Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of micro-polluted water treatment, and particularly relates to a salt-tolerant bacteria generator for open water surface. BACKGROUND

[0002] As an ecological friendly, low operation cost and good effect micro-polluted water treatment measure, the artificial wetland is widely used in tail water treatment of sewage treatment plants, tail water treatment of aquaculture, non-point source pollution treatment and other fields, but due to the regional characteristic factors, when the sewage is micro-saline water, the conventional microbial agent has poor pollutant reduction effect, and the salt-tolerant bacteria can adapt to the micro-saline water environment and efficiently reduce the pollutants, so the salt-tolerant bacteria are used for treating seawater aquaculture tail water and northern micro-saline water, however, when the salt-tolerant bacteria are scattered on the open water surface, the salt-tolerant bacteria are generally non-native species, and there is a competitive relationship with local species, and the environmental conditions are not suitable and many other factors, so it is difficult for the salt-tolerant bacteria to better play the effect of removing pollutants. SUMMARY

[0003] The technical problem to be solved by the present application is to provide a salt-tolerant bacteria generator for open water surface, so as to overcome the shortcomings of the prior art.

[0004] The technical scheme for solving the above technical problem is as follows: a salt-tolerant bacteria generator for open water surface, comprising: a water-soluble-microbial degradation type container, a biological carrier mixed with salt-tolerant bacteria and growth factors is placed in the closed cavity inside the water-soluble-microbial degradation type container.

[0005] The beneficial effects of the present application are:

[0006] Before the salt-tolerant bacteria generator contacts water, the salt-tolerant bacteria generator is not started;

[0007] When the salt-tolerant bacteria generator is put into the open water surface, the water-soluble material in the water-soluble-microbial degradation type container will start to dissolve when meeting water, so as to form a pore structure on the wall of the water-soluble-microbial degradation type container, and the sewage can flow into the inner cavity through the pore structure and contact the salt-tolerant bacteria and the growth factors, the growth factors will promote the salt-tolerant bacteria to start quickly, so as to carry out decontamination treatment on the sewage, and the salt-tolerant bacteria can also be released through the pore structure and enter the open water surface, and the carbon source can be provided for the salt-tolerant bacteria in the process of dissolving the water-soluble material, so that the salt-tolerant bacteria can continuously grow and reproduce in the cavity, and with the passage of time, the microbial degradation material is also gradually degraded, so as to form more pore structures on the wall of the water-soluble-microbial degradation type container, at this time, the salt-tolerant bacteria also gradually adapt to the environment, and the salt-tolerant bacteria will be gradually released in large quantities, so the decontamination effect can be efficiently played due to the large amount of release;

[0008] The salt-tolerant bacteria generator can provide the salt-tolerant bacteria with suitable growth environment conditions and has a salt-tolerant bacteria slow-release function, so that the salt-tolerant bacteria are gradually released to the polluted water body, and the salt-tolerant bacteria have time and conditions to gradually adapt to the polluted water area, and meanwhile, a long-acting pollutant reduction effect is achieved.

[0009] Based on the above technical solution, the application can be further improved as follows.

[0010] Further, the biological carrier is sprinkled with other synergistic functional bacteria agents, and the other synergistic functional bacteria agents are one or more of nitrifying bacteria, denitrifying bacteria, acinetobacter, pseudomonas, and lactic acid bacteria.

[0011] Further, the raw materials used by the water-soluble-microbial-degradation type container include plant carbon sources, water-soluble polymers, microbial-degradation type polymers, gravel, and cement mortar.

[0012] The above further beneficial effects are as follows: the water-soluble polymers can be dissolved after being contacted with water, so as to form pore structures on the wall of the water-soluble-microbial-degradation type container, and in addition, the water-soluble polymers can provide carbon sources for the salt-tolerant bacteria, which are necessary for the growth of the salt-tolerant bacteria and are difficult to obtain from open water bodies; the microbial-degradation type polymers can be degraded by microorganisms, so as to form more pore structures on the wall of the water-soluble-microbial-degradation type container; and the plant carbon sources can also provide carbon sources for the salt-tolerant bacteria and provide nutrients for the growth and reproduction of the salt-tolerant bacteria; as the plant carbon sources are utilized by microorganisms, the pore structures on the wall of the water-soluble-microbial-degradation type container will become more and more, so that the salt-tolerant bacteria are released in large quantities, thereby achieving a high-efficiency decontamination effect; after the water-soluble polymers, the microbial-degradation type polymers, and the plant carbon sources are used up, the remaining structures can be used again, and the biological carrier with attached salt-tolerant bacteria and growth factors can be reloaded in the cavities of the structures, so that the structures can be used as emergency salt-tolerant bacteria generators, and the structures have good reusability, are green and environmentally friendly, and do not pollute the environment.

