Abstract
The invention discloses an arsenic-removing composite material for drinking water. The material comprises the following components by weight: 45 to 50 parts of ultrafine polyethylene resin, 35 to 45 parts of powdered activated carbon, 15 to 20 parts of sodium chloride and 3 to 5 parts of ferric nitrate. The material provided by the invention has the advantages of good arsenic-removing capacity and mechanical strength, stable flow rate in an application and operation stage, no introduction of obvious foreign matters into treated water, and significant improvement of water turbidity and oxygen consumption index.
Description
Technical field
The present invention relates to field of compound material, particularly relate to a kind of Arsenic Removal from Drinking Water matrix material.
Background technology
The traditional method of Arsenic Removal from Drinking Water has coagulant sedimentation, absorption method and ion exchange method etc., these methods or need accurately to control dosage, and introduces too much foreign matter in process water, or complicated operation, should not promote the use of, or large by water quality impact, arsenic removal capacity is limited.
Summary of the invention
The object of the invention is to the above problem overcoming prior art existence, a kind of Arsenic Removal from Drinking Water matrix material is provided, meets the primary demand in market.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of Arsenic Removal from Drinking Water matrix material, counts by weight, comprises the micronized polyethylene resin of 45 ~ 50 parts, the Powdered Activated Carbon of 35 ~ 45 parts, the sodium-chlor of 15 ~ 20 parts, the iron nitrate of 3 ~ 5 parts.
Further, fully infiltrate with ionized water before described Powdered Activated Carbon and iron nitrate use, and in 120 DEG C of bakings 12 hours after water bath method, sieve.
Further, described composite material and preparation method thereof comprises the following steps: after described micronized polyethylene resin, Powdered Activated Carbon, sodium-chlor, iron nitrate being mixed in proportion, hot-forming, washing pore-forming.
Further, also comprise a certain proportion of pore former of mixing in described step, and comprise resol in described pore former.
Further, the blending ratio of described micronized polyethylene resin and iron nitrate is 50:35.
The invention has the beneficial effects as follows:
Material of the present invention has good arsenic removal capacity and physical strength, uses operation phase stability of flow, introduces, have clear improvement simultaneously to water turbidity and oxygen-consumption index to water quality after process without obvious foreign matter.
Embodiment
Below in conjunction with embodiment, describe the present invention in detail.
