Inorganic salts, organic acid and antifoaming agent are sequentially added, starts transit mixer, material is uniformly mixed, finished product.
There is in the composite flocculation agent of the present invention between the cationic polyacrylamide of different ions degree synergistic effect, be easy to Dissolving, to changing the sewage flocculation effect stability of property, dosage is small, at low cost, can be widely applied for municipal wastewater, all kinds of works The processing of industry sewage, with good economic efficiency and social benefit.
