Description
Technical field
The present invention relates to administer algae water technical field, relate in particular to a kind of water head site Hu Ku filter algae net, be applicable to drinking water seedbed water surface algae and remove on a large scale, there is the advantage of high efficiency, low maintenance cost.
Background technology
In the various pollution problems of storehouse, lake water ecological environment, body eutrophication (Eutrophication) is that one of maximum outstanding problem occurs the most generally, endangers, affect and restricting the coordinated development of economic society, become one of the most serious main Environmental Problems that the world today faces, and more and more caused people's great attention.
Body eutrophication refers to that the inorganic nutrients things such as biological required nitrogen (N), phosphorus (P) enter the water body of the relative closures such as lake, river mouth, bay in a large number, under suitable external environment combined factors effect, cause that algae breeds rapidly, cause the phenomenon of breakout of water bloom.Meanwhile, also may cause water body to occur peculiar smell, cause water quality deterioration.
Under field conditions (factors), lake also can be transitioned into eutrophic state from poor nutritional status, but this natural process is very slow.Anthropogenic discharge can occur at short notice containing industrial wastewater and the caused body eutrophication of sanitary sewage of nutriment.When eutrophication phenomenon appears in water body, planktonic algae amount reproduction, forms wawter bloom.Because the color of dominant planktonic algae is different, the water surface often presents blueness, redness, brown, milky etc.
In China lake, there are after algae pollution problem various algae collecting devices and kill algae net and arise at the historic moment.The problems such as but traditional algae collecting device ubiquity efficiency is low, energy consumption is high, and area coverage is little, are unfavorable for long-term operation maintenance.And kill the removal that algae net is used for the algae such as sewage and lake, its chemical composition of killing in the algicide that algae adheres to is on the net not suitable for throwing in and using at water head sites such as reservoirs.Therefore, for the large-area algae interception of the higher water head site of water quality requirement, need to take new filtration Interception Technology.
Summary of the invention
The shortcoming of prior art in view of the above, target of the present invention is to provide the filter algae net that a kind of running cost is lower, area coverage is large, be applicable to water head site Hu Ku, in order to effective interception algae, reduction algae bio amount.The described filter algae net that is applicable to water head site Hu Ku, comprise screen pack, support ball float and sinking sinker, it is simple and reasonable for structure, compact, has made up the vacancy of the physical filter algae net that is not applicable to water head site Hu Ku at present, and its component have the feature of easy replacement simultaneously.Realized that raw material sources are extensive, production technology is simple, component are easily replaced, production maintenance is with low cost, do not affected original water quality, the good advantage of algae filter effect.
To achieve the above object of the invention, first aspect present invention provides a kind of physics filter algae net that is applicable to water head site Hu Ku, comprise and support ball float and catch net, described support ball float is positioned at described catch net top, described catch net bottom is provided with sinking sinker, the material of described support ball float is wick, and the material of described catch net is oil absorbent material.
Preferably, described catch net comprises multilayer oil absorbent material.
Concrete, the size of described catch net can be adjusted according to the depth of water of water head site Hu Ku and interception width.
The material of described sinking sinker is the plumbous rope of counterweight, the plumbous rope of counterweight is set in the bottom of catch net and makes the vertical subsidence smoothly of described catch net, to guarantee the vertical extended configuration of dictyosome, prevents washing away of wave simultaneously.
Described wick, as supporting ball float, can be adjusted length according to actual conditions, to guarantee that wick can be fixed on the surface of water, is conducive to the algae on absorption and interception water body top layer.
The present invention is to the material of oil absorbent material and wick without specific (special) requirements, and described oil absorbent material and wick all can obtain by commercially available approach.
Second aspect present invention provides the application of described water head site Hu Ku filter algae net in water head site large-area alga interception field.
Third aspect present invention provides a kind of and utilizes described water head site Hu Ku filter algae net to carry out physics filter algae method to water head site Hu Ku, and its concrete grammar is, by water (flow) direction, described water head site Hu Ku filter algae net to be vertically placed on to the delivery port of water head site.
Preferably, the supply volume of described water head site Hu Ku filter algae net is one to three, and concrete supply volume adjustment is according to being: algae granule number is 5.0 * 10
6individual with one of interior input; 5.0 * 10
6~ 5.0 * 10
7two of individual inputs; 5.0 * 10
7three of individual above inputs.
Preferably, 35% of the height >=depth of water of described catch net.
Preferably, the width of described catch net is as the criterion can cover the described delivery port water surface completely.
Concrete, due to reasons such as water body flow and water level fluctuations, described catch net is when real work, it is shaped as arc, the width of catch net can be greater than the developed width of delivery port, and those skilled in the art can be according to actual conditions, and appropriateness is adjusted the width of catch net.
Preferably, the replacement frequency of described water head site Hu Ku filter algae net is 3-7 days in summer, winter 20-30 days.Different according to season, the frequency that filter algae net is changed is distinguished to some extent.Summer is owing to fully having the condition of algae Adaptable growth, algae reproduction speed, the replacing of therefore once filtering algae net in every 3-7 days; Winter, algae reproduction speed was more slow, the replacing of once filtering algae net in every 20-30 days.
Tool of the present invention has the following advantages:
(1) innovation.There is not on the market being at present applicable to the algae interception equipment of storehouse, water head site lake type, of the present inventionly occur having filled up this vacancy.
(2) simple and reasonable for structure, compact.Raw material sources of the present invention extensively, have the advantages that easily to purchase.Make synthesis technique and part replacement also very simple simultaneously.
(3) maintenance cost is low, workable.Once the present invention is come into operation except regular replacing without carrying out regular maintenance and Non-energy-consumption cost.
(4) adapt to large water surface operation.Draft of the present invention can reach 2 meters, and working width can be adjusted length according to footprint, applicable to the interception of the algae scale of large-scale water head site Hu Ku.
(5) regulation effect significantly, on water quality without impact.The present invention adopts the method for physics interception, and the method can not exert an influence to original water quality.
