Description

A kind of vertical current biology of applying retains the method that system removes acetaminophen
Technical field
The invention belongs to environmental technology field, be specifically related to a kind of vertical current biology of applying and retain the method that system removes acetaminophen.
Background technology:
Water environment pollution problem receives the concern of the masses day by day, and wherein the coexist problem of brought pollution of novel toxic pollutent and ammonia nitrogen starts to manifest.This two classes water pollutant threatens the water environment safety of China by having a strong impact on.The harm of ammonia and nitrogen pollution is long-standing, derives from the degraded of all kinds of nitrogen-containing pollutant.The general mineralized nitrogen time is longer, often builds up at the polluted-water of anoxic, becomes the pollutent of water body total nitrogen 60%.Ammonia nitrogen is the nutrient substance in water body, can cause body eutrophication, is also the main oxygen consumption pollutent in water body, to fish and all toxic property of many hydrobionts.The chronic ammonia nitrogen poisoning harm of ammonia nitrogen to aquatic organism is: reduction of ingesting, decreased growth, tissue injury, reduces the conveying of oxygen between tissue.The poisoning harm of acute ammonia nitrogen is: excited, balance, the tic in water of aquatic organism performance, severe patient is even dead.Therefore, people conduct extensive research for the improvement of ammonia and nitrogen pollution.
And the novel toxic pollutent of another large class is if Non-steroidanalgetic drug is (hereinafter referred to as antiphlogiston, NSAIDs) start to be widely used in daily life, Non-steroidanalgetic drug avoids the various disadvantages of traditional antiphlogiston, in order to alleviate the pain and infection that various illness brings.At present existing over one hundred kind is one of the fastest types of drugs of global evolution.According to the latest survey data presentation that KaloramaInformation issues, the market scale of global pain therapy medicines in 2006 and instrument has reached 26,000,000,000 dollars, expects 2010 and will rise to more than 330 hundred million dollars.It is wherein the share that the medicine of representative has occupied NSAIDs market more than 90% with acetaminophen.This AID is in manufacture and usage process, and a part enters natural water along with waste water, and major part is with medicine after human body is edible, and be not absorbed by the body decomposition, with the movement entered environment of the mankind.Due to its stability and antimicrobial characteristic, degradation time is longer, causes accumulating gradually in water surrounding.
The function of acetaminophen is some physiological function promoting or suppress human body or animal.After the product of this medicine through body metabolism or the residue entered environment without metabolism, still the normal physiological function of likely interference environment biology, due to its water body dissolubility, strong with sewage transport property.The western countries such as European Union have been found that its potential information requirement and the accumulative murder by poisoning of organism, interference are poisoned.Although be that a series of antiphlogistons of representative have certain degradation property with ACETAMINOPHEN, but enter the feature of water body and required degradation time length in a large number, cause the clearance of the type pollutent in down-stream treatment facility low, thus constantly accumulate in water body environment.Become new toxic source of pollution.
Process day by day serious ammonia and nitrogen pollution, allowed the water treatment system energy consumption that can't bear the heavy load increase severely, and the appearance of emerging pollutant, the pressure processed will be increased the weight of further.Therefore, exploitation one is directly applied for community or country sewage pre-treatment, the water treatment system that acetaminophen can transform again the novel energy-saving environment-friendly of ammonia nitrogen can be removed, be not only conducive to alleviating improving and cannot cut dirty Urban Water pollution situation, also contribute to the safety improving water surrounding.The development of following 3-5 distributing water technology is had great importance.
