Description
Technical field
The present invention relates to saprobia and administer the field, be specifically related to a kind of utilize the solidified algae ball dispose of sewage in the method for organo-tin compound.
Background technology
Organo-tin compound is widely used in PVC stabilizer for plastics, various Insecticides (tech) ﹠ Herbicides (tech), textiles mould inhibitor and marine vessel antifouling paint etc. in industrial or agricultural.The tributyl tin (TBT) and the triphenyltin (TPT) that wherein are used for ship antifouling paint and sterilant are to introduce one of the most malicious chemical substance of water surrounding by human activity up to now, be confirmed to be environment incretion interferent (causing that the gastropod sex distortion is one of organotin internal secretion interference effect) at present, simultaneously, also there is the biological accumulation effect in the organotin pollution thing, and ecotope is had serious harm.
Though International Navigation Transportation Organization (IMO) passes a resolution recently, requirement is forbidden being coated with the paint that contains tributyl tin organic tin compounds such as (TBT) at boats and ships from January 1st, 2003 in the world, but because the extended residual of organotin in ocean environment, even after stopping using the long duration, still can exist in seawater and the bed mud.Root report by the coastal and geographic sampling determination of inner waters to China, finds that sampling point exists the pollution condition of organotin bar none, and the sea-food that gather in 7 cities of China measured, and all found the existence of TBT etc.China's organotin year usage quantity up to 7500t, the TBT pollution survey result of indivedual harbours of China and inner waters is shown that there is more serious organotin pollution in China.And by investigation to water supply plant in some city, the China north, bibliographical information is arranged, traditional handling technology of water supply can effectively be removed monobutyl tin (MBT) and dibutyl tin (DBT), but organo-tin compounds such as TBT and MPT are not but had removal effect substantially.
At present, in the water body there be the conversion main path of organotin pollution thing:
1. chemical degradation: although the Sn-C key under acid, alkali and oxygenant effect, exist fracture may because the concentration in environment is extremely low, it is very slow to degrade, organotin is quite stable in air, more is difficult for oxidized.
2. photodegradation: the Average bond energy of organo-tin compound Sn-C key is 190-220kJ/mol, and maximum molecular absorption is arranged in the UV district of 290nm.(CH) energy of Sn generation photolysis needs is 370ld/mol.The existing many reports of the photochemical reaction of organotin under envrionment conditions.Comprehensive a lot of achievement in research, its reaction mechanism is the process of sloughing alkyl continuously, final product is an inorganic tin.Result of study shows that under solar light irradiation, TBT in water photolysis can take place, but photodissociation speed is slow especially.
3. biological degradation: biological degradation transforms particularly important to the organotin in the environment.It is generally acknowledged that biological and microbiological deterioration is the topmost approach of organotin degraded in the water.Microalgae (Chlorella vulgaris and Chlorella sp.) to organotin particularly TBT very strong tolerance is arranged.By these two kinds of microalgae cell outer surfaces and intracellular TBT are distributed, and the mensuration of degraded product dibutyl tin (DBT) and monobutyl tin (MBT), the result shows: dibutyl tin (DBT) just occurred in first day in developing medium, for two kinds of chlorella biological degradation TBT provide foundation.Alga cells wall bio-absorbable TBT can reach 40% in initial 2 days.Subsequently, the TBT that is adsorbed on the cell walls just can be degraded in the cell of little algae.
But, when little algae is used in organo-tin compound in purifying treatment sewage, tap water, the natural water body, the problem of the maximum that is run into is exactly to isolate the microalgae cell that cell dia is approximately 2-5 μ m from treated sewage, make it can successive remove organo-tin compound in the sewage, improve processing efficiency, reduce processing cost etc.So, how science, effectively utilize little algae to handle the waste water that contains organic tin pollution thing, become the hot issue of academia's research.
Summary of the invention
The objective of the invention is to overcome little algae and handle and exist little algae to be difficult to reclaim in the organotin pollution thing, can not processed continuously problem, a kind of method of utilizing little algae can continuous in-situ to handle the organotin pollution thing is provided.
To achieve these goals, the present invention adopts following technical scheme: the present invention utilizes can the degrade character of organo-tin compound of little algae, by little algae is made into the algae ball, the algae ball places the open container of micropore, printing opacity, the mesh diameter of container is less than the algae spherical diameter, so the algae ball can not ooze out netted open container.The container that the algae ball will be housed then places sewage, and the container upper end opening exposes oilysewage surface, is taken away by current to prevent the solidified algae ball, and staying water enters and contacts with the solidified algae ball of inside from the micropore of vessel surface.Organo-tin compound in the water just can be adsorbed on the algae ball and by frustule and decompose.
The method that above-mentioned little algae is made into the algae ball is: will concentrate frustule suspension and mix with solution of sodium alginate, and form algae-alginate mixed solution; This algae-alginate mixed solution is pumped in the gel-based solution of calcium chloride and sodium-chlor, form the algae ball.
Above-mentioned little algae is preferably Chlorella vulgaris and Chlorella sp.
Compared with prior art, the present invention has following beneficial effect: the present invention by little algae immobilization technology is adsorbed with little algae, biodegradation technique combines, and microorganism is fixed in the algae ball, prevents that the algae ball from flowing along with water body and lose.It can be recycled, improve processing efficiency and reduced processing cost.In addition, little algae is fixed on after the algae ball, still can normal growth, breeding, and also the little algae after fixing strengthens to some extent for the tolerance and the degradation efficiency of organo-tin compound.Because organo-tin compound is earlier adsorbed by algae ball surface, and then fallen the indirect like this concentration that has reduced little algae contact stain thing by little algae metabolism.Can be used for administering seriously polluted zones such as the harbour stretch of coastal water, river, pond.
Description of drawings
Fig. 1 is solidified algae ball decontamination apparatus figure;
Wherein, 1 is the open container of micropore, printing opacity, and 2 is micropore, and 3 is the algae ball.
Embodiment
The preparation of solidified algae ball: will concentrate frustule (Chlorella vulgari) suspension and mix with 1: 3 volume ratio, and form algae-alginate mixed solution of 3% with the solution of sodium alginate of sterilized 4% (W/V).With this algae-alginate mixed solution is the pvc pipe of 2.75mm by diameter, peristaltic pump with one 8 passage, slowly (speed is 13rpm) pumps in the gel-based solution of 2.5% calcium chloride and 0.3% sodium-chlor, forms the algae ball (algae ball density is greater than water) that diameter is about 3mm.
Make the open container of micropore, printing opacity with the aperture less than the filter screen of 3mm (algae spherical diameter),, pack into the solidified algae ball of making in the container and container is immersed in the pending organotin pollution water body as Fig. 1.Container top is uncovered shape, can allow irradiate light arrive the solidified algae ball of the inside, and installing top simultaneously can not be dipped in the water body fully, prevents that the solidified algae ball from being taken away by current, and staying water enters and contacts with the solidified algae ball of inside from the micropore of vessel surface.Organo-tin compound in the water just can be adsorbed in algae ball surface, and is degraded in microalgae cell.
