Description
Technical field
The present invention relates to technical field of water pollution treatment, prepared by specifically a kind of polypyrrole load volcanic ash compound adsorbent
Method and application.
Background technology
Phosphorus is closely bound up with our life as a kind of very important element.Either in agricultural or industry, phosphorus
It is obtained for and is widely applied, such as fertilizer and detergent.Synthesized newly in addition, the growth and breeding of life entity is also required to substantial amounts of phosphorus
Life necessary material.However, the use of phosphorus generates many problems, when phosphorus is discharged into water environment, serious richness can be caused
Nutrient laden phenomenon.《Urban wastewater treatment firm pollutant emission standard》(GB18918-2002) in one-level emission standard A, the finger of phosphorus
It is designated as total phosphorus 0.5mg/L；Tianjin new landmark《Urban wastewater treatment firm pollutant emission standard》(DB12/599-2015) one-level
Total phosphorus index is reduced to 0.3mg/L as defined in emission standard A.On the other hand, due to《Ten, water》Appearance, nationwide inner city
Town sewage drainage standard proposes mark work and carried out.Country formulates different standards according to different regions, different basins, and water outlet refers to
Mark improves will the China of covering more than half to the area of ground Table IV class water body.And total phosphorus index as defined in ground Table IV water body standard is also
0.3mg/L.Therefore, the inevitable requirement that deep phosphorous removal processing is sewage disposal under the new situation is carried out to sewage disposal plant effluent.
The method for being presently used for phosphorus in water removal has a lot, and absorption method has device simple, and safe operation, cost is cheap,
Effect stability, secondary pollution is small, and adsorbent repeats the advantages that utilizing, therefore has good application prospect and development space.
The active charcoal of currently used adsorbent, mineral-type material, waste agronomic crop material etc., although most of material can be certain
Degree ground Phosphate Sorption, but the absorption property of most natural materials is poor, desorption and regeneration rate is low, and adaptive capacity to environment is poor, it is difficult to
Applied directly as adsorbent.Adsorption effect of activated carbon in water is preferable, but its is costly, it is difficult to realizes industrial big rule
Mould application；Mineral material, such as zeolite, bentonite, montmorillonite, rich reserves are cheap, but natural minerals adsorb
Measure relatively low.Waste agronomic crop material, such as stalk, rice husk, jujube core etc., material is easy to get, cheap, but adsorption capacity is low, and one
As need charcoal burn etc. pre-treatment.
Volcanic ash is earth natural material caused by activity naturally, and cheap in China's rich reserves, it is internal more
Hole, surface hydrophilicity is strong, has good absorption property.Therefore, need a kind of can be prepared using volcanic ash badly and have good suction concurrently
The technology of the compound adsorbent of attached characteristic and electrochemical properties energy.
The content of the invention
The purpose of the present invention is overcome the deficiencies in the prior art, there is provided a kind of high-efficiency and economic, be provided simultaneously with characterization of adsorption and
The polypyrrole load volcanic ash compound adsorbent of electrochemical properties.
