[Field of Industrial Application] This invention is a sludge treatment method for biologically purifying various organic sludges of plant origin, animal origin, and mixed animal and plant origin, such as sludge from domestic wastewater and sludge from agriculture and livestock farming. Regarding the improvement of [Prior Art] Conventional sludge treatment methods have the disadvantage that a large amount of surplus sludge remains after treatment and that toxic gas is generated during treatment, resulting in a bad odor. In order to overcome this drawback, a method of biologically treating sludge has already been proposed by the present inventors (Japanese Unexamined Patent Application Publication No. 1983-1999).
106595) was done. This treatment method adds a small amount of squeezed juice from Yutsuka, a type of plant in the lily family, during sludge treatment to give vitality to microorganisms in the sludge and speed up their growth. The aim is to promote this. [Problem to be solved by the invention] However, although the Yutsuka used in the above treatment method is mainly produced in southern North America and the West German Islands, and is collected from the wild, the uses of Yutsuka are limited. Therefore, there is a problem that there is no mass production system, and therefore the cost of raw materials is high and it is difficult to obtain them. In view of these points, the present invention aims to provide a sludge treatment method that can be expected to have the same effects as Yutsuka, using materials that are inexpensive and easily available. [Means for solving the problem] The technical means of the sludge treatment method of the present invention is to add aloe undiluted solution to organic sludge in a diluted state with water, and to adjust the amount of addition. The objective is to set the amount of aloe vera to 0.0001% or more and 0.1% or less, based on the amount of sludge to be treated, in terms of aloe concentrate. Aloe (ALOE) used in the present invention is a succulent plant of the Liliaceae family, and is mainly produced in Africa and Central America, including Socotra Aloe, Cape Aloe,
Typical examples include Aloe vera and Aloe vera.
There are over 200 types. This aloe vera is widely used as a medicine as specified in the pharmacopoeia, and recently it has also been used in foods and cosmetics. In this way, aloe vera has a wide range of uses and is used in large quantities, so in addition to collecting it from the wild,
It is also cultivated artificially, has a mass production system, is cheap, and is easily available. This aloe is generally provided in a solid state by pressing fresh leaves to extract the juice, which is then heated to dryness. The scientific components of aloe juice have not yet been completely elucidated, and in addition to several types of polysaccharides,
It is only known that it contains trace components such as uronic acid, lipoids, and saponin. In the present invention, the aloe stock solution refers to pressed aloe juice or solid aloe redissolved to the concentration of squeezed juice. Since it is difficult to obtain aloe juice in its pure form, solid aloe is usually redissolved before use. When pressed aloe juice is heated to dryness, its weight becomes approximately 1/100th, so when dissolving solid aloe, do the opposite by dissolving the aloe in 100 times its weight of water, and then add this to the aloe undiluted solution. shall be. In the present invention, the amount of aloe undiluted solution added is 0.0001% or more and 0.1% or less based on the amount of sludge in terms of the undiluted solution. If it is less than 0.0001%, no effect will be seen.
