Abstract
The invention discloses a method for removing gallium in sewage, and belongs to the field of sewage treatment in environment protection. Aluminium polychlorid and polyacrylamide are added to wastewater containing gallium; the wastewater containing gallium enters a magnetic suspension reactor through a pipeline reactor to generate flocculation micelles under the effect of electrolysis; the precipitated flocculation micelles are rinsed by a wash pipe; the aggregate mixture forms a loose state; the floc is separated from magnetic powder under the effect of a magnetic field; and the separated magnetic powder is fed to an electrolytic cell to recover, and the sludge is discharged into a sludge pipe. The method has the characteristics that the method is simple in technologic process, simple to operate, low in operating expense, free of sludge, high in gallium removal rate and the like; and the concentration of the residual gallium ion in the water after primary treatment is lower than 1.25mg/L and lower than the first grade discharge standard in state regulations.
Description
Technical field
The present invention relates to a kind of method of removing gallium in the sewage, particularly process the waste water of gallium concentration in 10～100mg/L scope, belong to field of waste water treatment in the environment protection.
Background technology
Heavy metal wastewater thereby is different according to element kind, content and the form that exists in solution, can adopt diverse ways to process.Treatment process commonly used has: chemical method, physico-chemical processes, biochemical process, electrochemical process, flotation process, membrane technology and microwave technology etc., because chemical precipitation method must cause precipitated product solubleness in system to increase when gallium ion concentration was higher, caused the heavy metal content in the processed waste water to exceed standard; Under strong acid condition, no matter physisorphtion adopts the sorbent materials such as gac, zeolite, all can greatly reduce adsorption effect; Biological treatment is better for the treatment effect of conventional heavy metal ion, then is the obstacle that is difficult to go beyond but cultivate the bacterial classification that is fit under the high gallium condition; Although membrane processing method is to the processing comparative maturity of heavy metal ion, when gallium ion concentration raises, the damage of film and replacing will become restricted link.For the variety of issue that exists in the existing heavy metal waste water treatment process, it is particularly important to develop a kind of new processing method.
Summary of the invention
The objective of the invention is provides a kind of method of removing gallium in the sewage for overcoming the deficiencies in the prior art, and this invented technology flow process is simple, running cost is low, obvious processing effect, residual gallium ion concentration is lower than 1.25mg/L in the water after primary treatment, is lower than the first discharge standard of national regulation; Produce without precipitation, can not cause secondary pollution, and the equal recoverable of the metal oxide in water outlet and the waste water.
Concrete treatment step of the present invention is:
(1) adds the polymerize aluminum chloride of 120～150ppm and the polyacrylamide of 3～5ppm, flocculating settling in flocculation basin in the gallium waste water to containing;
(2) the gallium waste water that contains of removal suspended particulate enters into the magnetic levitation reactor through pipeline reactor;
(3) add electrolyzer simultaneously in reactor, electrode is iron and aluminium alloy, the energising electrolysis;
(4) under the effect of electrolysis, produce the flocculation micelle, by the magnetic levitation separating device micelle is purified, the water after the processing enters clean water basin;
(5) the flocculation micelle after the precipitation washes away with wash pipe, and the flco mixture is loose condition (of surface), and under the effect in magnetic field, flco separates with magnetic;
(6) will separate after magnetic be sent to electrolyzer and reclaimed, mud is drained into sludge pipe and gets final product.
Application method of the present invention is: add polymerize aluminum chloride and polyacrylamide in the gallium waste water to containing; Contain gallium waste water and enter into the magnetic levitation reactor through pipeline reactor; Under the effect of electrolysis, produce the flocculation micelle; Flocculation micelle after the precipitation washes away with wash pipe, and the flco mixture is loose condition (of surface), and under the effect in magnetic field, flco separates with magnetic; Magnetic is sent to electrolyzer and is reclaimed after will separating, and mud is drained into sludge pipe and gets final product.
The invention has the beneficial effects as follows: it is simple that the present invention has technical process, simple to operate, and working cost is lower, without sludge creation, except gallium effect high, residual gallium ion concentration is lower than 1.25mg/L in the water after primary treatment, is lower than the first discharge standard of national regulation.
