Embodiment Construction

[0029] As shown in Figure 1, a one-step synthesis method is adopted, and different industrial waste residues (material 1, material 2, and material 3) are used as main agents to control SO 4 2- / Fe (molar ratio) 1.3 ~ 1.6, to prepare polyaluminum ferric sulfate with different basicity. During the process, the measured fly ash is added as an auxiliary agent. On the one hand, it is used as an insoluble suspending agent to make the polymer stable and easy to separate; on the other hand, it provides the aluminum ions required by the polymer to obtain the product.

Abstract

This invention relates to production of aggregate aluminium sulphate iron. Industrial waste residue used as raw material, flying ash as auxiliary agent, a one-step synthesizing method achieves to yield the macromolecule flocculant. The macromolecule flocculant has the characteristic of aluminium salt and iron salt flocculant. And it can cleanse water and many other uses, specially, good for environment.

Description

technical field [0001] The invention relates to a production process of an inorganic polymer flocculant, in particular to a production process for synthesizing an inorganic polymer flocculant polyaluminum ferric sulfate by using industrial waste slag as a main agent and fly ash as an auxiliary agent. It belongs to the field of international patent classification CO1F7 / 76 "sulfate double salt". Background technique [0002] Aluminum and iron polymer inorganic polymer water purifiers are a new type of chemical industry researched and developed from the 1970s to the 1990s. As water purifiers, they have played a great role in improving people's quality of life and improving the environment. . At present, the industrial waste residue from the sulfuric acid production plant is discharged randomly, causing environmental pollution, which urgently needs to be treated. After retrieval, Chinese patent CN1219507 discloses a "one-step production process of polymerized ferric sulfate so...
