Abstract
The invention relates to a polymerized 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 polymerized 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 the discarded warm patch of a kind of utilization and prepares polymeric iron saline flocculating agent.
Background technology
Ferrum saline flocculating agent produces polymeric iron saline flocculating agent by polymerizing cationically, plays charging neutrality and bridge flocculation effect, and compared with common flocculant, it is fast that floccule body forms speed, and granule is closely knit, and ratio is great, and sedimentation velocity is fast; Good removal effect is all had for the COD in various waste water, BOD, colourity and heavy metal; Floccule body is strong with the binding ability of microorganism, thus the microorganisms such as plankton are had good removal effect.
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, solid sodium chloride, iron sesquioxide 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 in that to utilize the discarded warm patch of a kind of utilization to prepare polymeric iron saline flocculating agent.
To achieve these goals, the technical solution used in the present invention is as follows:
The discarded warm patch of a kind of utilization prepares polymeric iron saline flocculating agent, it is characterised in that: garbage is made up of following material: sodium chloride, activated carbon, iron sesquioxide, Vermiculitum.
A kind of preparation method utilizing discarded warm patch to prepare polymeric iron saline flocculating agent 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, adds the H of appropriate concentration2SO4Solution, with certain rotating speed stirring reaction about 4h, filters, obtains pickle liquor. Coagulant preparation process: pickle liquor passes into oxygen and stirs, and treats complete reaction, obtains polymeric iron saline flocculating agent.
The advantage of the present invention:
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.
