Description

FIELD OF THE INVENTION

The present invention relates to the field of wastewater treatment, in particular, to an effective multifunctional strain agent for activating microorganisms in sewage and its use in wastewater treatment.

BACKGROUND OF THE INVENTION

Currently, most strains used for biochemical treatment of sewage water are cultured and inoculated externally strains.

Existing inoculated externally strains are an active sludge from a wastewater treatment plant with a moisture content above 99% and a relatively small number of effective strains. Each inoculation requires a large number of strains of active sediment, which makes transportation difficult. Such strains of active sludge are also strictly controlled waste, which means that they are difficult to control and manage them in an environmental respect. In the process of culturing and inoculating strains of active sludge, problems arise, consisting in a large amount of dead sludge and floating sludge. Therefore, inoculation of the biochemical system reveals disadvantages consisting in a very complex cultivation, inconvenience of control, very difficult cleaning, etc.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide an effective multifunctional strain means for activating microorganisms in sewage and its use in wastewater treatment.

The technical solution provided by the present invention is an effective multifunctional strain agent for activating microorganisms in sewage waters, the microorganisms of which are cultivated by fermentation using protein-enriched culture medium from kitchen waste at a temperature adjusted to 50-60ºC, during the fermentation period from 7 to 10 days to obtain a large number of microbial strains with a small number of metabolites, followed by further dehydration processes, rivanj, grinding, drawing and packaging for microorganisms present in the rest condition after dehydration, thereby preparing a multifunctional of strains of effective means for activating the microorganisms in sewage waters.

Preferably, in solid substances of kitchen waste, proteins are brought to an amount of more than 60%, plants to not more than 25% and other substances to not more than 15%; the mixture is homogenized, water is added and mixed until homogeneous, bringing the moisture content to 75% - 85% and pH 6-8, thereby obtaining a culture medium from kitchen waste.

Preferably, in solid substances of kitchen waste, the amount of protein is adjusted to 60% - 80%, plants to 10% - 25% and other substances to 5% - 15%.

Preferably, the proteins include unused meat, fish, shrimp and the like, as well as other discarded protein containing substances.

Preferably, the plants include mainly vegetables, and if their content is not sufficient, it can be appropriately supplemented with fiber-rich substances such as leaves and herbs.

Preferably, other substances include bone, calcium, sand, and other small solid substances that are swellable.

Preferably, 0.5% to 1% additives are added to the culture medium from the kitchen waste, the additives including crushed clay, flour, rice bran, and the like.

Preferably, during microbial fermentation, additional strains are added to activate microorganisms, including 35% - 70% of bacilli, 8% - 35% of yeast, 10% - 35% of lactic acid bacteria and 5% - 15% of mold.

Preferably, the fermentation products are dehydrated to a moisture content of 60% to 80%, while the dehydration is carried out using a filter press, and squeezing using a frame plate filter press.

Preferably, the fermentation products are dehydrated by squeezing to a moisture content of 70% to 75%.

Preferably, the dehydrated fermentation products are then transferred to an evaporator to evaporate water at a temperature adjusted to 50-60 ° C, dehydrated to such an extent that the moisture content of the starting product is brought to 40-45%.

The dehydration step is to further remove moisture, which is difficult to remove by mechanical dehydration, by evaporation. The temperature is optimally adjusted to 50-60ºC. If the temperature is too high, the strains can easily die, and if the temperature is too low, the evaporation efficiency will be reduced, and it will take more time, which can lead to a further extension of the fermentation and increase by-products. Dehydration is carried out to such an extent that the moisture content in the initial product is brought up to 40-45% to ensure that the pore water content in microorganisms is close to zero. At this point, breeding microorganisms enter a dormant state due to lack of moisture. After grinding, packaging, drying and storage, they are ready for use, thus obtaining effective multifunctional strains for activating microorganisms in sewage.

The beneficial effects of the present invention include the following.

