Abstract
The invention discloses a papermaking wastewater treating agent, which belongs to the technical field of wastewater treatment. The treating agent is prepared by the steps of adding metal catalyzed ions to attapulgite and then modifying the metal catalyzed ions. The attapulgite is taken as a packing after being modified and is placed in an adsorption tower to adjust the pH value of wastewater to 6.5-7.5, the wastewater passes through the adsorption tower at a flow speed of 10-15 L/min, and the COD (Chemical Oxygen Demand) of effluent can reach an industrial emission standard. The treating agent has the advantages of wide application range, high deposition rate, high effluent quality, low treatment cost, no corrosion effect on a steel structure, no toxicity, no pollution, safe application and the like. The papermaking wastewater treating agent can also be applied to treatment of various wastewater from oil fields, coal mines, textile mills and the like.
Description
Technical field
The invention belongs to technical field of waste water processing, mainly relate to a kind of inorganic agent of paper waste.
Background technology
The vital principle that all things on earth existence is dependent on: water, air, sunlight and magnetic energy, wherein water is most important key element, the place that Ling Quan namely arranged from ancient times always richly endowed by nature, a remarkable place produces outstanding people, everybody long-lived.And now, worker, commercial flourishing epoch society constantly improve, and science and technology is maked rapid progress, and people's standard of living also promotes thereupon, and proper people enjoy the scientific and technological just lance that brings! " simultaneously, what hidden behind but is pollution and the destruction of environment, wherein, in the daily life the most direct impact namely be the problem of water quality severe contamination, to buy the most significantly in recent years the fanaticism of mineral water (mountain spring water), can learn.Obviously, the problem at water source has jeopardized each family really, even with it everyone.
Water treatment agent is not outer to be the effects such as flocculation, scale inhibition, inhibition.Flocculant mostly uses aluminium salt, maximum still aluminium polychlorides.These all belong to the cationic metal type, preferably use simultaneously the flocculant (also claiming flocculant aid) of anionic, and take activated silicic acid as main, activated silicic acid is to make with the diluted acid neutralization with sodium metasilicate.And the multiplex poly-microcosmic salt of antisludging agent, yet its shortcoming be hydrolyzed easily, and to generate not with calcium ion that dissolved salt forms be another kind of dirt.And phosphate is organophosphor preferably, but structure comparatively complexity its cost is improved.And corrosion inhibiter is the novel anticorrosion chemicals that grows up nearly recent decades, and its kind is more, but can be used for domestic water, and is then few especially for drinking water.
Summary of the invention
The present invention be exactly for solve used chemicals treatment weak effect in the existing wastewater treatment, sinking speed is slow, cost is high, the problems such as equipment heavy corrosion, provide a kind of high efficiency, low cost, adaptation wide, without the avirulent paper-making waste water treating agent of burn into.
Technical scheme of the present invention is: described paper-making waste water treating agent is prepared from after the modification through adding the metal catalytic ion by attapulgite again.
A kind of preparation method of inorganic agent of paper waste is:
(1) the attapulgite mechanical disintegration is become the particle of 1.0～1.5mm particle diameter, in the NaOH of 2M, soak 6h,, and in constant temperature (105 ℃) baking oven, dry to neutral with the dilute hydrochloric acid solution washing;
(2) place in the SRJX-2-9 molding box type resistance furnace and carry out thermal activation 3～4h, activation temperature is 800 ℃, is made into 10% metallic iron ion after finishing, and adds 2% metal copper ion;
(3) adopt WF-4000 type microwave flashing reactor, under 120Hz, 90 ℃, add 2% Cetyltrimethylammonium bromide and carry out the modification of concavo-convex microwave organic matter, concavo-convex stand-by after high speed centrifugation, washing, oven dry after the modification.
Application process of the present invention is: attapulgite modified as filler what prepare, place in the adsorption tower, and regulating pH value of waste water is 6.5～7.5, and waste water passes through with 10～15L/min flow velocity, and COD can reach discharge standard in the water outlet.
The present invention has following advantage:
1, the scope of application is wide, and sedimentation effect is good, and effluent quality is good, and processing cost is low; 2, non-corrosiveness; 3, avirulence.