[0013] Further, the raw materials used by the water-soluble-microbial-degradation type container have three different proportioning ranges, which are as follows:

[0014] The volume proportion of the plant carbon sources in the water-soluble-microbial-degradation type container is 20% to 30%, and the volume ratio of the water-soluble polymers, the microbial-degradation type polymers, and the plant carbon sources is 1:(1 to 5):(1 to 3);

[0015] Alternatively, the volume proportion of the plant carbon sources in the water-soluble-microbial-degradation type container is 10% to 20%, and the volume ratio of the water-soluble polymers, the microbial-degradation type polymers, and the plant carbon sources is 1:(5 to 15):(3 to 5);

[0016] Or, the volume ratio of the plant carbon source in the water-soluble-microbial degradation type container is 1% to 10%, and the volume ratio of the water-soluble polymer, the microbial degradation type polymer and the plant carbon source is 1:(20 to 50):(5 to 10).

[0017] The further beneficial effect is that by adjusting the carbon release rate of the water-soluble-microbial degradation type container through different combinations of the water-soluble polymer, the microbial degradation type polymer and the plant carbon source, the pore structure on the wall of the water-soluble-microbial degradation type container gradually increases over time, so that the halophilic bacteria can better adapt to the environmental conditions and meet different expected action times.

[0018] Further, the water-soluble polymer is one or both of PVA and PEG; the microbial degradation type polymer is one or more of PBAT, PLA and PCL.

[0019] Further, the plant carbon source is conventional agricultural waste, and the conventional agricultural waste is one or more of peanut shells, corn cobs and straws.

[0020] Further, the number of the water-soluble-microbial degradation type containers is one, and the raw materials used in the water-soluble-microbial degradation type containers are any one of the three different ratio ranges;

[0021] The number of the water-soluble-microbial degradation type containers is two, and the raw materials used in the two water-soluble-microbial degradation type containers are any two of the three different ratio ranges;

[0022] The number of the water-soluble-microbial degradation type containers is three, and the raw materials used in the three water-soluble-microbial degradation type containers correspond to the three different ratio ranges.

[0023] The further beneficial effect is that by stacking multiple halophilic bacteria generators and using different material ratios of the water-soluble-microbial degradation type containers in each halophilic bacteria generator, the time for each layer of the halophilic bacteria generator to work can be controlled, thereby prolonging the service life of the halophilic bacteria generator on the time axis and playing the long-acting mechanism of the halophilic bacteria generator.

[0024] Further, the number of water-soluble-microbial-degradation type containers is two or three, and a through hole is formed in the top and bottom of each water-soluble-microbial-degradation type container; all the water-soluble-microbial-degradation type containers are arranged in sequence from top to bottom, and two adjacent water-soluble-microbial-degradation type containers are connected by a plug, the two ends of the plug being inserted into the through hole in the top of the water-soluble-microbial-degradation type container below and the through hole in the bottom of the water-soluble-microbial-degradation type container above, respectively; the through hole in the bottom of the lowermost water-soluble-microbial-degradation type container is sealed by a plug, and the through hole in the top of the uppermost water-soluble-microbial-degradation type container is sealed by a plug.

[0025] Further, the biological carrier is polyurethane or rope-shaped artificial water grass.

[0026] The above further beneficial effect is that the biological carrier of this type can provide a growth and reproduction space for halophilic bacteria. BRIEF DESCRIPTION OF DRAWINGS

[0033] The principles and features of the present application are described below in conjunction with the drawings, and the examples are only used to explain the present application and are not intended to limit the scope of the present application.