The present invention relates to strains for activating microorganisms that are able to quickly cultivate and inoculate in a biochemical system for treating sewage water (waste) and improve the efficiency of treating ammonia nitrogen in wastewater. The present invention modifies the traditional method of cultivating microorganisms in a biochemical system for treating sewage water (waste), which requires the addition of an active precipitate to inoculate the strains for microbial cultivation. In accordance with the present invention, it is required to add only a small amount of strain means for activating microorganisms, obtained by the method in accordance with the present invention, in the biochemical system for treating sewage water (waste), which is necessary for the good cultivation and cultivation of microorganisms in the biochemical system for treating sewage water (waste) )

In accordance with the present invention, a powdery product is obtained by using discarded proteins (kitchen waste, unused fish and shrimp, and other discarded protein-containing substances) and a small amount of additives during a series of production processes, such as fermentation, dehydration, evaporation, grinding, formulation and packaging, after which the product is convenient to store, transport and use.

The microorganism activating strain according to the present invention is used for the cultivation of sludge in a biochemical system, which changes the method of sludge cultivation in a biochemical system. As a rule, a sufficient amount of viable microbial flora can be obtained for inoculation in the biochemical system by adding flora continuously for 1-2 weeks in an added portion of 5-10 g / m ^{3 of} waste water, which can further increase the growth rate of the microbial flora, and also improve the intensity and efficiency of the biochemical system for the decomposition of organics in wastewater.

Using the strains in accordance with the present invention for the decomposition of ammonia nitrogen in the biochemical system, as a rule, it is only necessary to continuously add the strains for 1-2 weeks in the added portion of 3-10 g / m ^{3 of} waste water to double the nitrobacteria in the biochemical system, which further increases the rate of the nitrification reaction and the efficiency of the decomposition of ammonia nitrogen in wastewater, thereby achieving the goal of the actual decomposition of ammonia nitrogen in wastewater.

Detailed disclosure of the present invention

The present invention will now be described below in combination with specific examples without limitation.

Example 1

Several tons of kitchen waste (including unused fish, shrimp, and other discarded protein-containing substances) were collected, pre-sorted to remove non-food waste, and drained.

The amount of protein in kitchen waste was brought up to 65%, which was mainly unused meat, fish, shrimp, etc. Plants were brought up to 20%, which was mainly vegetables, respectively supplemented with fiber-rich substances such as leaves and herbs; other substances, such as bones, calcium, sand and other small solid materials, were brought up to 15%. Kitchen waste was drained, homogenized, and 0.5% ground clay and 0.5% flour were added; then water was added, the mixture was stirred until homogeneous, and the moisture content was adjusted to 80% and a pH of 6-8, thereby obtaining a culture medium from kitchen waste.

0.3% (by weight) strains were added to activate microorganisms, including 55% of bacilli, 15% of yeast, 20% of lactic acid bacteria and 10% of mold fungi as a percentage by weight, from kitchen waste, while the bacilli represent an equal mass mixture of Bacillus subtilis, Bacillus natto, Bacillus licheniformis and Bacillus cereus; yeast is an equal mass mixture of Saccharomyces cerevisiae, Candida utilis, Candida tropicalis and Candida lipolytica; lactic acid bacteria are an equal mass mixture of Pediococcus acidilactici, Lactobacillus plantarum, Lactobacillus casei, Streptococcus faecalis and Pediococcus pentosaceus; and molds selected from Aspergillus.

Then the materials were transferred to the production process. The whole production process was carried out on a production line, while the raw materials used according to the scheme were transported in batches and in the required quantities to a fermentation tank after raising the temperature of the raw materials to 50-60ºC by passing through a production conveyor belt with a lower end equipped with a heat exchanger, which was used for heating raw materials.

We used a thermostatically controlled fermentation tank for fermentation at a temperature brought to 50-60ºC to decompose proteins and break down organics into a large amount of humus so that a large number of microbial bacilli and various enzymes could carry out various microbial catalytic reactions. The fermentation time was adjusted to 7-10 days, and the fermentation could be stopped without waiting for the completion of fermentation of raw materials. During this process, most of the microorganisms grew and multiplied, and not many metabolites were obtained.