Even if 0.1% or more is added, the effect remains unchanged and it is useless. According to the experimental results, the amount of aloe added
It has been found that 0.005 to 0.05% is the most effective and economical. Note that the optimum value for the amount added varies depending on the type of sludge, so in actual use, it is preferable to increase or decrease the amount added depending on the type of sludge to be treated. In the present invention, aloe is added in such a way that the aloe undiluted solution is diluted with water. That is,
When adding aloe, do not let it act on the sludge at the undiluted concentration, but make sure to let it act on the sludge at a diluted concentration. For this reason, dilute the aloe undiluted solution with water before addition, or add the undiluted solution only if the sludge to be treated contains sufficient water, so that it will be in a diluted state after addition. Make it. Normally, it is appropriate to dilute the aloe vera stock solution 100 to 1000 times. [Function] In the sludge treatment method of the present invention, aloe is added to sludge. The detailed reason for the effect of aloe on sludge after addition is unknown, but the special compounds contained in aloe act on microorganisms in the sludge, and this is coupled with the action of the surfactant substances contained in aloe. It is presumed that this increases the vitality of microorganisms, accelerates their proliferation, and promotes the biological decomposition of sludge. In fact, when aloe is added to sludge, microorganisms in the sludge begin to proliferate within 1 to 2 days, and after 10 to 20 days, the microorganisms have multiplied several times to more than 10 times. In addition, gas generation increases, and the components of the generated gas include many beneficial gases such as methane and less malignant gases such as hydrogen sulfide and mercabutane, resulting in extremely low odor of the generated gas. Furthermore, the decomposition of sludge is promoted, and the amount of excess sludge that ultimately remains after treatment is greatly reduced. The effects of aloe as described above occur regardless of the treatment conditions if the sludge is organic. Therefore, the present invention can be widely used for biological treatment of organic sludge. [Example] Examples in which the sludge treatment method of the present invention was applied to food industry waste liquid and sewage sludge will be described below. In addition, the following abbreviations were used in the examples. COD: Chemical oxygen demand VTS: Volume of volatile components in sludge (MLVSS) TS: Total amount of suspended solids MLSS: Total amount of activated sludge Example 1 Conducted on mandarin orange waste liquid. That is, aloe was added to mandarin orange waste liquid, and the effect under anaerobic conditions was compared with that without the addition. Tank capacity: 4 Operating temperature: 20℃ Stirring conditions: once a day, low speed stirring Base solution: Mandarin orange waste COD approx. 16000mg / Pectin approx. 10000mg / VTS approx. 40000mg / Amount of aloe stock solution added: 100mg / Acclimatization period: 10 days data Collection: Days 11-20

[Table] The VTS value was initially 40,000 mg/20 days later, it was 34,800 mg/ without aloe, while it was 30,200 mg/ with aloe added.
The decrease in VTS value when aloe was added was greater than when it was not added, confirming the effect of aloe addition. In addition, there was a terrible odor when no additive was added, but almost no odor was produced when aloe was added. Example 2 Aloe was added to tangerine waste liquid under the following conditions, and the amount of gas generated in an anaerobic state was compared with that without the addition. Base solution: Mandarin orange waste organic matter load: 2.8 to 3.2 Kg/m 3 / Daily temperature: 38°C Amount of aloe stock solution added: (1) 50 mg/ (2) 100 mg/ The results are shown in the graph of Figure 1. It was confirmed that from around the second day after adding aloe vera, the amount of gas generated increased significantly compared to when no additive was added. Moreover, when aloe was added, there was no bad odor. Example 3 This was carried out on surplus sludge from sewage. That is, aloe was added to excess sludge, and the amount of gas generated under anaerobic conditions was compared with that without the addition. Base solution: Surplus sludge at the end of sewage Organic matter load: 1.4 to 1.8 Kg/m 3. Daily temperature: 20℃ TS: Approx. 15000 mg/ Amount of aloe stock solution added: (1) 50 mg/ (2) 150 mg/ The results are shown in the graph in Figure 2 is shown. When aloe was added, the amount of gas generated increased significantly compared to when it was not added. Moreover, this generated gas had no bad odor. Example 4 Conducted in a sewage treatment facility. The initial amount of sludge input
The sludge was 10 m 3 and new sludge was added by 3 m 3 every 10 days. In addition, 1.0 of aloe was added at the beginning, and 0.3 was added each time new sludge was added, and the treatment was performed in an anaerobic state. The status of sludge input is shown in Table 3.

In the sludge treatment method of the present invention, the vitality of microorganisms in sludge is increased and their proliferation is accelerated, thereby promoting sludge treatment. As a result, the treatment time is shortened, the amount of surplus sludge that ultimately remains is significantly reduced, the effort of dumping is reduced, the treatment tank is easier to manage, and the tank is smaller than before. Sludge can be treated with this equipment. Further, in the present invention, gas generation during treatment increases, and since this gas hardly contains toxic malodorous gases such as hydrogen sulfide, no odor is generated during treatment. Furthermore, the present invention is effective for organic sludge regardless of treatment conditions, so it has a wide range of applications and is extremely useful in practice. Furthermore, since aloe is used in the present invention, it is cheaper and more easily available than the conventional use of Yutsuka, and processing costs can be reduced. Furthermore, since aloe is a material specified in the pharmacopoeia and only a very small amount is used, there is no risk of causing pollution.