[0034] Example 1

[0035] As Figure 1 , Figure 2As shown, a salt-tolerant bacteria generator for open water surface includes: a water-soluble-microbial-degradable container 1, which is an internally hollow container with no shape limitation, a biological carrier 4 is placed in the sealed cavity inside the water-soluble-microbial-degradable container 1, salt-tolerant bacteria 2 and growth factors 3 are scattered on the biological carrier 4, the growth factors 3 are necessary for the growth of the salt-tolerant bacteria 2 and are difficult to obtain from the open water body, so the addition of the growth factors 3 can serve as a starting resource for the salt-tolerant bacteria 2.

[0036] When the salt-tolerant bacteria generator is put into the open water surface, the water-soluble material in the water-soluble-microbial-degradable container 1 will start to dissolve when it meets water, forming a pore structure on the wall of the water-soluble-microbial-degradable container 1, and sewage can flow into the inner cavity through the pore structure and contact the salt-tolerant bacteria 2 and the growth factors 3, which will promote the rapid start of the salt-tolerant bacteria 2, thereby decontaminating the sewage, and the salt-tolerant bacteria 2 can also be released through the pore structure and enter the open water surface, and the water-soluble material can provide carbon source for the salt-tolerant bacteria 2 during the dissolution process, allowing the salt-tolerant bacteria 2 to continuously grow and reproduce in the cavity, and over time, the microbial degradation material is also gradually degraded to form more pore structures on the wall of the water-soluble-microbial-degradable container 1, at this time, the salt-tolerant bacteria 2 also gradually adapts to the environment, and the salt-tolerant bacteria 2 will gradually be released in large quantities, and due to the large amount of release, it can efficiently decontaminate.

[0037] Example 2

[0038] As shown, this embodiment is a further improvement based on example 1, as follows: Figure 2 The biological carrier 4 is scattered with other synergistic functional bacteria agents, which can be selected according to the main pollutants removal target of the contaminated sewage to expand the treatment range of the sewage, such as one or more of nitrifying bacteria, denitrifying bacteria, acinetobacter, pseudomonas, and lactic acid bacteria.

[0039] Example 3

[0040] As shown, this embodiment is a further improvement based on example 1 or 2, as follows:

[0041] Figure 1

[0042] ​​The raw materials used by the water-soluble-microbial degradation type container 1 include: plant carbon source, water-soluble polymer, microbial degradation type polymer, gravel and cement mortar, that is, the water-soluble-microbial degradation type container 1 is formed by mixing plant carbon source, water-soluble polymer, microbial degradation type polymer, gravel and cement mortar, and can have a rectangular body shape or other shapes, the particle size of the plant carbon source is 3mm-5mm, which can balance the cost and carbon release performance; the particle size of the gravel is 5mm-15mm, which can balance the strength, mixing uniformity and porosity, the water-soluble polymer can be dissolved after being contacted with water, so as to form a pore structure on the wall of the water-soluble-microbial degradation type container 1, in addition, it can also provide carbon source for the halophilic bacteria 2, the carbon source is necessary for the growth of the halophilic bacteria 2 and is difficult to obtain from open water, so the addition of the plant carbon source can supplement the growth of the halophilic bacteria 2, the microbial degradation type polymer can be degraded by microorganisms, so as to form more pore structures on the wall of the water-soluble-microbial degradation type container 1, and the plant carbon source can also provide carbon source for the halophilic bacteria 2 and provide nutrients for the growth and reproduction of the halophilic bacteria 2, as the plant carbon source is utilized by microorganisms, the pore structure on the wall of the water-soluble-microbial degradation type container 1 will become more and more, so that the halophilic bacteria 2 is released in large quantities, thereby playing a high-efficiency decontamination effect, after the water-soluble polymer, the microbial degradation type polymer and the plant carbon source are used up, the remaining structure can be used again, and the biological carrier 4 attached with the halophilic bacteria 2 and the growth factor 3 is reloaded in the cavity thereof, which can be used as an emergency halophilic bacteria generator, has good reusability, is green and environmentally friendly, and has no pollution to the environment.