Fermentation products (which already contained a large number of microbial strains) were pre-dehydrated by squeezing to a moisture content of 75%, and then transferred to an evaporator for evaporation, while the temperature during evaporation was brought to 50-60ºC, while the temperature should not be too high so that the strains do not die. Dehydration was carried out to such an extent that the moisture content in the initial product was adjusted to 40-45% to ensure that the pore water content in microorganisms is close to zero. At this point, breeding microorganisms entered a dormant state due to lack of moisture. After grinding, packaging, drying and dry storage, they were ready for use, thus obtaining effective multifunctional strains for activating microorganisms in sewage waters.

The strains mentioned above for activating microorganisms were used to treat sewage water and compared with strains added from the outside to activate sludge. The results are presented in table 1.

The results of microscopic examination after one week of cultivation are shown in FIG. 1. In FIG. 1A shows that after one week of cultivation, by adding a strain of microorganism activating agent according to the present invention, a significant number of Metazoa appears; whereas in FIG. 1B shows that after one week of cultivation by adding a precipitate, only a small number of Metazoa appear. The results of the installation after two weeks of cultivation are shown in FIG. 2. In FIG. 2A shows that after two weeks of culturing with the strain activating agent for microorganisms in accordance with the present invention, a large amount of sediment adheres to the soft insert. A large amount of sediment represents a wide variety of strains. Typically, a large amount of sludge in wastewater obviously indicates that the strains are numerous. In FIG. 2B shows that after two weeks of culturing by the addition of sediment, a small amount of sediment adheres to the soft insert. It is assumed that the amount of sediment in FIG. 2A is 50% to 80% more than the precipitate in FIG. 2B.

Example 2

Several tons of kitchen waste was collected, pre-sorted to remove non-food waste, and drained.

In solid substances of kitchen waste, the amount of protein was brought up to 70%, plants, such as herbs, were brought up to 20%, and other substances, such as bones, calcium, sand and other small solid materials, were brought up to 10%. Kitchen waste was drained, homogenized, and 1% crushed clay was added, then water was added, the mixture was mixed until homogeneous, and the moisture content was adjusted to 80% and pH 6-8, thereby obtaining a culture medium from kitchen waste.

0.3% (by weight) bacteria were added to activate microorganisms, including 40% bacilli, 30% yeast, 15% lactic acid bacteria and 15% mold fungi as a percentage by weight, into the culture medium from kitchen waste, while the bacilli are an equal mass mixture of Bacillus subtilis, Bacillus natto, Bacillus licheniformis and Bacillus cereus; yeast is an equal mass mixture of Saccharomyces cerevisiae, Candida utilis, Candida tropicalis and Candida lipolytica; lactic acid bacteria are an equal mass mixture of Pediococcus acidilactici, Lactobacillus plantarum, Lactobacillus casei, Streptococcus faecalis and Pediococcus pentosaceus; and molds selected from Aspergillus.

Then the materials were transferred to the production process. The entire production process was carried out on the production line, while the raw materials used according to the scheme were transported in batches and in the required quantities to the fermentation tank after raising the temperature of the raw materials to 55ºC by passing through a production conveyor belt with a lower end equipped with a heat exchanger, which was used for heating raw materials.

We used a thermostatically controlled fermentation tank for fermentation at a temperature of 55 ° C to decompose proteins and break down organics into a large amount of humus so that a large number of microbial bacilli and various enzymes could carry out various microbial catalytic reactions. The fermentation time was adjusted to 8 days, and the fermentation could be stopped without waiting for the completion of the fermentation of raw materials. During this process, most of the microorganisms grew and multiplied, and not many metabolites were obtained.

The fermentation products were pre-dehydrated by compression to reduce the moisture content from more than 90% to 75% by using mechanized pressure filtration. Then the products were transferred to the evaporator for evaporation, while the temperature during evaporation was brought to 55ºC. Dehydration was carried out to such an extent that the moisture content in the initial product was adjusted to 40-45% to ensure that the pore water content in microorganisms is close to zero. At this point, breeding microorganisms entered a dormant state due to lack of moisture. After grinding, packaging, drying and dry storage, they were ready for use, thus obtaining effective multifunctional strains for activating microorganisms in sewage waters.

