Abstract

The invention relates to aggregated inorganic iron flocculant prepared from abandoned warm paste. The material is prepared from warm paste used and sodium silicate according to mass parts. Particles are prepared through grinding, soaking and reacting. The prepared aggregated inorganic iron flocculant can be used for processing various types of wastewater. Material frequently used for water processing are effectively prepared from daily life abandoned warm paste, environment damage is reduced, life waste is recycled, and the aggregated inorganic iron flocculant conforms to the national strategy of national development circular economy, energy conservation, emission reduction and waste utilization.

Description

Polymer-inorganic iron-based flocculating agent is prepared in the discarded warm subsides of a kind of utilization
Technical field
Patent of the present invention belongs to inorganic polymer coagulant preparing technical field, relates to the discarded warm subsides of a kind of utilization and prepares polymer-inorganic iron-based flocculating agent.
Background technology
Polymer-inorganic iron-based flocculating agent is a class inorganic polymer flocculant, it metal ion is incorporated into polymer inorganic and obtained composite flocculant. it is good that it has flocculating effect, floc settling velocity is fast, steady time is long, raw material sources are wide, low price, the advantages such as the residue after process in water is few.
Warm subsides are the hot-sale products in winter now, and its raw material layer is the polymkeric substance synthesized by iron powder, vermiculite, gac, inorganic salt, water etc., under the effect that can be oxidized in atmosphere, thermopositive reaction occurs.Warm subsides utilize iron oxidation reaction heat release to generate heat.In fact in damp atmosphere, the principle of oxygen uptake corrosion is namely there is according to iron.Utilize the strong adsorptivity of gac, in the short texture of gac, contain water vapour, water vapour is liquefied as water droplet simultaneously, and flow out and contact with iron powder with air, react comparatively rapidly generation ironic hydroxide under the katalysis of sodium-chlor, releases heat.Be dark brown solid, wherein carbonaceous powder, solid sodium chloride, ferric oxide solid and the salt containing magnalium after using.
Summary of the invention
The present invention relates to a kind of inorganic polymer coagulant, specific purposes are to utilize the discarded warm subsides of a kind of utilization to prepare polymer-inorganic iron-based flocculating agent.
To achieve these goals, the technical solution used in the present invention is as follows:
Polymer-inorganic iron-based flocculating agent is prepared in the discarded warm subsides of a kind of utilization, it is characterized in that: waste is made up of following material: sodium-chlor, gac, ferric oxide, vermiculite.
A kind of preparation method utilizing discarded warm subsides to prepare polymer-inorganic iron-based flocculating agent told comprises the following steps:
Grinding process: dry at first waste being placed 100 DEG C, utilize ball mill to be clayed into power by the discarded warm particle that pastes, the fineness of powder is at 100 orders.Leaching process: get a certain amount of mistake 100 object powder and be placed on inside beaker, add the sulphuric acid soln of appropriate concentration, heat up and pass into oxygen and stir, then heating in water bath, treats complete reaction, cooling, filters.Coagulating agent preparation process: take a certain amount of water glass, adds water and makes it to dissolve, be made into sodium silicate solution, regulate certain pH value with sulfuric acid, at room temperature activate certain hour, then add the ferrum sulfuricum oxydatum solutum prepared by Waste iron slag, ageing for some time, obtain polymer-inorganic iron-based flocculating agent.
Advantage of the present invention:
The present invention effectively utilizes warm subsides of daily life waste to prepare water treatment common used material, alleviates environmental hazard, realizes the renewable resources of domestic refuse, meet national development recycling economy, the national policy that energy-saving and emission-reduction profit is useless.
