Description
Technical field
The present invention relates to the preparation of flocculant, specifically a kind of preparation and application administering flocculant for wawter bloom。
Background technology
In recent years, global economy development, environmental problem becomes increasingly conspicuous。The discharge wantonly of industry, agricultural and sanitary sewage, the nutrient (mainly N and P) in aquatic ecosystem increases sharply, and causes body eutrophication, destroys ecological balance and the self-purification capacity of water body。At present, body eutrophication the wawter bloom caused has become the important environmental problem of global concern。Microcystin (microcytins, MCs) that some wawter bloom algae can produce to have harm in growth and catabolic process and volatile abnormal flavour metabolite。Microcystin directly threatens the existence of water fish class and other biology, causes poisoning even dead。The liver of the mankind can be caused damage and can cause hepatocarcinoma by the Microcystin in drinking water source, affects health and the existence of the mankind。The generation of volatility abnormal flavour, causes that drinking water quality declines, adds processing cost, fishery economic causes immeasurable loss, also the aesthetic values of scenic spot is negatively affected。
How fast and effeciently reply and process wawter bloom problem, currently mainly have Physical, chemical method and three kinds of methods of bioanalysis。Physical method mainly has the methods such as By Bubble-floating Method, direct filtration process, ultrasound wave removal method, mechanical removal method and active carbon adsorption；Chemical method mainly has algicide to remove the methods such as algae method, oxidation pre-treatment method and Coagulation Method；Biological control act eats the method such as algae, water plant Water extract to control wawter bloom mainly by aquatic animal, but, there is many drawbacks not yet in these methods。Algae-residue that is as high in Physical moving funds and that ultimately form is difficult to process；Conventional chemical methods instant effect but secondary pollution of water can be caused；Easily affected by external condition during bioanalysis running, and the operation cycle is longer, it is difficult to control。Therefore, study efficient, the economic, practical wawter bloom preventing control method safety to whole world poisons in freshwater and have critically important meaning。
Semen Juglandis is one of world-renowned four big dry fruits, has good nutritive value and brain-healthy effect, is described as " long live ", " Solanum muricatum "。The side-product walnut shell utilization rate of Semen Juglandis is extremely low, and major part directly abandons, and also has part to be used as agriculture fuel, causes great pollution to environment。In recent years, the application of walnut shell is also in continuous developing, and the walnut shell artwork core as sold on market is carved, attractive in appearance as smart as a new pin；Also useful walnut shell makes excellent activated carbon；Walnut shell is for power being greatly improved explosive in explosive etc., and these are all its application in physics。At present, from walnut shell, the also very rare of chemical substance is extracted, not seen in the research preparing walnut shell flocculant。But, utilize modified clay flocculating to have become as a kind of method improving water quality of high-efficiency and economic except algae。
Clay mineral is the layer silicate mineral of a kind of nontoxic pollution-free, have that source is wide, aboundresources, the feature such as with low cost, but can effectively except the clay large usage quantity of algae, sol property is poor, and flocculation frustule ability is relatively low and can form the deposition of waste residue rapidly。With modifying agent, clay is modified improving effect of clay, uses a small amount of clay just can reach same effect。There is also some drawbacks in existing technology, the consumption such as flocculant and clay is big, and the flocculant of use mostly is the medicine of chemosynthesis, it is easy to water body environment is caused secondary pollution。Utilize flocculant prepared by plant to have the advantages such as safe and harmless, degradable, and raw material is sufficient, with low cost。Therefore, explore efficient, environmentally friendly modifying agent and flocculation algicide becomes the hot issue of research。
Summary of the invention
