Description
Technical field
The present invention relates to technical field of sewage, especially a kind of heavy metal-polluted water administering method.
Background technology
Heavy metal wastewater thereby is from departments such as metallurgy, plating, mining, chemical industry, such as mine drainage, waste-rock yard leaching immersion, choosing
The tailing draining of ore deposit factory, non-ferrous metals smelting works' draining, Non-ferrous Metals Processing Factory's acid washing water, Electroplate Factory's plating piece washings, steel plant
Pickling draining, and the waste water of the industry such as electrolysis, pesticide, medicine, paint, pigment.Species, the content of heavy metal ions in wastewater
It is widely different and its existing forms are different with different production species.As exploitation of the mankind to heavy metal, smelting, processing etc. are raw
Production activity it is increasing, the heavy metal wastewater thereby of generation whether all greatly increases in quantity or from species, causes
Many heavy metals enter the water bodys such as lake, river, cause the serious heavy metal pollution of water body.Therefore, heavy metal-polluted water
Administer the key subjects of always field of environment protection.It is more to the administering method of heavy metal-polluted water at present, but all there is processing
Of high cost, the problem of efficiency is low.
Caragana microphylla is used as most extensive reliable vanguard tree seed, has the characteristics that drought resisting, resistance to lean, resistance and sprouting ability are strong,
Can and its dead soil in grow, check winds and fix drifting sand, sent out during water and soil conservation in northern China arid, semiarid zone
Wave very important effect.According to statistics, there is 6,700,000 hectares of caragana microphylla woods area in China at present, and the utilization of caragana microphylla resource mainly collects
In in the energy, production feed, as raw material of industry manufacture glued board etc., but due to by cost of material, product price etc. it is a variety of because
The influence of element, the utilization rate of the current caragana microphylla resource in China are less than 40%.Therefore, many caragana microphylla woodss are also in uncultivated state, by
In not managed timely and stump, there is plant senesecence, it is slow-growing, in turn result in that ecological functions are low etc. to ask
Topic.Therefore, the efficient utilization ways of caragana microphylla resource are explored and then promote northern China ecological construction more preferably development to become research
Important content.
The content of the invention
The technical problem to be solved in the present invention is：Present invention proposition one kind is raw material using caragana microphylla, prepares novel adsorption

Warm speed is 10~20 DEG C/min, and the constant temperature time that set temperature is 500~700 DEG C is 2~3h, is cooled to room temperature, obtains afterwards
To caragana microphylla charcoal；
(4) caragana microphylla charcoal is immersed in the hydrogenperoxide steam generator that mass concentration is 1~3%, in 50~80 DEG C of conditions of temperature
When lower stirring, immersion 1~3 are small, then filter, wash to neutrality；
(5) the caragana microphylla charcoal after washing is immersed in the hydrochloric acid of concentration 1mol/L, soaks 2 under the conditions of 50~80 DEG C of temperature
~4 it is small when, then filter, wash to neutrality；
(6) caragana microphylla charcoal is immersed in the aluminum sulfate solution of mass concentration 10~40%, is stirred under the conditions of 30~60 DEG C
30 minutes；
(7) the filtering of caragana microphylla charcoal, the drying of step (6)；
(8) the caragana microphylla charcoal after drying, anaerobic cracks 30~60 minutes under the conditions of 500~700 DEG C；
(9) the caragana microphylla charcoal ethanol after cracking and distillation water washing；
(10) the caragana microphylla charcoal after washing under the conditions of 60~80 DEG C of temperature drying, cross 60~80 mesh sieves, obtain modified lemon
Bar carbon；
(11) bed mud of heavy metal-polluted water is taken, through being dehydrated, drying, crushing, crosses 60~80 mesh sieves；
(12) the bed mud after screening and modified caragana microphylla carbon by volume 1:3 ratio mixing, obtains new adsorbent；
(13) the uniform cloth of new adsorbent is spread in heavy metal-polluted water；
(14) Sediments are excavated in the dry season, a part of bed mud gives over to making new adsorbent, most of bed mud fortune
Filled toward landfill yard.
It is raw material the beneficial effects of the invention are as follows the bed mud using caragana microphylla and heavy metal-polluted water, prepares novel adsorption
Agent, the new adsorbent have good absorption, exchange and settling property to heavy metal ion, can be right using the new adsorbent
