Description
The present invention relates to a kind of little algae wawter bloom results, dehydration and dry method.
In recent years, because industrial boom, population increase, urbanization increases the weight of, severe environmental pollution, the eutrophication degree aggravation of the many water bodys of China, cause algae particularly blue-green algae breed in a large number, some lake or water body blue algae water bloom take place very serious, but have directly influenced the quality and the availability of water body, and are endangering livestock and human beings'health.Thereby to the inhibition of lake algae or to kill be a vital task of studying on the current environmental protection battle line.Adopt medicament to kill not only cost height, and poor effect, the pollution of water body also can be caused simultaneously.Therefore a kind of method that reduces or control the lake algal grown is all being made every effort to seek by many researchers and research unit.What employing was more at present is exactly to do some processing in algal bloom results back in the lake.Domestic removing at present to algal bloom in the eutrophic lake, the centrifugal methods that adopt more, the water pump of algal bloom with certain power is extracted into algae water in the centrifuge, use centrifuge centrifugal again, algae slurry water content quite high (about 97%) after centrifugal, so both expended the energy, and be difficult to the effect and the complicated operation that reach desirable again, the algae slurry after the results is difficult to drying and utilization.Domestic have Jiangsu in Taihu Lake, Anhui all attempts in Chaohu bloom blue algae is gathered in the crops, they have dropped into very big fund and manpower and have gathered in the crops, effect is not very good.External also few about the reported in literature of results lake algae, have only Japan in an academic discussion, to deliver one piece of paper about the blue-green alga bloom results, its main technique route is that to utilize ship that algae is extracted in the centrifuge on the ship with water pump centrifugal, with fuel the algae burning is being handled then.This method complicated operation, the cost height, consumes energy is quite big, and the smog of burning has caused pollution again to atmosphere, thereby also not very good.
The purpose of this invention is to provide a kind of gathering and handle the preparation method of little algae wawter bloom, easy to implement the method, easy and simple to handle, save the energy, cost is low, has solved the problem of algal bloom results, dehydration.
For achieving the above object, the present invention adopts following technical measures:
1, results
(1) fence
Fence is made up of float, baffle plate, filter cloth.
The size of fence is determined according to following factors: 1, pump energy collecting power; 2, lake table algal layer thickness (usually in 25cm); 3, wind direction; 4, support fixation position; 5, the area of gathering of above-mentioned factor decision.
The duty of fence has two kinds of forms, the one, stationary state, the 2nd, controlled motion state.The former draws a circle to approve the lake surface of determining area, allows the opening of water wing and wind-force, wind direction cooperatively interact, and the little algae wawter bloom in top layer " automatically " is entered in the circle; The latter tightens up water wing more as required after the lake surface of the certain area of delineation, the area of being drawn a circle to approve is progressively dwindled, thereby play the effect of " manpower enrichment ".

(3) the utilization condition of fence enrichment
The blue-green alga bloom of nature has two kinds of situations on the top layer in lake, the one, under the acting in conjunction of illumination, wind-force, current and the self-control of floatability algae own, form the very algal layer of enrichment, this situation is fine results, adopts the mode of direct pump collection; The 2nd, under the situation that above-mentioned factor does not possess simultaneously, bloom blue algae is failed at the algal layer of the top layer in lake formation enrichment, and just forms denseer " water bloom ", and the results difficulty strengthens, and adopts the fence enrichment at this moment.
(4) pump is inhaled
Clog-free water pump is better, 2.2KW, 25m
3, lift 10m.
(5) collection algae groove
Collection algae flute length 1.5m, wide 0.3m, the high 0.10-0.15m of water conservancy diversion actinal surface, back 0.3m.Water pump is placed in the middle of the collection algae groove, and collection algae groove half sinks partly bubbles through the water column, and is convenient to algal bloom and is pumped in the filter.
(6) fixed platform collection
Because be subjected to the influence of wind-force, algal bloom mainly concentrates on a certain bank in lake.Fixedly the gather place of platform is provided with somewhere around here.Build a fixed platform on ground, area 20m
2, can place 2 covers and filter slanted screen.Platform is near the limit, lake, and table top is done a tank a little more than lake surface at the filtered fluid delivery port of platform, is convenient to filtered fluid and runs into a lake.
(7) movable platform (collecting ship) is gathered
Because the littoral band distance in some lakes is longer, it is not enough gathering by fixed platform, thereby must adopt movable platform (utilizing ship) to gather in the crops.On the ship both sides algal bloom grabber is set, in the algae that grabber is collected sucks filter on the ship with pump, filters.Collecting platform is arranged on the afterbody of ship, ship is reached the maximum place of algal bloom gather in the crops.
(8) gravity slanted screen
The gravity slanted screen is installed on fixed or movable platform, the long 2.5-5.0m of slanted screen, wide 0.8-1.0m slanted screen setting angle is advisable for the 20-45 degree.
2, dehydration
(1) sieving
Wire screen generally adopts nylon gauze to filter filter cloth.Specification can be according to collecting season, the amount that wawter bloom takes place, and the screen cloth of employing different size is generally between the 0.125-0.035mm of aperture.
(2) clean
The purpose of cleaning has two, one, and removal of contamination improves the efficient that harvests drying; The 2nd, improve the purity of material, the intermediate product after the dehydration and even the quality of dried harvested product are improved.The mode of cleaning adopts lake water or running water drip washing respectively according to the character of wawter bloom.
(3) dehydration
Dewatering type has two kinds: a kind of is the plate compression method: adopt Chamber Type Diaphragm Filter Press (MXG10/800UK type) to dewater, with the algae slurry of results, go into to carry out filter-press dehydration in the sheet frame filter press with infusion.Another kind is the natural filtration method: the algae slurry of gathering is placed in the algae basket that is lined with filter cloth dewater.
Collection algae basket size is 400 * 300 * 250mm.The aperture of filter cloth is 0.071-0.154mm.
3, drying and powder process
(1) oven dry
Utilize baking room to dry.
(2) solarization or air-dry
Adopt plastic woven cloth or nylon cloth to be growth 1m, wide 2m wooden frame, above the blue-green algae of results was tiled in, thickness 1-2cm was advisable, and directly dried naturally under sunshine or air-dry.
(3) plastic tunnel airing
Utilize plastic tunnel, use the iron wire backguy in booth, spacing 50-100cm is coated in algae mud on woven cloth or the nylon cloth uniformly, and thickness is advisable with 1-2cm, hangs over the iron wire airing then.In case of necessity, an air exhauster can be set in booth, be convenient to faster drying.State inner drying algae (mainly being meant the drying of spirulina) majority is to utilize atomized drying at present, and minority adopts and dries.Utilizing plastic tunnel to hang to dry algae also was out of use at home, this method can solve and give the difficulty that is tiled in airing under the sun under long-term rainy day in summer or the shower weather condition, reduced floor space simultaneously, and dry algae powder mass ratio flat dry good on the ground.
(4) powder process
The algae sheet (piece, grain) that drying is good is ground into powder with cracker, and granularity 80 orders are packed with the woven bag that is with the polyacrylic film liner then.Covering light in place dry, shady and cool, that ventilate preserves.
The present invention compared with prior art, have the following advantages and effect: applicability is strong, and is easy and simple to handle, saves the energy, treatment effect is good.The gravity slanted screen is significantly less than the price of centrifuge, and also than easy many of centrifugal process, the effect in results, dehydration is better than centrifugal in the operation, dewater and algae mud water content can reach 90-92%, be convenient to drying like this.The algae powder of preparation can be used as feed and fertilizer, also can be used as the raw material that extracts the product that becomes more meticulous.