Example 3

Several tons of kitchen waste was collected, pre-sorted to remove non-food waste, and drained.

In solid substances of kitchen waste, the amount of protein was brought up to 80%, plants were brought up to no more than 15%, other substances, including bone, calcium, sand and other small solid substances, were brought up to no more than 5%. Kitchen waste was drained, homogenized, and 1% rice bran was added, and then water was added, the mixture was mixed until homogeneous and the moisture content was adjusted to 80% and pH 7, thus obtaining a culture medium from kitchen waste.

0.2% (by weight) strains were added to activate microorganisms, including 50% bacilli, 18% yeast, 22% lactic acid bacteria and 10% mold fungi in percentage by weight, into the culture medium from kitchen waste, while the bacilli are an equal mass mixture of Bacillus subtilis, Bacillus natto, Bacillus licheniformis and Bacillus cereus; yeast is an equal mass mixture of Saccharomyces cerevisiae, Candida utilis, Candida tropicalis and Candida lipolytica; lactic acid bacteria are an equal mass mixture of Pediococcus acidilactici, Lactobacillus plantarum, Lactobacillus casei, Streptococcus faecalis and Pediococcus pentosaceus; and molds selected from Aspergillus.

Then the materials were transferred to the production process. The whole production process was carried out on a production line, while the raw materials used according to the scheme were transported in batches and in the required quantities to a fermentation tank after raising the temperature of the raw materials to 50-60ºC by passing through a production conveyor belt with a lower end equipped with a heat exchanger, which was used for heating raw materials.

A thermostatically controlled fermentation tank was used for fermentation at a temperature adjusted to 50-60 ° C for the decomposition of proteins and the destruction of organics into a large amount of humus so that a large number of microbial bacilli and various enzymes could carry out various microbial catalytic reactions. The fermentation time was adjusted to 7-10 days, and the fermentation could be stopped without waiting for the completion of fermentation of raw materials. During this process, most of the microorganisms grew and multiplied, and many metabolites were not obtained.

The fermentation products were pre-dehydrated by compression to reduce the moisture content from more than 90% to 75% by applying mechanized filtration under pressure, and then the products were transferred to an evaporator for evaporation, while the temperature during evaporation was brought to 58 ° C. Dehydration was carried out to such an extent that the moisture content in the initial product was adjusted to 40-45% to ensure that the pore water content in microorganisms is close to zero. At this point, breeding microorganisms entered a dormant state due to lack of moisture. After grinding, packaging, drying and dry storage, an effective multifunctional strain agent for activating microorganisms in sewage waters was obtained.

Comparative Example 1

The conditions were the same as in example 1, except that in the kitchen waste the amount of protein was brought up to 50%, plants were brought up to 30% and other substances were brought up to 20%.

Due to the relatively low proportion of proteins in the culture medium, there were few effective strains. At the same time, due to the rapid decomposition during the fermentation, a large number of metabolites formed, the shelf life of the final product was short, and harmful microorganisms easily grew, destroying the original strains.

Reference Example 2

The conditions were the same as in example 1, except that the fermentation time was adjusted to 12 days and the fermentation was stopped after complete fermentation of the raw material.

As a result, the number of effective strains decreased and the effect was not good. At the same time, after the completion of fermentation, the number of beneficial microorganisms, such as bacilli, decreased significantly; while the number of metabolites increased, and the number of effective components decreased.

Reference Example 3

The conditions were the same as in example 1, except that the moisture content of the starting product was controlled at 35%.

Too high or too low moisture content will affect the preservation of the strain agent for activation and the protection of microorganisms in the strain agent. Too high a moisture content can easily cause microorganisms to multiply and lose their effectiveness, while too low a moisture content can easily lead to death and, thus, to the loss of effective components of the strain agent due to dehydration and dehydration.

With an effective multifunctional strain tool for activating microorganisms in sewage water obtained in accordance with the present invention, practical operations were carried out.
