Abstract
The invention relates to a composite phosphorus-accumulating inorganic ferric salt flocculating agent prepared by using waste warm pastes. The material is prepared by the following steps: grinding of used warm pastes, leaching, and reaction. The composite phosphorus-accumulating inorganic ferric salt flocculating agent is used for various waste water treatment. A common material for water treatment is prepared by effectively using waste warm pastes in daily life, so that environmental harm is mitigated, recycling of life waste is realized, and the flocculating agent accords with national policies, such as development of national circular economy, energy saving and emission reduction, and waste utilization.
Description
Technical field
Patent of the present invention belongs to inorganic polymer coagulant preparing technical field, relates to a kind of utilization and discards the warm patch poly-phosphorus inorganic iron saline flocculating agent of preparation compound.
Background technology
The poly-phosphorus inorganic iron saline flocculating agent of compound is Composite Inorganic Polymer Flocculants is exactly wherein important one, and it is a kind of novel inorganic polymer composite flocculant of synthesis on polymer-inorganic ferrum saline flocculating agent basis. Compared with polymer-inorganic ferrum saline flocculating agent, the poly-phosphorus inorganic iron saline flocculating agent of compound to paper-making deinking water, papermaking making beating water, printing and dyeing water coagulating treatment effect can be better than polymer-inorganic ferrum saline flocculating agent.
Warm patch is the hot-sale products in winter now, and its raw material layer is the polymer synthesized by iron powder, Vermiculitum, activated carbon, inorganic salt, water etc., under the effect of oxygen in atmosphere, exothermic reaction can occur. Warm patch is to utilize iron oxidation reaction heat release to generate heat. Actually namely in humid air, there is, according to ferrum, the principle that oxygen uptake corrodes. Utilizing the strong adsorptivity of activated carbon simultaneously, contain steam in the open structure of activated carbon, steam is liquefied as water droplet, flows out and contacts with air and iron powder, and react comparatively rapidly generation hydrated ferric oxide. under the catalytic action of sodium chloride, releases heat. For dark brown solid, wherein carbonaceous powder, sodium chloride, iron sesquioxide 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 in that to utilize a kind of utilization to discard the warm patch poly-phosphorus inorganic iron saline flocculating agent of preparation compound.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of utilization discards the warm patch poly-phosphorus inorganic iron saline flocculating agent of preparation compound, it is characterised in that: discard warm patch and be made up of following material: sodium chloride, activated carbon, iron sesquioxide, Vermiculitum.
A kind of preparation method utilizing the discarded warm patch poly-phosphorus inorganic iron saline flocculating agent of preparation compound told comprises the following steps:
Grinding process: dry at first garbage being placed 100 DEG C, utilizes ball mill to be clayed into power by discarded warm patch granule, and the fineness of powder is at 100 orders. Leaching process: the powder taking a certain amount of mistake 100 order is placed on inside beaker, passes into oxygen and heats, treating complete reaction, adds the HCL solution of appropriate concentration, with certain rotating speed stirring reaction about 4h, filters, obtains pickle liquor. Coagulant preparation process: pickle liquor and disodium hydrogen phosphate mixing and stirring post-heating, controls temperature at 280 DEG C one 320 DEG C, decomposes a period of time, take out and be cooled to room temperature, is sufficiently stirred for into soft solid thing and namely obtains the poly-phosphorus inorganic iron saline flocculating agent of compound.
The present invention effectively utilizes the warm patch of daily life garbage to prepare water and processes common used material, alleviates environmental hazard, it is achieved the renewable resources of domestic refuse, meets national development recycling economy, the national policy that energy-saving and emission-reduction profit is useless.
