Abstract
The invention provides a method for eliminating large-area lake-flooding peculiar smell substances in situ. In the method, nanometer air bubbles are loaded on non-toxic and harmless solid particles in a certain mode to prepare a composite material, and the composite materials are sprinkled to a lake-flooding water body by a mechanical device to remove the peculiar smell substances such as geosmin, dimethyl isoborneol and the like in large area with high efficiency. The method has the advantage of high efficiency of removal of the peculiar smell substances, is convenient to use, and is suitable for removing the peculiar smell substances from lakes and natural water bodies.
Description
Technical field:
The present invention relates to a kind of original position and eliminate the method for the general smell substance in big area lake, belong to the environmental pollution improvement field.
Background introduction:
Body eutrophication is a global problem, owing to enter the continuous increase of the nutritive elements such as nitrogen phosphorus of water body, the body eutrophication problem is more and more serious, and the outburst of blue-green algae is also more and more frequent.Blue-green algae not only can secrete native musty metabolic substds such as native smelly element, the different borneol of dimethyl, cause unhappy on the sense organ, and break out in a large number, gather and death after, run into suitable temperature, hydrologic condition also can with the organism generation biochemical reaction in the bed mud, discharge smell substances such as sulfide, dimethyltrisulfide, form memnonious " Heisui River group ", distribute stench.The water body stink not only makes deteriorating water quality, causes the raising of cost of water treatment, and can cause people's panic psychology on every side, and HUMAN HEALTH is constituted a threat to, and also can cause damage to fishery and tourism simultaneously.Along with the aggravation of eutrophication problem, water body peculiar smell problem becomes more and more serious.
At present the peculiar smell removal method in the water is mainly contained chemical oxidization method, absorption method, biological process etc. both at home and abroad.Chemical oxidization method is by adding the smell substance in the oxidation water bodys such as oxygenant such as dioxide peroxide, clorox, potassium permanganate, the odor removal efficient height, but these chemical substances can have a negative impact to the biology in the water, produce secondary pollution; Absorption method is the smell substance that utilizes in the adsorbents adsorb water bodys such as gac, and reaching the smelly purpose that disappears, but the cost height should not big area be promoted the use of; Biological process is to utilize predations such as microorganism, protozoon to discharge the algae of smell substance, perhaps utilize the microbiological deterioration smell substance, reduce the concentration of smell substance, but because the difference of laboratory and natural water body condition, might be obvious in effect under the laboratory condition, effect is relatively poor in natural water body.Therefore, the general peculiar smell removal in the lake technology of seeking a kind of economical and effective, ecological safety and can big area implementing seems very necessary.
Summary of the invention:
The object of the present invention is to provide a kind of original position to eliminate the method for the general smell substance in big area lake, specifically, be to adopt nontoxic solid particulate matter,, be used for the method that big area is eliminated the general smell substance in lake through the prepared matrix material of nano bubble in the certain way load.The solid particulate matter that this method adopts is nontoxic, and wide material sources are with low cost, can remove smell substance efficiently behind the nano bubble in the load.This invention not only can be used for the removal of smell substance in the lake, also can be used in the contaminated river course and the removal of smell substance in the water factory.
Nontoxic solid particulate matter of the present invention, be bank, lake soil or other clay minerals, as sepiolite, wilkinite, kaolin, illite clay, diatomite, attapulgite, zeolite, polynite, talcum, potter's clay, white clay, china clay and earth in one or more.These soil are nontoxic, can not cause secondary pollution to water body.
Nano bubble of the present invention is ozone nanometer bubble, oxygen nano bubble or air nano bubble, and nano bubble has that particle diameter is little, and specific surface area is big, active high characteristics.
The mode of loaded with nano bubble of the present invention is meant by alternating temperature, method ultrasonic or the nano bubble generation device produces nano bubble makes it directly load on the solid particulate matter, also can use natural polymers earlier, handle solid particulate matters as wherein one or more of chitosan and derivative, xanthan gum and derivative thereof, moringa seeds, produce nano bubble through alternating temperature, ultrasonic or nano bubble generation device method again it is loaded on the solid particulate matter.
According to method of the present invention, the absorption folder by solid particulate matter carries effect, make ozone, oxygen or air-stable towards be conveyed in water body or the bed mud, and can stablize stop betwixt.Ozone, oxygen or air load on the form of nano bubble and make matrix material on the solid particulate matter, and the present invention can spill matrix material noted earlier to lake flashing body by spraying mechanisms such as ship, realize that big area, high-level efficiency remove smell substance.

Fig. 2 eliminates the general smell substance in lake---the content figure of native smelly element for carrying out the original position big area with matrix material in the embodiment of the invention 3.
Fig. 3 eliminates the general smell substance in lake---the content figure of the different borneol of dimethyl for carrying out the original position big area with matrix material in the embodiment of the invention 3.
Embodiment
Describe the method that original position is eliminated the general peculiar smell in big area lake in detail below by embodiment.
Take by weighing the 0.2g chitosan, be dissolved in the 200mL water, add bank, the Taihu Lake soil that 2g crosses 180 mesh sieves, be made into suspension liquid, add ozone 30min with ozonizer, ultrasonic then 3min obtains matrix material.
The preparation starting point concentration is native smelly element and the different borneol solution of dimethyl of 200ng/L, establishes two groups of experiments, first group of matrix material 1mL that adds among the embodiment 1, and second group is blank.The content of native smelly element of residue and the different borneol of dimethyl behind the mensuration different time, the result as shown in Figure 1.
Embodiment 3 original positions are eliminated the general peculiar smell in big area lake
Be sprayed on the demonstration area, Taihu Lake with above-mentioned matrix material big area, the content of 7 the smelly elements of sampling point smell substance soil in engineering demonstration front and back, the different borneol of dimethyl is shown in Fig. 2,3, and native smelly element, the different borneol equal size of dimethyl descend significantly.
