Description
本發明是有關於一種水處理設備，且特別是有關於一種能有效截除水中蛋白質，以延長膜使用壽命，且能提供良好循環水質、以提高飼養物存活率的循環水系統之液泡分離器。 The present invention relates to a water treatment device, and more particularly to a bubble separator for a circulating water system capable of effectively removing protein in water to prolong the service life of the membrane and providing good circulating water quality to improve the survival rate of the feed. .
申請案號第101496697號「高密度養殖循環水的處理設備」發明專利申請案，為本案發明人先前向 鈞局提出申請的發明專利案。該種養殖循環水的處理設備包含有至少一養殖槽、一曝氣單元、一殺菌單元、至少一循環水處理槽、複數個膜過濾單元、一迴水單元及一噴洗單元。該種處理設備能讓養殖槽內的水體在曝氣後，有充足的溶氧量之外，也能有效地將殘餌及排泄物上浮溢流出槽體外，更配合殺菌單元提供微量的臭氧，以及在該養殖槽的板體內部襯有抗菌材料層，可有效避免病毒、細菌生成，因此能提供優良的養殖水體，以提高生物養殖密度及活成率。 Application No. 101496697, "Processing Equipment for High-density Aquaculture Circulating Water Treatment" invention patent application, is the invention patent file previously filed by the inventor of the present invention. The processing device for circulating circulating water comprises at least one culture tank, an aeration unit, a sterilization unit, at least one circulating water treatment tank, a plurality of membrane filtration units, a backwater unit and a spray unit. The treatment device can make the water body in the culture tank have sufficient dissolved oxygen amount after aeration, and can effectively float the residual bait and excrement to flow out of the tank body, and further provide a trace amount of ozone with the sterilization unit. The lining of the plate body of the culture tank is provided with an antibacterial material layer, which can effectively prevent the formation of viruses and bacteria, thereby providing an excellent aquaculture water body to increase the biological breeding density and the survival rate.
但是，在水產養殖過程中，魚體上不免會因新陳代謝而自然地分泌並排放出黏液，這些黏液通常會凝結水中的細小殘餌與魚隻排洩物，並含有大量不同成份的蛋白質，雖然一部份的黏液在排出養殖槽後，可以迅速地分解為氨氮，並通過後續的硝化菌進行硝化作用來脫除，但大部份的黏液則被泵送到膜過濾單元的過濾室，這些黏液會很快地附著在濾膜的表面，造成膜孔的堵塞，使得膜通量降低，也導致循環水的產水率快 速衰竭，這時，即使利用膜過濾單元上方的噴洗單元來對膜面來進行沖洗清潔，也很難在短暫地時間內有效地除去濾膜表面的黏膜層，造成濾膜喪失應有的固液分離效能。 However, in the aquaculture process, the fish body will naturally secrete and discharge mucus due to metabolism. These mucus usually condense the small residue and fish excrement in the water, and contain a large amount of protein of different ingredients, although one After the mucus is discharged from the culture tank, it can be rapidly decomposed into ammonia nitrogen and removed by subsequent nitrification, but most of the mucus is pumped to the filter chamber of the membrane filtration unit. Will quickly adhere to the surface of the membrane, causing blockage of the membrane pores, resulting in reduced membrane flux, which also leads to faster water production of circulating water. Rapid depletion. At this time, even if the membrane surface is rinsed and cleaned by the spray unit above the membrane filtration unit, it is difficult to effectively remove the mucosal layer on the surface of the membrane in a short period of time, causing the membrane to lose its proper solidity. Liquid separation efficiency.
其次，養殖槽內比重較大的殘餌、魚蝦排泄物及固體懸浮顆粒(SS)，通常無法正常的溢流排出養殖槽外，所以，會在曝氣單元的曝氣作用下，形成上浮於水體液面的泡沫，這些泡沫一旦堆積成有機廢物層後，就會在養殖槽內快速地分解成氨氮，而後續的膜過濾單元的濾膜係採用UF膜(Ultra Filtration，超過濾膜)為主，但UF膜對於氨氮的截留效果不高，如此一來，通過濾膜的循環水在泵送回養殖槽後，就會造成槽體內的水質氨氮濃度提高，飼養物的存活低也相對驟減。 Secondly, residual baits, fish and shrimp excrement and solid suspended particles (SS) with a large proportion in the culture tank are usually not overflowing out of the culture tank, so they will form up and float under the aeration of the aeration unit. In the foam of the water surface, once the foam is deposited into the organic waste layer, it will be rapidly decomposed into ammonia nitrogen in the culture tank, and the membrane of the subsequent membrane filtration unit is UF membrane (Ultra Filtration). Mainly, but the UF membrane does not have a high interception effect on ammonia nitrogen. As a result, the circulating water passing through the membrane is pumped back to the culture tank, which will cause the ammonia nitrogen concentration in the tank to increase, and the survival of the feeder is relatively low. Suddenly.
