Description
Technical field
The present invention relates to calcium silicate board reutilization technology fields, especially a kind of to prepare sewage using calcium silicate board leftover pieces
The method of inorganic agent.
Background technique
Calcium silicate board is using the loose staple fiber such as inorganic mineral fiber or cellulose fibre as reinforcing material, with siliceous-calcium
Cementing material based on material through slurrying, molding, accelerates curing reaction in high temperature and high pressure saturated steam, forms calcium silicates
Gel and manufactured plate.Calcium silicate board is most advanced one of chamber materials for wall at present, has waterproof, moisture-proof.It is resistance to
Long, the advantages that deformation rate is low, heat-insulated is particularly suitable as the wallboard and ceiling board of building interior.
The production process of calcium silicate board includes slurrying, molding, steam-cured, drying, sanding and chamfering, sanding therein
Preferable leftover bits can be generated with chamfering, and how to be preferably a problem to be solved using these leftover bits.
Summary of the invention
The present invention provides a kind of method for preparing sewage-treating agent using calcium silicate board leftover pieces, by by calcium silicate board
Leftover pieces be modified, make it have higher wastewater treatment efficiency.
To achieve the above object, the technical solution of the present invention is as follows:
A method of sewage-treating agent is prepared using calcium silicate board leftover pieces, comprising the following steps:
S1. calcium silicate board leftover pieces are crushed to 30 ~ 50 mesh, obtain calcium silicate board powder；
S2. polyacrylamide is dissolved in water, be adjusted to concentration be 0.1 ~ 0.8% solution, then by calcium silicate board powder be added to
In polyacrylamide solution, liquid-solid ratio is 10 ~ 50g/L, and 2 ~ 3h is mixed, and is placed in 6 ~ 10h of storage in 2 ~ 4 DEG C of environment,
Filtering, filtered powder freeze-drying, obtains sewage-treating agent.
Preferably, in the step S2, mixing speed is 50 ~ 100r/min.
Preferably, in the step S2, the vacuum degree of freeze-drying is set as 20 ~ 30Pa, temperature is -20 ~ -10 DEG C, does
The dry time is 15 ~ 25h.
Preferably, in the step S2, the concentration of polyacrylamide solution is 0.7%, liquid-solid ratio 45g/L.
The above-described method for preparing sewage-treating agent using calcium silicate board leftover pieces, by the way that calcium silicates is carried out powder
It is broken, it adds polyacrylamide solution and carries out low temperature reunion, form the sewage-treating agent with good flocculation and adsorption effect, energy
Preferable absorption heavy metal, while phosphorus and COD content are reduced, it is effective refuse reclamation to calcium silicate board leftover pieces.
