Description
Technical field
Chlorophos decomposition apparatus and the method for a kind of fish belong to the food security field, are specifically related to a kind of decomposition apparatus and method of chlorophos.
Background technology
Chlorophos is broad spectrum activity phosphoric acid ester insecticide, the parasitic disease that is mainly used in treating fish in aquaculture.Owing to reusing in a large number for a long time, make a lot of parasites produce serious pesticide resistance to chlorophos.In order not reduce result for the treatment of, can only increase the usage amount of chlorophos, consequence is exactly that the poisoning of fish chlorophos happens occasionally, and more seriously, chlorophos can be attached in the fish body, by the people, is eaten.
Because chlorophos can be converted into dichlorvos under the weak base condition.The activity that directly suppresses cholinesterase in body, have larger toxic and side effect to nervous system, digestive system and the cardiovascular system of human body, and acute and chronic poisoning easily occurs.Therefore, the injury for fear of chlorophos to human body, need to be degraded to chlorophos in aquatic products.
Ge Xiaoqin, the people such as Shen Meifang in 2011 at " aquaculture " magazine the 32nd volume publish an article on the 4th phase " residue detection of chlorophos and degradation analysis in breeding water body ", this article adopts the SPE of HLB pillar to process water sample, carries out chlorophos residue detection and degraded.Article points out, the chlorophos degradation speed under alkali condition is faster, and is verified by experiment, and experimental result shows, when pH value is 9, when the chlorophos degradation speed is greater than pH value and is 7 and 8.
Yet regrettably, this article has just provided the testing result under the different condition, but professional degraded equipment is not provided, especially can not provide a kind of both can carry out fish fresh-keeping, professional equipment and the method for the chlorophos of can effectively degrading again.
Summary of the invention
In order to address the above problem, the present invention has designed a kind of chlorophos decomposition apparatus and the method for fish, provide a kind of both can carry out fish fresh-keeping, professional device and the method for the chlorophos of can degrading again.
The object of the present invention is achieved like this:
The chlorophos decomposition apparatus of a kind of fish, comprise the fish jar body, is arranged on the first water inlet on the fish jar body, the second water inlet and delivery port, and described the first water inlet connects running water pipe by tired wetting system, and the second water inlet connects the alkaline solution pond; Be provided with seal cover in the fish jar bodies top, be provided with gas outlet and dog-house on described seal cover; Be provided with the oxygen feedway in the fish jar body interior.
The chlorophos decomposition apparatus of above-mentioned a kind of fish, the structure that described gas outlet is pressure chamber.
The structure that described gas outlet is the high-pressure cooker plug, when being specially pressure and reaching 1.1 standard atmospheric pressures, by the balancing weight jack-up above pressure chamber.
The chlorophos decomposition apparatus of above-mentioned a kind of fish, described dog-house is provided with lid.
The chlorophos decomposition apparatus of above-mentioned a kind of fish, described delivery port directly connects downcomer.
The chlorophos biodegrading process of a kind of fish comprises the following steps:
Step a, preparation
Tired wetting system fills running water, and is stranded 24h in tired wetting system;
The alkaline solution that in the alkaline solution pond, the configuration pH value is 9;
Step b, degraded work
By injecting the alkaline solution that pH value is 9 in the fish jar body, live fish to be rendered in the fish jar body, seal cover covers the fish jar body, by dog-house, drops into the fish food, opens the oxygen feedway oxygen is provided, and keeps fish to survive in the fish jar body;
After 4h, discharge the alkaline solution in the fish jar body, inject the running water of tired wetting system, and the alkaline solution discharged is detected, if:
Do not contain chlorophos in the alkaline solution discharged, the end-of-job of degrading;
Contain chlorophos in the alkaline solution discharged,, again by injecting the alkaline solution that pH value is 9 in the fish jar body, after 8h, degraded finishes.
The chlorophos biodegrading process of above-mentioned a kind of fish, the alkaline solution that described configuration pH value is 9 is to add slaked lime in running water.
Because the chlorophos decomposition apparatus of fish of the present invention provides the tired wetting system that falls the alkaline solution pond of being sent to a place under guard the chlorophos effect and play neutral living environment effect simultaneously, under the condition that the chlorophos biodegrading process of fish has the pH value best at degradation effect to be 9, carry out, therefore both can carry out fish fresh-keeping, the chlorophos of can degrading again.