據上，為更提高養殖物的存活率，有必要再提升養殖之維生系統。 According to the above, in order to improve the survival rate of the culture, it is necessary to upgrade the breeding system.
因此本發明所提供之一種循環水系統之液泡分離器，該液泡分離器是接設在膜過濾單元的一側，使養殖水在尚未進行膜過濾之前，能藉由泡沫吸附分離方式來預先去除水體中的膠狀黏液與懸浮微粒，防止膜過濾單元的濾膜被魚體所分泌的黏液堵塞，以維持濾膜應有的固液分離效能，俾提供優良的循環水質，提高飼養物的存活率，並延長濾膜之使用壽命。 Therefore, the present invention provides a bubble separator for a circulating water system, the bubble separator is connected to one side of the membrane filtration unit, so that the culture water can be pre-removed by foam adsorption separation before the membrane filtration has been performed. The colloidal mucus and suspended particles in the water body prevent the membrane of the membrane filtration unit from being blocked by the mucus secreted by the fish body, so as to maintain the solid-liquid separation efficiency of the membrane, provide excellent circulating water quality and improve the survival of the feeder. Rate and extend the life of the filter.

該微細氣泡產生單元70更包含一氣嘴座77，該氣嘴座77是固設在該中空內殼711的噴口76上方，該氣嘴座77具有一對應於該噴口76的氣嘴771、複數個呈放射狀銜接在該氣嘴771外側的肋板772，及複數個銜接在該等肋板772尾端的鎖接部773，而該中空內殼711的噴口76周側設有數個鎖 接座714，該氣嘴座77的各該鎖接部773配合等數鎖接件774對應鎖固於該等鎖接座714上。 The microbubble generating unit 70 further includes a nozzle holder 77 which is fixed above the nozzle 76 of the hollow inner casing 711. The nozzle holder 77 has a nozzle 771 corresponding to the nozzle 76, and a plurality of nozzles 77.

該本體71還具有一第二外殼713，該第二外殼713是罩設在中空內殼711的另一側，該中空內殼711與第二外殼713之間形成一第二混合室721，而該本體71的入水口73係設於該中空內殼711的一側，該中空內殼711的另一側設有一可將處理水噴送至混合室721的第二噴口78，該第二噴口78是對應於另一空氣管74，以快速產生微細氣泡。 The body 71 further has a second outer casing 713.

如第2、3圖所示，當水液經由該入水口73泵送至該混合室72時，經由該等空氣管74進入的空氣導入該氣嘴座77並由氣嘴771噴出，此時，水與空氣管74所抽送入的氣體在混合室72、第二混合室721中產生充份地混合攪拌作用，進而形成帶有大量微細氣泡的水體，並由該等迴水口75洩流至該筒槽40的容水室42，這時則促使水體中的黏液、殘餌、排洩物與懸浮顆粒能積聚在氣泡表面並向上推升，再經由該排沫孔46上的收集管61匯送至該集沫槽60內，而與氣泡到達分離界面後的水體則向下流動，最後通過該筒槽40的出水管44排放到該膜過濾單元30中。 As shown in FIGS. 2 and 3, when the water liquid is pumped to the mixing chamber 72 through the water inlet 73, the air that has entered through the air tubes 74 is introduced into the nozzle holder 77 and ejected by the nozzle 771. The gas pumped by the water and air tube 74 is sufficiently mixed and stirred in the mixing chamber 72 and the second mixing chamber 721 to form a water body with a large number of fine bubbles, and is discharged from the water return port 75 to The water receiving chamber 42 of the canister 40, at this time, promotes the accumulation of mucus, residual bait, excrement and suspended particles in the water body on the surface of the bubble and pushes up, and then sends it to the collecting pipe 61 on the discharging hole 46 to In the collecting tank 60, the water body after the bubble reaches the separation interface flows downward, and finally is discharged into the membrane filtering unit 30 through the outlet pipe 44 of the tank 40.
