Description

A kind of method and system for processing the algae organic wastewater containing Algae toxins
Technical field
The present invention relates to field of waste water treatment, and in particular to a kind of process containing Algae toxins algae organic wastewater method and System.
Background technology
The fast development of social economy and the continuous quickening of social process of industrialization, it is increasingly serious along with environmental pollution. Wherein prominent is that the irrational life of people, the mode of production result in the nutrient salts such as nitrogen in waters, phosphorus and be enriched with a large number, is caused Global waters eutrophication is increasingly serious, causes algae distorted proliferation, and wawter bloom occurs.In the last few years, China's algal bloom frequency Send out.Algae organic wastewater containing Algae toxins is mainly by the substantial amounts of carbon hydrate produced in algal bloom its metabolic process Cracking after thing, protein, Microcystin and its death is discharged into the composition of the Organic substance in water, and this is also to cause water pollution Principal element.Research finds that 80% blue-green alga bloom can detect secondary metabolite --- Microcystin (microcystins).This is the ring-type heptapeptide compound that a class has biological activity, and what other metabolism of it and algae were produced has Machine thing is compared, and hazardness is maximum.Microcystin have very strong liver, kidney and other organs toxicity and promotees carcinous, is recognized To be seriously to threaten the environmental contaminants of wild animals and plants and human health and obtain extensive concern.To ensure drinking for resident Water security, the United Nations has formulated drinking water Microcystin limit standard, and its highest allows content for 1 μ g/L, China's Ministry of Public Health This standard is continued to use in calendar year 2001, and has specified that Microcystis aeruginosa Algae toxins are one of drinking water quality essential items for inspection in 2006.With Increasingly sharpening for water body eutrophication degree frequently to break out with algal bloom, Algae toxins pollution be China or even the world most One of main environmental problem, seriously threatens mankind's drinking water safety, water ecosystem and mankind's public health security, into To affect a key factor of sustainable utilization of water resource and restriction society and economy sustainable development, it is to ecological balance shadow Ring and loss is difficult to the appraisal.Therefore, how Algae toxins are safely and effectively removed, so as to control Algae toxins concentration in water body, An environmental science difficult problem of whole mankind's facing is become.
Microcystin is the ring-type heptapeptide that a class has biological activity, and with interval double bond, stable chemical nature is acidproof resistance to Alkali, the coagulation of general water treatment technology, precipitates, boils (even if 300 DEG C of high temperature) and also its effective removal can not be belonged to into difficult degradation Biological organic toxin, can retain in natural water environment for a long time.The method for eliminating Algae toxins in water body at present is main There are Physical, chemical method and bioanalysises etc., but Physical and chemical method have in actual applications certain limitation, it is such as living Property the Physical such as carbon adsorption and membrane filter method it is relatively costly, there is certain difficulty in concrete operations and enforcement, and effect is unstable It is fixed, and chemical method easily causes the Environmental Residues of poisonous and harmful substance, causes the generation of secondary pollution, and water ecological environment is brought not The impact of profit.In the last few years, studies have found that bacterial degradation Algae toxins often have low cost, efficiency is higher, be not likely to produce two Secondary pollution and beneficial to the advantages of restoration of the ecosystem, therefore be that a kind of environmentally friendly very promising Algae toxins remove skill Art, widely attracts attention in recent years, but the environmental safety due to antibacterial itself etc., so as to from practice also There is larger gap.
In a word, these methods for removing Algae toxins are typically necessary the input energy or chemical reagent, and not only input cost is huge Greatly, it is and cumbersome.In the face of China all there is algal bloom in numerous large-size lakes, have substantial amounts of Algae toxins and other algae to have Organic pollutants need to process, and existing these methods either have very big difficulty from practical operation or economic investment.
Microbiological fuel cell is a kind of new wastewater through organic matter treatment technology, and it can process wastewater through organic matter Electric current is produced simultaneously.Its ultimate principle is, with microorganism as catalyst, the Organic substance in waste water to be directly converted into the dress of electric energy Put, antibacterial passes to negative electrode in anodic oxidation Organic substance, the electronics of generation by external circuit, the proton in solution then passes through proton , to movable cathode, last proton, electronics is combined with terminal electron acceptor in negative electrode for exchange membrane or solution medium, completes whole life The electronic transfer process of thing electrochemistry.
The content of the invention
To solve the above problems, the invention provides a kind of process contains the method for the algae organic wastewater of Algae toxins and is System, with reference to the characteristics of microbial treatments and electrochemistry, while Microcystin and other algae organic pollutions are removed, produces Electric energy is given birth to, the recycling of algae organic wastewater resource has been realized, the also removal for Microcystin have found a kind of new Effective method.
For achieving the above object, the technical scheme taken of the present invention is:
A kind of system for processing the algae organic wastewater containing Algae toxins, including container, are filled with the container and contain algae The algae organic wastewater of toxin Microcystin-RR and other algae Organic substances, side is provided with anode in the container, Interior opposite side is provided with negative electrode, and the anode and negative electrode are connected with external circuitses resistance by power line, and the container is adopted to be had Machine glass material, the pmma material is polymethyl methacrylate, and the container upper end is provided with gas collection by breather Bag.
Preferably, the container upper end is additionally provided with and changes the mouth of a river, changes on the mouth of a river and is connected with lid.
Preferably, the anode is made up of carbon brush, and negative electrode is the carbon cloth composition for scribbling platinum pt catalyst, and conductive material is titanium Silk.
Present invention also offers a kind of process the algae method for processing organic wastewater containing Algae toxins, comprise the steps:
S1, the algae organic wastewater containing Algae toxins Microcystin-RR and other algae Organic substances is placed in into installation Have in the container of negative electrode and anode, and outer meeting resistance is provided between negative electrode and anode;
, at anodic oxidation Organic substance (including Microcystin), the electronics of generation is passed to by external circuit for S2, microorganism Negative electrode, the proton in solution then by solution medium to movable cathode, with terminal electron acceptor in negative electrode tie by last proton, electronics Close, complete whole bioelectrochemical electronic transfer process, complete the removal of algae Organic substance.
