Description
本發明涉及有機廢棄物處理領域,尤其是利用微生物處理有機廢水及汙泥。The invention relates to the field of organic waste treatment, in particular to treating organic wastewater and sludge by using microorganisms.
隨著環境及生態保育的觀念抬頭視,各廠商對於廢液的處理也越來越重視。在廢液的處理上,一般是將有機廢液及無機廢液分類處理。對於有機廢液,可經過濃縮、螯合的處理成泥漿態,此外,更發現透過細菌、真菌等微生物,能依賴有機廢液中的有機質作為碳源,有機營養型微生物會大量生長繁殖,透過細菌、真菌等微生物的增殖、發酵作用、光合作用等,能將有機質分解,而形成所謂的生物汙泥,又稱活性汙泥。With the concept of environmental and ecological conservation rising, manufacturers are paying more and more attention to the treatment of waste liquid. In the treatment of waste liquid, organic waste liquid and inorganic waste liquid are generally classified and processed. For organic waste liquid, it can be concentrated and chelated to form a slurry state. In addition, it is found that microorganisms such as bacteria and fungi can rely on organic matter in organic waste liquid as a carbon source, and organic nutrient-type microorganisms will grow and multiply through The proliferation, fermentation, photosynthesis, etc. of microorganisms such as bacteria and fungi can decompose organic matter to form so-called biological sludge, which is also called activated sludge.
在顯微鏡下觀察,生物汙泥中含有無機物、微生物、原生動物及後生動物等,形成菌團狀的微型生態系統,又稱為膠羽。膠羽較容易被生物界的微細生物,例如藻類、浮游生物等補食,而可作為堆肥之用,其中水分經分離後經淨化的水再放流。據此,能減低對於環境或生態的衝擊。Under the microscope, the biological sludge contains inorganic substances, microorganisms, protozoa and metazoans, etc., forming a micro-ecological system of microbial flora, also known as rubber feather. Gum feathers are more easily supplemented by micro-organisms in the biological world, such as algae, plankton, etc., and can be used as composting, in which the water is separated and purified by purified water. According to this, the impact on the environment or ecology can be reduced.
微生物對於有機廢水的負荷高,能夠處理高濃度的有機廢水,可以減少稀釋所造成的水資源浪費,此外,設備規模小、受季節影響小,能減少設置及營運上的成本。此外,經過處理的生物汙泥可以作為堆肥等作用來利用,更達到環保的效益。Microorganisms have high load on organic wastewater and can handle high concentrations of organic wastewater, which can reduce water waste caused by dilution. In addition, the equipment is small in scale and less affected by the season, which can reduce the cost of installation and operation. In addition, the treated biological sludge can be utilized as a compost, and the environmental benefits are achieved.
然而,每天產生的生物汙泥仍需有足夠的空間來堆置,對於倉儲成本上仍是不小的負擔。目前常用的方式,是將生物汙泥經過脫水、乾燥後,以脫除生物汙泥的水分、減少汙泥的體積,但是每天所產的固態生物汙泥量並沒有減少。另一方式是,將固態生物汙泥輸送至高溫好氧槽,透過加熱、超音波、好氧微生物或加藥等方式的結合,將生物汙泥分解成小分子,再經由微生物分解,或由後生動物的補食。然而,脫水、乾燥、或是以高溫好氧槽進行分解,都需要額外的電力成本。高溫好氧槽更需要設備、藥劑成本、同時也需要廠區有足夠的空間才有辦法設置。However, the biological sludge produced every day still needs to have enough space for stacking, which is still a small burden for storage costs. At present, the commonly used method is to remove the biological sludge and reduce the volume of the sludge after dewatering and drying the biological sludge, but the amount of solid biological sludge produced per day is not reduced. In another way, the solid biological sludge is transported to a high-temperature aerobic tank, and the biological sludge is decomposed into small molecules by a combination of heating, ultrasonication, aerobic microorganisms or dosing, and then decomposed by microorganisms, or by Supplementation of metazoan. However, dehydration, drying, or decomposition with a high temperature aerobic tank requires additional power costs. High-temperature aerobic tanks require equipment and pharmaceutical costs, and also require sufficient space in the plant to have a way to set them up.