因此，本發明之循環水系統之液泡分離器，在養殖水的循環過程中，處理水先經過該微細氣泡產生單元100利用水與氣體之充份攪拌混合，藉泡沫和水之比重差而分離，且泡沫產生張力使得水中懸浮的膠狀體、纖維素、氨氮、殘餌和糞便則隨著泡沫往上浮升，進而經由排沫孔46通過收集管61排放至集沫槽60，而水體則經由該出水管44回流至該養殖槽10，如此，通過該液泡分離器100的處理下，即可去除養殖水中的膠狀黏液，以分離其中的氨氮，進而提高魚蝦存活率。 Therefore, in the bubble separator of the circulating water system of the present invention, during the circulation of the aquaculture water, the treated water is firstly mixed and mixed by the microbubble generating unit 100 by using water and gas, and separated by the difference in specific gravity between the foam and the water. And the foam generates tension so that the colloidal, cellulose, ammonia nitrogen, residual bait and feces suspended in the water rise upward with the foam, and are discharged to the collecting tank 60 through the collecting tube 61 through the discharging hole 46, and the water body is passed through The outlet pipe 44 is returned to the culture tank 10, so that the colloidal mucus in the culture water can be removed by the treatment of the bubble separator 100 to separate the ammonia nitrogen therein, thereby improving the survival rate of the fish and shrimp.
另外，再配合第4圖所示，該液泡分離器100更包含一樞接套管80，該樞接套管80串接在該筒槽40的出水管44上，且該出水管44係呈倒L型，當調整該樞接套管80，得以改變該出水管44的一出水端441相對於該出水口440的高度，當出水管44呈假想線所繪狀態時，此時筒槽40內的液壓與液位係降低，這意謂著氣泡上推的速度會減慢，相對的氣泡與水體的接觸時間則增長，液泡分離器100對於有機物的去除率就更高，反之則否，所以，利用調整該出水管44之出水端441位高，就能改變筒槽10內水體的液位高度與壓力，進而控制泡沫吸附懸浮微粒後向上推升的高度，俾將泡沫快速排出筒槽40外，並藉以調節液泡的分離效率。 In addition, as shown in FIG. 4, the bubble separator 100 further includes a pivot sleeve 80 which is serially connected to the water outlet pipe 44 of the cylinder 40, and the outlet pipe 44 is In the inverted L shape, when the pivot sleeve 80 is adjusted, the height of a water outlet end 441 of the outlet pipe 44 relative to the water outlet 440 can be changed. When the outlet pipe 44 is in a state drawn by an imaginary line, the groove 40 is at this time. The internal hydraulic pressure and liquid level are reduced, which means that the speed of pushing up the bubble will be slowed down, the contact time of the opposite bubble with the water body will increase, and the removal rate of the organic matter by the bubble separator 100 will be higher, otherwise, Therefore, by adjusting the height of the water outlet 441 of the outlet pipe 44, the liquid level and pressure of the water in the tank 10 can be changed, thereby controlling the height at which the foam adsorbs the suspended particles and then pushing up, and the foam is quickly discharged out of the tank. 40, and to adjust the separation efficiency of the bubble.
其次，再如第2圖所示，該液泡分離器100更包含有一臭氧產生單元90，該臭氧產生單元90設置在筒槽40外，具有一對應該導氣孔45的臭氧排放口91，以適時地將臭氧(O3)打入該容水室42內進行殺菌。 Next, as shown in FIG. 2, the bubble separator 100 further includes an ozone generating unit 90 disposed outside the cylindrical tank 40 and having a pair of ozone discharge ports 91 to be used for the air guiding holes 45. Ozone (O 3 ) is driven into the water chamber 42 for sterilization.
