Description

A kind of preparation method of slow release nickel element biological ceramic particle
Technical field
The preparation method that the present invention relates to the magnesia haydite of a kind of baking-free type, the preparation method particularly relating to a kind of slow release nickel element biological ceramic particle.The haydite prepared by the present invention is applicable to lack the organic wastewater anaerobic bio-treated of micro-nickel metallic element.
Background technology
In anaerobic waste water biological treatment process, microorganism is only small to the requirement of minor metallic element, but owing to minor metallic element take part in the composition of enzyme, is the indispensable part of synthesized micro-organism cell.If nickel is coenzyme, hydrogenase, methane backeria F430With the component of carbon monoxide dehydrogenase, the growth of promotion methanogen and the formation of methane.The shortage of micro-nickel metallic element can cause that biological activity reduces, and then affects operational effect and the stability of whole bioreactor.Directly add nickel salt and can be supplied to the minor metallic element that microorganism is necessary, but the precipitation of hydroxyl in water and colloid and complexing can reduce its bioavaliability, excessive add, water body can be produced heavy metal pollution.Exempting from steam curing baking-free ceramicite is in the adsorbent loading in haydite by nickel metal ion, make its slow releasing trace metal ion, increase the bioavaliability of micro-nickel metallic element, improve the treatment effeciency of organic wastewater microorganism, reduce and too much put into potential Heavy-metal Polluted Environment risk produced by nickel metal ion.This biological ceramic particle cost of manufacture is relatively low, it is easy to industrialized production, is the treatment effeciency improving organic wastewater anaerobe, it is to avoid directly add the excellent technique of nickel metal ion pollution water body.
Summary of the invention
The purpose of the present invention, the preparation method being to provide a kind of slow release nickel element biological ceramic particle, technique is simple, and cost is low, is particularly suitable for lacking the anaerobic bio-treated of the organic wastewater of nickel element, can be effectively improved waste water COD clearance.
The technical scheme is that
A kind of preparation method of slow release nickel element biological ceramic particle, it is with magnesium oxide, magnesium chloride, flyash for major gelled material, with Vermiculitum for carrying the carrier of trace Ni element, phosphoric acid is as the modifying agent of gel rubber material resistance to water, KCl is haydite pore former, after unburned technique maintenance at normal temperatures 4 days, to obtain final product；Specifically include following step:
1, Vermiculitum is dried 12 hours at 105-110 DEG C, with the screening of 8-30 target quasi-sub-sieve, dry, take the Vermiculitum after drying that sieves and put into the nickel chloride solution of 1-2mol/L soaks and pull out standby in 5 hours；
2, flyash is dried to constant weight at 105 DEG C, pulverize with Universalpulverizer, standby with the screening of 300-400 mesh sieve；
3, according to flyash, MgO, MgCl2, KCl, Vermiculitum, phosphoric acid mass ratio be 45-50:14-20:12-17:11-15:5-9:0.5-3 feeding, and by flyash, MgO, MgCl2、H3PO4, KCl adds in container and stirs; add through step 1 process Vermiculitum (drying sieve after Vermiculitum be 5-9 with other component ratio;) stir; it is slowly added dropwise water more not stop to stir; until pulverous raw material starts retrogradation; put into comminutor extruded, seal natural curing 4 days, prepare the biological ceramic particle of slow release trace meter nickel element.
It is an advantage of the current invention that:
1, the biological ceramic particle that natural curing method is prepared for a kind of slow release nickel element is adopted to save the energy；
2, this biological ceramic particle preparation method is relatively simple, and this biological ceramic particle can slow release micro-nickel metallic element, it is adaptable to lack micro-nickel metallic element organic wastewater anaerobic bio-treated, it is possible to improve waste water COD clearance, increases methane factor of created gase.
3, with a process for preparing the slow release haydite process waste water with release micro-nickel metal ion, its raw material is easy to get, and convenient cheap, production cost is low, has certain market value.
