Description

Microbial cultivation module of wastewater treatment system

The present invention relates to the technical field of a wastewater treatment system, in particular to a microbial cultivation module of the wastewater treatment system.

Since waste paper recycled paper can effectively use resources and protect the ecological environment, more and more attention has been paid. However, in order to separate the fibers in the waste paper from each other and the ink from the fibers, it is necessary to invest a lot of chemicals and use a lot of water, so waste paper and papermaking also produce a lot of waste water.

Waste paper and papermaking wastewater treatment methods include coagulation sedimentation method, biochemical treatment method and chemical treatment method. Among them, the biochemical treatment method uses microorganisms, such as anaerobic bacteria or aerobic bacteria, to carry out biological decomposition. A good living environment for fungi can improve the effect of biodegradation; however, the environment where fungi live is related to wastewater temperature habits. The general wastewater treatment tank cannot effectively reduce the water temperature. Instead, various agents are added in the treatment process to increase the efficiency of biodegradation. The water cleanliness cannot be improved and meet the inspection standards.

Please refer to Figures 1 and 2, the wastewater treatment system generally has a drip filter 10, and a plurality of cultured wooden strips 12 are stacked horizontally inside the drip filter 10, and the cultured wooden strips 12 are used for the implantation and growth of microorganisms. A sprinkler assembly 14 is arranged above the trickling filter 10 to output waste water, and the waste water falls into the trickling filter 10. In this way, the waste water can slide down along the horizontally stacked plural cultured wooden strips 12.

Since each of the cultured wooden strips 12 forms a structure that is squeezed and stacked up and down, the ventilation between the cultured wooden strips 12 is not good and the surrounding has a relatively high temperature, which is not a good growth environment for the growth of microorganisms, and Under such environmental conditions, the activity of microorganisms will be reduced, and naturally the wastewater cannot be effectively biodegraded.

Secondly, each of the cultured wooden strips 12 forms a structure of squeezing and stacking up and down, so that when the cultured wooden strips 12 are to be replaced, all the cultured wooden strips 12 are moved out one by one, so the replacement process is inconvenient and time-consuming.

The object of the present invention is to provide a microbial culture module of a wastewater treatment system, which has the ability to improve the air permeability between the cultured wooden strips and have a lower temperature around, so that the waste water can be improved when passing through the cultured wooden strips. The amount of dissolved oxygen, so that the microorganisms attached to the cultured wooden strips and the microorganisms in the wastewater can obtain a better living environment, thereby improving the activity and survival rate of the microorganisms, thereby improving the cleanliness of the wastewater after treatment and reducing odor.

In order to achieve the above-mentioned purposes and effects, the microbial culture module of the wastewater treatment system disclosed in this embodiment includes a cage with an accommodating space, and the bottom surface of the accommodating space is provided with a plurality of perforations; In the accommodating space of the cage, the cultured wooden strip has a long direction, and the cultured wooden strip is accommodated in the accommodating space, and one end of the long-direction of the cultured wooden strip points to the bottom of the accommodating space; The waste water sprinkled by the sprinkler assembly falls on the surface of each cultured wooden strip inside the cage, and the waste water slides down along the long direction of the cultured wooden strip to the bottom surface of the cage to pass through the perforation. Among them, the cultivated wood stick is red cedar.

In accordance with the objectives and effects of the present invention, a preferred embodiment is presented below, and the component structure and combination form of this embodiment are described in detail in conjunction with the drawings.

Please refer to FIGS. 3, 4, and 5, which reveal that the microbial culture module includes a cage 20 and a plurality of cultured wooden bars 30. The cage 20 has an accommodation space 22, and the bottom surface of the accommodation space 22 has a plurality of perforations 24. The cultured wooden strips 30 are red cedar and have a long direction, and each of the cultured wooden strips 30 is accommodated in the accommodating space 22 of the cage 20. It is worth noting that the long end of the culture wooden strip 30 points to the bottom of the accommodating space 22. Secondly, there is at least one lifting lug 26 on the periphery of the top surface of the cage 20. The figure reveals that this embodiment has a plurality of lifting lugs 26.

Please refer to Figures 6 and 7, the microbial culture module disclosed in this embodiment is used to accommodate the inside of a drop filter 40, and the cage 20 and the culture wooden strip 30 correspond to a sprinkler assembly 42 Below. Therefore, the waste water output by the sprinkler assembly 42 falls on the surface of each cultured wooden strip 30 inside the cage 20, and the waste water can slide down to the bottom surface of the cage 30 along the length of the cultured wooden strip 30 , And then fall out of the perforation 24 to an aeration tank 44.

It is worth noting that the waste water can slide down along the length of each cultured wooden strip 30, and each cultured wooden strip 30 is arranged longitudinally with respect to the cage 20, so that each cultured wooden strip 30 does not form a state of up and down squeezing. The air permeability between the cultured wooden strips 30 is high and the surrounding temperature is relatively low. At the same time, the wastewater can increase the amount of dissolved oxygen when passing through, so that the microorganisms attached to the cultured wooden strips 30 and the microorganisms in the wastewater can obtain better A good living environment can improve the activity and survival rate of microorganisms, thereby improving the cleanliness of wastewater after treatment and reducing odors.

Please refer to Figure 6 again. In this embodiment, the trickling filter 40 contains a plurality of microbial culture modules. Therefore, when replacing the microbial culture modules, a suitable suspension device can be used to combine with the cage 20. The lifting ear 26 on the upper part, and the cage body 20 is lifted out of the trickling filter 40 to replace the culture bar 30, so that the entire replacement process can be more convenient and faster

According to the disclosure and teachings of the above description, the embodiment of the present invention has the length direction of each cultured wooden strip 30 inserted in the accommodating space 22 in a form corresponding to the depth direction of the cage 20, so that each cultured wooden strip 30 It does not form a form of squeezing and stacking up and down, thereby improving the activity and survival rate of microorganisms; secondly, the microorganism culture modules formed by the cultured wooden strips 30 and the cage 20 have the effect of convenient and rapid replacement.

The above-mentioned embodiments are only illustrative of the technology and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with this technology can modify and change the above-mentioned embodiments without violating the technical principle and spirit of the present invention. Therefore, the protection scope of the present invention should be listed in the scope of patent application described later .