光合菌能夠進行除氮、脫硫、脫磷等功能,在適當的酸鹼值下,具有較佳的增值及反應的速率。兼氧槽11中的有機廢水21、光合菌液23之混合物的pH值在6至10之間,較佳為7至9之間,此外,好氧槽13中的第一生物汙泥及芽孢菌液25之混合物的pH值為6至10之間,較佳為7至9之間。如圖1所示,有機廢水及汙泥處理系統更包含一酸鹼值調整槽17,酸鹼值調整槽17與兼氧槽11連接,預先將有機廢水21調整至pH值6至10之間,尤其是7~9之間,之後再透過幫浦或管線將調整過pH值的有機廢水21加以輸送至兼氧槽11。酸鹼值調整槽17能優先將調整環境的酸鹼值為光合菌或芽孢菌易於反應的條件下,以使增殖、反應速率提升。Photosynthetic bacteria can perform functions such as nitrogen removal, desulfurization, dephosphorization, etc., and have a better value-added and reaction rate under appropriate pH values. The pH of the mixture of the organic wastewater 21 and the photosynthetic bacteria 23 in the oxygen chamber 11 is between 6 and 10, preferably between 7 and 9, in addition, the first biological sludge and spore in the aerobic tank 13 The pH of the mixture of bacterial liquid 25 is between 6 and 10, preferably between 7 and 9. As shown in FIG. 1, the organic wastewater and sludge treatment system further includes a pH adjustment tank 17, and the pH adjustment tank 17 is connected to the oxygenation tank 11, and the organic wastewater 21 is adjusted to a pH between 6 and 10 in advance. In particular, between 7 and 9, the pH-adjusted organic wastewater 21 is then sent to the oxygen-containing tank 11 through a pump or pipeline. The pH adjustment tank 17 can preferentially adjust the pH value of the environment to a condition in which the photosynthetic bacteria or the spores are easily reacted, so that the proliferation and the reaction rate are improved.
進一步地,兼氧槽11中的有機廢水21及光合菌液23之混合物的溫度,以及好氧槽13中的第一生物汙泥及芽孢菌液25之混合物的溫度在16℃至40℃,較佳為22至35℃。也就是,在一般氣溫下,光合菌液23及芽孢菌液25都能有效地進行增殖及分解,無需額外加熱,能降低能源的耗費。Further, the temperature of the mixture of the organic wastewater 21 and the photosynthetic bacteria 23 in the oxygen chamber 11 and the mixture of the first biological sludge and the spore liquid 25 in the aerobic tank 13 are at 16 ° C to 40 ° C, It is preferably 22 to 35 °C. That is, under normal temperature, both the photosynthetic liquid 23 and the spore liquid 25 can effectively proliferate and decompose, and the energy consumption can be reduced without additional heating.
以下為實際以四組實驗、對照組經過兼氧槽、好氧槽及泥水分離槽,檢測及放流水的化學需氧量(Chemical oxygen demand,COD)、以及泥水分離槽的汙泥生成率。因為對照示例係直接接收的有機廢水,每次的成分可能不同,因此輔以生物汙泥生成率的差值來比較。實驗示例1係將光合菌液以兼氧槽體積的1/500,並分成每日六小時添加、光合菌液的濃度為10 9CFU/mL、芽孢菌液以好氧槽體積的1/500,並分成每日六小時添加、芽孢菌液的濃度為10 9CFU/mL。實驗示例2係以實驗示例1之光合菌液、芽孢菌液劑量減半添加。實驗示例3係以實驗示例1之係將芽孢菌液替換為有效(Effective Microorganism,EM)菌,即混合芽孢菌、酵母菌、乳酸菌等菌類的混合菌液,其與實驗示例1的芽孢菌液的劑量、濃度相同。實驗示例4係以實驗示例1之係將芽孢菌液替換為枯草菌,其與實驗示例1的芽孢菌液的劑量、濃度相同。以下表1為經六週測試實際量測的結果平均值。 表1 <TABLE border="1" borderColor="#000000" width="_0004"><TBODY><tr><td> </td><td> 放流水COD (mg/L) </td><td> 汙泥生成率 (g MLSS/g COD) </td><td> 汙泥生成率差值 (g MLSS/g COD) </td></tr><tr><td> 對照示例1 </td><td> 55 </td><td> 0.48 </td><td> </td></tr><tr><td> 實驗示例1 </td><td> 56 </td><td> 0.29 </td><td> 0.19 </td></tr><tr><td> 對照示例2 </td><td> 55 </td><td> 0.33 </td><td> </td></tr><tr><td> 實驗示例2 </td><td> 56 </td><td> 0.23 </td><td> 0.10 </td></tr><tr><td> 對照示例3 </td><td> 55 </td><td> 0.49 </td><td> </td></tr><tr><td> 實驗示例3 </td><td> 150 </td><td> 0.37 </td><td> 0.12 </td></tr><tr><td> 對照示例4 </td><td> 55 </td><td> 0.41 </td><td> </td></tr><tr><td> 實驗示例4 </td><td> 150 </td><td> 0.30 </td><td> 0.11 </td></tr></TBODY></TABLE>The following is the actual chemical oxygen demand (COD) of the detected and discharged water and the sludge formation