Abstract

A kind of method of heavy metal ions removal in both culturing microalgae liquid, is related to application process of the related adsorbent in field of microalgae cultivation, and concrete application step is as follows：(1) by the culturing liquid after collection microalgae, first precipitated in sedimentation basin, impurity in culturing liquid is not dissolved in remove；(2) by after culturing liquid filtering after precipitation, filtrate is pumped into the adsorption tank equipped with adsorbent；(3) culturing liquid after adsorbent adsorbs is filtered, filtrate reuses after testing, after adjustment；Beneficial effect is organically combined in by filter material in material for water treatment and food industry etc., is applied in both culturing microalgae industry, so as to reach heavy metal ion in removing culturing liquid, culturing liquid is reused, with cost-effective.

Description

A kind of method of heavy metal ions removal in both culturing microalgae liquid
Technical field
The present invention relates to a kind of method of heavy metal ions removal in both culturing microalgae liquid, particularly phase Close application process of the adsorbent in field of microalgae cultivation.
Background technology
Heavy metal is noxious material, and the method currently used for handling water containing heavy metal ion mainly has Oxidation precipitation, flocculation co-precipitation, absorption and ion exchange, biological prosthetic etc., wherein adsorbing Filter method is daily conventional method because its is inexpensive.Traditional adsorption filtration fado using activated carbon, The adsorbents such as NACF, iron oxide, there is that certain treatment effect is fine, but adsorbent Regeneration cost is high.
In microalga cultivation process, to be cost-effective, culturing liquid will typically be reused, During this, cause the heavy metal ion equal size in water body continuous due to the continuous evaporation of moisture Rise, after several culture-cycles, heavy metal ion content is exceeded, causes culturing liquid can not Use, be unfavorable for the saving of cost.
The method of removing Heavy Metals in Waters ion is the think of based on heavy-metal ion removal at present Carry out, do not consider while heavy metal ions removal, it is impossible to in water body on road Other materials are destroyed.There is substantial amounts of nutrients in the both culturing microalgae liquid of heavy metals exceeding standard Matter, therefore seek a kind of method gesture for neither destroying nutritional ingredient and can removing heavy metal ion and exist It must go.
The cultivation of microalgae belongs to the category of food industry, therefore the application of relevant supplies material is first To consider that it can be used in the food industry.
Diatomite, attapulgite clay, perlite etc. are commonly used in food industry production and do drainage Filter material, there has been no the application in terms of heavy metal ions removal.Its specific surface area is larger, absorption Ability is strong, the processing available for both culturing microalgae liquid.
The content of the invention
It is an object of the invention to had filter material in material for water treatment and food industry etc. Machine combines, and is applied in both culturing microalgae industry, so as to reach heavy metal ion in removing culturing liquid, Culturing liquid is set to reuse, with cost-effective.
The concrete application step of the present invention is as follows：
(1) by the culturing liquid after collection microalgae, first precipitate in sedimentation basin, do not dissolved in removing Impurity in culturing liquid；
(2) by after culturing liquid filtering after precipitation, filtrate is pumped into the absorption equipped with adsorbent Pond；
(3) culturing liquid after adsorbent adsorbs is filtered, filtrate repeats after testing, after adjustment Utilize.
Adsorbent is attapulgite clay, diatomite, perlite, zeolite, manganese dioxide etc..
Adsorbent can be used alone, and can also be used in mixed way.
The flow direction of both culturing microalgae liquid is the high-end entrance from adsorption tank, from the least significant end stream of adsorption tank Go out.
Embodiment
The present invention is further illustrated with specific embodiment below.
Embodiment 1
(1) by the culturing liquid after collection microalgae, first precipitated in sedimentation basin；
(2) by after culturing liquid filtering after precipitation, filtrate is pumped into equipped with attapulgite clay Adsorption tank, it is pumped into from adsorption tank bottom collection solution at the top of adsorption tank, iterative cycles operation, directly It is up to standard to content of beary metal；
(3) culturing liquid after adsorbent adsorbs is filtered, filtrate repeats after testing, after adjustment Utilize.
Embodiment 2
(1) by the culturing liquid after collection microalgae, first precipitated in sedimentation basin；
(2) by after precipitation culturing liquid filtering after, by filtrate be pumped into equipped with attapulgite clay, The adsorption tank of perlite, diatom earth mixtures, adsorption tank is pumped into from adsorption tank bottom collection solution Top, iterative cycles operation, until content of beary metal is up to standard；
(3) culturing liquid after adsorbent adsorbs is filtered, filtrate repeats after testing, after adjustment Utilize.
Embodiment 3
(1) by the culturing liquid after collection microalgae, first precipitated in sedimentation basin；
(2) by after culturing liquid filtering after precipitation, filtrate is pumped into adsorption tank, makes culturing liquid Pass sequentially through equipped with attapulgite clay, perlite, the adsorption tank of zeolite, from last absorption The bottom collection solution in pond is pumped at the top of first adsorption tank, iterative cycles operation, until weight Tenor is up to standard；
(3) culturing liquid after adsorbent adsorbs is filtered, filtrate repeats after testing, after adjustment Utilize.