如第5圖所示，至於，在第2圖中僅使用一支微細氣泡產生單元70來進行氨氮分離，依照養殖水的水質狀況，可在筒槽40內部增設更多支的微細氣泡產生單元70，藉此，以隨水量之增加而可加速進行氨氮分離。 As shown in Fig. 5, in the second drawing, only one microbubble generating unit 70 is used to perform ammonia nitrogen separation, and according to the water quality of the culture water, more microbubble generating units can be added inside the tank 40. 70, whereby the ammonia nitrogen separation can be accelerated with an increase in the amount of water.
如第6圖所示，本發明之循環水系統之液泡分離器的第二實施例，該液泡分離器100是裝設在該養殖槽10的一側，以去除養殖水中的泡沫黏液，且經過液泡分離後的養殖水，再溢流至一設有包埋式硝化菌(Nitrosomonas)的硝化處理槽20內進行硝化反應，並通過一膜過濾單元30進行固液分離。該第二實施例中，將液泡分離器100接設在養殖槽10的一側，在養殖水尚未經過硝化處理或膜過濾處理之前，就預先去除養殖水中 的膠狀黏液，除可降低膜過濾單元30之膜孔堵塞之外，也可降低動力耗損。至於該液泡分離器的結構以及使用功能皆與前述實施例相同，於此不再多加說明。 As shown in Fig. 6, in a second embodiment of the bubble separator of the circulating water system of the present invention, the bubble separator 100 is installed on one side of the culture tank 10 to remove foamy mucus in the culture water, and The culture water after the bubble separation is further overflowed into a nitrification tank 20 provided with Nitrosomonas for nitration reaction, and solid-liquid separation is performed by a membrane filtration unit 30. In the second embodiment, the bubble separator 100 is connected to one side of the culture tank 10, and the culture water is removed before the culture water has been subjected to the nitrification treatment or the membrane filtration treatment. In addition to reducing the clogging of the membrane pores of the membrane filtration unit 30, the colloidal mucus can also reduce the power consumption. The structure and function of the bubble separator are the same as those of the foregoing embodiment, and will not be further described herein.
歸納上述，為改善以往UF膜無法完全過濾氨氮之使用問題，本發明之循環水之液泡分離器，不論是接設在養殖槽10的一側，或是接設在膜過濾單元30的一側，利用該微細氣泡產生單元100將水與氣體產生充份地攪拌混合作用，藉泡沫和水之比重差而分離，且泡沫產生張力使得水中懸浮的膠狀體、纖維素、殘餌和糞便則隨著泡沫往上浮升，進而經由排沫孔46通過收集管61排放至集沫槽60，而水體則經由該出水管44回流至該養殖槽10或送至膜過濾單元30，如此，通過該液泡分離器100的處理下，即可去除養殖水中的膠狀黏液，以分離其中的氨氮，因此，當養殖水的氨氮值降低之後，魚的存活率則相對提高。而且，將液泡分離器100接設在膜過濾單元30一側，更可減低濾膜之膜孔阻塞問題，且更能延長膜的使用壽命。 In summary, in order to improve the use problem that the conventional UF membrane cannot completely filter the ammonia nitrogen, the circulating water bubble separator of the present invention is connected to one side of the culture tank 10 or to one side of the membrane filtration unit 30. By using the microbubble generating unit 100, the water and the gas are sufficiently stirred and mixed, separated by the difference in specific gravity between the foam and the water, and the foam generates tension so that the colloidal, cellulose, residual bait and feces suspended in the water are As the foam rises upward, it is discharged to the foam collecting tank 60 through the collecting pipe 61 through the drain hole 46, and the water body is returned to the culture tank 10 via the water outlet pipe 44 or sent to the membrane filtration unit 30, and thus, Under the treatment of the bubble separator 100, the colloidal mucus in the culture water can be removed to separate the ammonia nitrogen therein. Therefore, when the ammonia nitrogen value of the culture water is lowered, the fish survival rate is relatively increased. Moreover, the bubble separator 100 is connected to the membrane filtration unit 30 side, which can reduce the membrane pore blocking problem of the membrane and prolong the service life of the membrane.
以上所述者，僅為本發明之數個實施例而已，當不能以此限定本發明實施之範圍，即大凡依本發明申請專利範圍及發明說明內容所作之簡單的等效變化與修飾，皆應仍屬本發明專利涵蓋之範圍內。 The above is only a few embodiments of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are all It should remain within the scope of this invention.