rate of the mud-water separation tank by the four sets of experiments and the control group through the oxygen tank, the aerobic tank and the mud-water separation tank. Since the comparative example is the organic wastewater directly received, the composition may be different each time, and thus the difference in the rate of production of the biological sludge is compared. In the experimental example 1, the photosynthetic bacterial liquid was added in an amount of 1/500 of the volume of the anaerobic tank, and was divided into six hours per day, the concentration of the photosynthetic liquid was 10 9 CFU/mL, and the spore liquid was 1/500 of the volume of the aerobic tank. And divided into six hours a day, the concentration of the spore liquid was 10 9 CFU / mL. Experimental Example 2 was carried out by halving the dose of the photosynthetic bacterial liquid and the spore liquid of Experimental Example 1. Experimental Example 3 is a method in which the spore liquid is replaced with an effective microorganism (EM) strain, that is, a mixed bacterial liquid mixed with a fungus such as a spore, a yeast, or a lactic acid bacteria, and the spore liquid of the experimental example 1 The dose and concentration are the same. Experimental Example 4 The spore liquid was replaced with the Bacillus subtilis by the experiment example 1, which was the same as the dose and concentration of the spore liquid of Experimental Example 1. Table 1 below shows the average of the results measured by the six-week test.

在上述實驗中,同時發現,由於EM菌及枯草菌所產生菌絲長度較長,容易造成泥水分離槽的堵塞問題,從而需要額外地投入人工撈取、或使投入藥劑來抑制或去除。另外,由放流水化學需氧量的結果來看,EM菌及枯草菌在發酵處理第一生物汙泥時,實質上升高了放流水化學需氧量,需要進一步的控制。因此,根據上述實驗結果,以實驗示例1能維持放流水的化學需氧量、同時減少固態懸浮物為佳。In the above experiment, it was also found that the length of the hyphae produced by the EM bacteria and the Bacillus subtilis was long, which easily caused the clogging problem of the muddy water separation tank, and thus it was necessary to additionally invest in artificial fishing or to put drugs into the inhibition or removal. In addition, from the results of the chemical oxygen demand of the discharged water, the EM bacteria and the Bacillus subtilis substantially increase the chemical oxygen demand of the discharged water when the first biological sludge is fermented, and further control is required. Therefore, according to the above experimental results, it is preferable to maintain the chemical oxygen demand of the discharged water while reducing the solid suspended matter in Experimental Example 1.
在上述的實施例中,選擇光合菌及芽孢菌液以處理有機廢水,並分別以適合的兼氧、好氧環境能夠得到較佳的汙泥減量效果,同時也不會影響放流水的水質。此外,光合菌及芽孢菌液之菌絲也不會過度生長而產生堵塞的問題。可以達到從源頭減少生物汙泥量,減少額外的耗能、藥物添加或是設備成本,而能解決習用技術上的所面臨的問題,更克服的技術偏見。In the above embodiments, the photosynthetic bacteria and the spore liquid are selected to treat the organic wastewater, and a suitable sludge reduction effect can be obtained in a suitable facultative and aerobic environment, respectively, without affecting the water quality of the discharged water. In addition, the hyphae of photosynthetic bacteria and spore liquids do not excessively grow to cause clogging. It can reduce the amount of biological sludge from the source, reduce the additional energy consumption, drug addition or equipment cost, and can solve the problems faced by the conventional technology and overcome the technical bias.
