Abstract
The invention discloses a process using an inorganic polymer flocculating agent polymerizing aluminum chloride and iron chloride, which is characterized in that, add alkaline matter in acidated waste liquor which is produced in the process that concavo-convex rod stone and clay produce floridin, stir the solution, adjust pH of solution, heat and polymerize solution, then fully stir solution to make reaction, thereby generating an inorganic polymer flocculating agent polymerizing aluminum chloride and iron chloride. The applicable pH range is wider, and the treatment effect is better than other flocculating agent in common usage.
Description
Technical field
The invention belongs to domain of inorganic chemistry, the production method of concrete a kind of inorganic macromolecule flocculant poly aluminium chloride ferrum.
Background technology
Attapulgite clay is meant with attapulgite (Attapulgite) to be a kind of clay mineral of major ingredient.It is the moisture zeopan mineral of a kind of crystalloid, has unique layer chain-like structure feature, has the lattice displacement in its structure, so contain Na+, Ca2+, Fe3+, the Al of non-quantitative in the crystal, crystal is needle-like, fibrous or fibrous agrregate.Attapulgite has unique dispersion, high temperature resistant, anti-good colloidal property such as saline and alkaline and higher adsorption bleaching ability and certain plasticity-and cohesive force, and the intermediate structure between chain-like structure and laminate structure.Utilize attapulgite clay to produce atlapulgite, belong to natural oil product decolouring sorbent material.Be mainly used in edible oil (animal and vegetable oil), industry oil, waste oil regeneration (black diesel oil, used oil) product decolouring and refining catalysis, absorption, the carrier etc. of reaching.In process of production, produce a large amount of acidifying waste liquids, at present industrialized utilization not as yet.
Summary of the invention
The production method that the purpose of this invention is to provide a kind of inorganic macromolecule flocculant poly aluminium chloride ferrum, producing the acidifying waste liquid that produces in the process of atlapulgite with attapulgite clay is raw material, in addition concentrated base neutralization is produced and is obtained aluminium iron polychloride floculant, turns waste into wealth.Technical scheme of the present invention is as follows:
A kind of production method of inorganic macromolecule flocculant poly aluminium chloride ferrum, it is characterized in that producing in the acidifying waste liquid that produces in the process of atlapulgite at attapulgite clay, by adding alkaline matter, stir, the adjustment pH value of solution is 3.8-4.2, is heated to 80～90 ℃, abundant again stirring reaction 4～5 hours, make its polymerization, generate inorganic macromolecule flocculant poly aluminium chloride ferrum liquid product, this liquid product is the solid polyaluminium chloride iron product after slaking drying under the certain condition.
The production method of described inorganic macromolecule flocculant poly aluminium chloride ferrum is characterized in that the acidifying waste liquid is meant the acidifying waste liquid that produces in the process of attapulgite clay production atlapulgite.