[0043] In order to make the halophilic bacteria 2 better adapt to the environmental conditions and meet different expected action times, the raw materials used by the water-soluble-microbial degradation type container 1 have three different proportioning ranges, which are:

[0044] ①, the volume proportion of the plant carbon source in the water-soluble-microbial degradation type container 1 is 20%-30%, and the mass ratio of the water-soluble polymer, the microbial degradation type polymer and the plant carbon source is 1:(1-5):(1-3);

[0045] In the proportioning ①, the proportion of the water-soluble polymer is large, which can quickly dissolve to provide carbon source and form a pore structure on the wall of the water-soluble-microbial degradation type container 1, activate the halophilic bacteria 2, and release the halophilic bacteria 2, and the main action time is within 1 month after the halophilic bacteria generator is put, which can quickly react and timely play the halophilic bacteria removal effect;

[0046] ②, the volume proportion of the plant carbon source in the water-soluble-microbial degradation type container 1 is 10%-20%, and the mass ratio of the water-soluble polymer, the microbial degradation type polymer and the plant carbon source is 1:(5-15):(3-5);

[0047] The proportioning 2 properly reduces the proportion of water-soluble polymer, and increases the proportion of microorganism-degradable polymer with better slow-release performance and plant carbon source, so that the pore structure on the wall of the water-soluble-microorganism-degradable container 1 is formed slowly, thereby slowing down the release of the halophilic bacteria 2, and to some extent, making the halophilic bacteria 2 play a good performance, and the main action time is within 2 months to 6 months after the halophilic bacteria generator is put in;

[0048] 3, the volume proportion of the plant carbon source in the water-soluble-microorganism-degradable container 1 is 1% to 10%, and the mass ratio of the water-soluble polymer, the microorganism-degradable polymer and the plant carbon source is 1:(20-50):(5-10);

[0049] The proportioning 3 greatly reduces the proportion of water-soluble polymer, and increases the proportion of microorganism-degradable polymer with better slow-release performance and plant carbon source, thereby greatly improving the overall slow-release performance of the slow-release carbon source, making the pore structure on the wall of the water-soluble-microorganism-degradable container 1 become slower, and the time needed for the opened pore structure to change from few to many is longer, thereby improving the slow-release performance of the halophilic bacteria, and the main action time is within 6 months to 1 year after the halophilic bacteria generator is put in.

[0054] The plant carbon source is conventional agricultural waste, and the conventional agricultural waste can be one or more of peanut shells, corn cobs and straws.

[0058] When option ① is selected, its main function is within one month after the salt-tolerant bacteria generator is deployed, and it can be used as an emergency generation layer.

[0059] When option ② is selected, its main period of action is from the 2nd to the 6th month after the salt-tolerant bacteria generator is put into use, and it can be used as the main generation layer.

[0060] When option ③ is selected, its main effect time is within 6 months to 1 year after the salt-tolerant bacteria generator is put into use, and it can be used as a long-term generation layer.

[0061] The specific choice depends on the actual needs.

[0062] There are two water-soluble-microbial degradable containers 1. The raw materials used in the two water-soluble-microbial degradable containers 1 are any two of three different ratio ranges, such as: ①+② combination, that is, as an emergency generation layer + main generation layer; ①+③ combination, that is, as an emergency generation layer + long-term generation layer; and ②+③ combination, that is, as a main generation layer + long-term generation layer. The specific combination is selected according to the actual needs.

[0063] There are three water-soluble-microbial degradable containers 1.

[0067] All water-soluble-microbial degradable containers 1 are arranged sequentially from top to bottom, and adjacent water-soluble-microbial degradable containers 1 are connected by plugs 5. Specifically, the two ends of the plugs 5 are inserted into the through holes 110 at the top of the lower water-soluble-microbial degradable container 1 and the through holes 110 at the bottom of the upper water-soluble-microbial degradable container 1, respectively, so that adjacent water-soluble-microbial degradable containers 1 are connected. The through hole 110 at the bottom of the lowest water-soluble-microbial degradable container 1 is sealed by the plugs 5.

[0068] The through-hole 110 at the top of the uppermost water-soluble-microbial degradable container 1 is sealed by the plug 5. Of course, this is only one way of connecting. The connecting material is a columnar, non-degradable wooden stick or soft plastic. In actual application, other forms are also possible.
