Description of the invention: [Technical field to which the invention pertains] The present invention relates to a remediation technique for environmental engineering. In particular, the present invention relates to a composition and method for treating contaminants in water using dehydrated biological sludge. [Prior Art]
水中污染物之清除一直是環境保護中重要的課題。在許 多工業區及廢棄物傾倒區，地下水已被過量使用且被隨意 棄置之有機溶劑所污染。於各式有機溶劑中，含氣有機溶 劑危害環境為最，又以四氯乙浠（tetrachloroethylene或 p er chi or 〇 ethylene，PCE)及三氯乙烯（trichloroethylene， TCE)所造成的污染最為普遍且嚴重。由於含氣有機溶劑具 有較高毒性且不易被分解，因此若要以生物分解方式整治 含氯有機溶劑之污染，必須提供其他有機質作為主要基質 (primary substrate)或電子供應者（electron donor)，藉由好 氧共代謝（cometabolism)或厭氧還原脫氣（reductive dechlorination)程序分解去除。目前一些有機質已被提供做 為主要基質（如苯類、醇類、酸類及酚類等有機質），以加強 含氯有機溶劑之生物分解。但是注入這些有機質到水體 中，則又造成二次污染。 再者，依地下水整治技術而言，目前較常用之地下污染 整治技術包括抽取處理法（pump-and-treat)及空氣氣化法 (air sparging)。由於抽取處理法係將地下水抽取至地表，經 整治處理後回注至地下，屬於長期性的整治技術且需要許The removal of pollutants in water has always been an important issue in environmental protection. In many industrial areas and waste dumping areas, groundwater has been over-consumed and contaminated with arbitrarily disposed organic solvents. Among various organic solvents, gas-containing organic solvents are the most harmful to the environment, and pollution caused by tetrachloroethylene or tetrachloroethylene (PCE) and trichloroethylene (TCE) is the most common. serious. Since the gas-containing organic solvent is highly toxic and difficult to be decomposed, in order to biodegrade the pollution of the chlorine-containing organic solvent, other organic matter must be provided as a primary substrate or an electron donor. It is removed by aerobic co-bolism or reductive dechlorination. At present, some organic matter has been provided as the main matrix (such as organic substances such as benzenes, alcohols, acids and phenols) to enhance the biodegradation of chlorine-containing organic solvents. However, injecting these organic matter into the water body causes secondary pollution. Furthermore, according to the groundwater remediation technology, the more commonly used underground pollution remediation technologies include pump-and-treat and air sparging. Because the extraction method is to extract groundwater to the surface, it is re-injected into the ground after remediation, which is a long-term remediation technology and requires

The air gasification method is more suitable for aquifers with high permeability. However, in some water layers with large changes in permeability, air bubbles are easy to form tube flow, reducing the contact area between air and water, resulting in a decrease in pollutant removal efficiency. . In addition, the installation and maintenance of mechanical equipment for introducing air also increases the cost of the air gasification process. This is a development method that can effectively decompose pollution in water, low cost, and does not cause one-person pollution, which is required for environmental engineering.

The dehydrated biological sludge in the composition of the present invention can provide the organic matter necessary for biodegradation as a main matrix or electron supplier to decompose and remove pollutants by aerobic co-metabolism or anaerobic reduction degassing procedure without If the main matrix such as benzene, alcohol, acid and phenol is added by conventional techniques, the pollutants can be smoothly removed. The term "dehydrated biological sludge" as used in this section refers to a composition containing microorganisms and organic matter, but its composition is too complicated to be listed one by one, preferably in a domestic sewage plant. The sludge is dehydrated. The dehydrated biological sludge according to the present invention can provide a microbial species and a main substrate which are required for the biodegradation of pollutants.

On the other hand, the source of dehydrated biological sludge is non-toxic (such as sludge waste from the life π water plant), which is easy to obtain and has the advantages of resource recycling. The proportion of dewatered biological sludge in the composition of the present invention depends on the composition of the dewatered biological sludge and the degree of contamination of the water to be treated. In general, the weight ratio of the dewatered biological sludge to the composition is from 18: 7.5 to 2.1: 8.6. The term "porosity enhancer" as used in the present invention means a component which, when mixed with the dewatered biological sludge according to the present invention, increases the porosity of the whole mixture, and its physical or chemical properties do not interfere with the decomposition of the pollutants treated by the dewatered biological sludge. By increasing the porosity, the water permeability of the composition is increased, and the organic matter release rate of the dehydrated biological sludge is increased, so that the treatment efficiency of the dehydrated biological sludge is improved. Preferably, the pore enhancer according to the present invention preferably comprises sand, wood chips, rice or straw; more preferably contains sand. The proportion of the pore enhancer in the composition of the present invention depends on the nature of the pore enhancer and the degree of contamination of the water to be treated. In general, the weight ratio of the pore enhancer to the composition is from 5:7 to 8·6. The term "cured material" as used in the present invention means that the dehydrated biological sludge according to the present invention can be cured. With the pore enhancer, it becomes a solid component for easy application, and avoids the complete contact of the dehydrated biological sludge with the water body, and the organic matter is rapidly dissolved to consume excessive organic matter. Any suitable compound can be used in the compositions of the present invention. Preferably, the chemical comprises water

Since the amount of water added is extremely low, the majority of the composition will not lose its properties due to the reaction. The composition obtained has a specific gravity of the surface and a lucky one. The organic matter rate (batch reaction) was released from the prepared composition in a 1 liter beaker. It is a combination of (10) grams of two components: T in a cup containing 200 ml of deionized water. The change of ChemiCal oxygen demand (COD) in the water and the replacement of the cup ion 纟 can measure the rate of release of organic matter from the organic compound. The chemical oxygen demand analysis method is the environmental test of the Republic of China. The method announced (NIEA W5 15.53A). The batch-to-human response results are shown in Figure 2. The results show that during the first day, there is a large change in the rate of organic matter release, but after about 50 days, the release rate is gradually stabilized. The linear regression curve of the data (50 days to 100 days) was (mg COD) / day / gram of composition = - 〇〇〇〇 1 >< days + 〇〇 43. The organic matter release rate was between about 0.051 and 037.037 mg C 〇 D per day per gram of composition, and the average release rate was about m.〇43mSCOD/day/gram of composition. Batch reaction experiments have also shown that this composition maintains this stable organic matter release rate for up to three months of release time. Therefore, when the composition is applied to the contaminated site for remediation, the release rate of the organic matter can be gradually reduced after the use of the composition for more than three months, and the remediation cost and labor cost of the contaminated site can be saved. The above-described embodiments are merely illustrative of the principles and effects of the invention and are not intended to limit the invention. Modifications and variations of the embodiments described above will be apparent to those skilled in the art without departing from the spirit of the invention.
