Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to a sewage step-by-step treatment device. Background Art

[0002] Wastewater, especially industrial wastewater, contains a large number of pollutants, including organic and inorganic pollutants. Therefore, wastewater can only be recycled after environmental treatment. Microbial degradation is widely used in wastewater treatment due to its high efficiency and environmentally friendly process.

[0003] Microbial treatment of sewage, such as the use of photosynthetic bacteria, can not only degrade a large number of pollutants in the sewage, but also increase the cleanliness of the sewage after treatment.

[0004] However, the drawbacks of microbial treatment are that, with the continuous treatment of microorganisms and their massive reproduction during the treatment process, the treatment efficiency of microorganisms decreases in the later stages of treatment. This is reflected in the fact that after the microbial reproduction increases, the "growth space" between microorganisms is limited, resulting in a decrease in the microbial reproduction rate, which in turn leads to a decrease in the sewage treatment rate. Current sewage treatment tanks, due to their single tank structure, are unable to continuously pump the treated liquid into an idle environment and provide sufficient reproduction space to ensure efficient sewage treatment. Utility Model Content

[0005] Based on the above background, the purpose of this utility model is to provide a sewage step-by-step treatment device.

[0006] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0039] Example 1

[0040] like Figure 1-4 As shown, a sewage step-by-step treatment device includes a microbial degradation cylinder 1 made of a transparent material (specifically, glass or transparent plastic, and a supporting bracket such as a supporting leg is installed at the bottom of the microbial degradation cylinder 1 in a conventional manner disclosed in the prior art). A partition grid 11 is fixedly connected to the microbial degradation cylinder 1 (specifically, the partition grid 11 is hexagonal in shape). The partition grid 11 divides the microbial degradation cylinder 1 into a plurality of independently arranged degradation chambers A; specifically, the chambers are divided into six independent degradation chambers A, namely a first degradation chamber, a second degradation chamber, a third degradation chamber, a fourth degradation chamber, a fifth degradation chamber, and a sixth degradation chamber.

[0041] The bottoms of the first degradation chamber and the second degradation chamber are connected through a connecting pipe structure, the bottoms of the second degradation chamber and the third degradation chamber are connected through a connecting pipe structure; the bottoms of the third degradation chamber and the fourth degradation chamber are connected through a connecting pipe structure; the bottoms of the fourth degradation chamber and the fifth degradation chamber are connected through a connecting pipe structure; and the bottoms of the fifth degradation chamber and the sixth degradation chamber are connected through a connecting pipe structure.

[0042] Specifically, the connecting pipe structure includes a U-shaped connecting pipe 4 , and a valve is installed on the U-shaped connecting pipe 4 .

[0043] At the same time, according to the conventional pumping method disclosed in the prior art, a material pipe (not shown) is connected to the bottom of each degradation chamber A (i.e. the first to sixth degradation chambers) for pumping various types of sewage.

[0044] During the decomposition process, sewage and photosynthetic bacteria liquid are first pumped into the mixing chamber from the feed pipe at the bottom of the first degradation chamber, and then the sewage is degraded in the first degradation chamber by photosynthetic bacteria. As the degradation treatment time increases, the number of photosynthetic bacteria increases. At this time, the mixed system formed by the sewage and photosynthetic bacteria system in the first degradation chamber is pumped into the second degradation chamber. The specific pumping amount is preferably half of the pumping amount. Subsequently, sewage is continuously pumped into the first and second degradation chambers. Subsequently, the sewage and photosynthetic bacteria system in the second degradation chamber form a mixed system that is partially pumped into the third degradation chamber. This is repeated to achieve continuous replenishment of sewage during the decomposition process and continuous dilution of the sewage after decomposition. After dilution, the reproduction space of microorganisms increases, and the efficiency of its sewage degradation is maintained at a high state. In this way, the sewage and microbial system are continuously separated and graded, increasing the sewage degradation space for microorganisms and the reproduction space for microorganisms during the degradation process.

[0045] In order to realize the pumping of sewage between different degradation chambers, the sewage stage-by-stage treatment device further includes a plurality of material pumping and discharging mechanisms corresponding to the degradation chambers. The material pumping and discharging mechanisms include a push plug 31 corresponding to the shape of the degradation chamber A (specifically, the shape of the push plug 31 corresponding to the shape of the degradation chamber is fan-shaped). The top of the push plug 31 is fixedly connected to a pushing hydraulic cylinder 32. The specific method is as follows:

[0046] The plunger rod of the hydraulic cylinder 32 is fixedly connected to the push rod 321 ; the bottom of the push rod 321 is fixedly connected to the mounting seat 3211 , and the mounting seat 3211 is fastened to the top of the push plug 31 by a plurality of bolts.

[0047] During operation, if the first degradation chamber pumps sewage into the second degradation chamber, the vent pipe 311 of the push plug 31 on the second degradation chamber is opened (each push plug 31 is equipped with a vent pipe, and a valve is installed on the vent pipe). At this time, the valve on the connecting pipe structure is opened. At this time, the push plug 31 on the first degradation chamber is pushed downward by the hydraulic cylinder 32 and pushes the sewage system into the second degradation chamber.

[0048] By means of the above method, during the process of transferring sewage and bacterial system, the bacteria that degrade sewage in different degradation chambers always maintain the optimal bacterial quantity due to sufficient breeding space, thereby greatly improving the sewage degradation effect.

[0049] The top of the cylinder barrel of the above-mentioned pushing hydraulic cylinder 32 is fixedly connected to the hydraulic cylinder fixing frame 33 (the top of the cylinder barrel of the pushing hydraulic cylinder 32 and the hydraulic cylinder fixing frame 33 are fixed by fastening bolts), and the lower end of the hydraulic cylinder fixing frame 33 is fixedly installed on the outer wall of the microbial degradation cylinder 1.

[0050] Example 2

[0051] like Figure 1-4 As shown, based on the structure of Example 1, in order to achieve sufficient light required for the growth of photosynthetic bacteria during the microbial degradation process, the outer side of the above-mentioned microbial degradation cylinder 1 is assembled and connected with an illumination mechanism. The illumination mechanism includes an annular light rod rack 21 fixedly connected to the microbial degradation cylinder 1, and the annular light rod rack 21 is arranged at intervals up and down (the lower end of the hydraulic cylinder fixing frame 33 and the annular light rod rack 21 located at the upper end are fixedly connected by connecting bolts). At the same time, the same as the existing lighting method for cultivating photosynthetic bacteria, a number of lighting lamp sticks 22 are installed between the above-mentioned annular light rod racks 21. The lighting lamp sticks 22 are lighting lamp sticks used for the cultivation of existing photosynthetic bacteria, and are used to increase the light energy.

[0052] At the same time, the illumination mechanism also includes a shading cloth 23 (limited use of black) wrapped around the outside of the illumination lamp stick 22. During the illumination process, all the illumination lamp sticks are wrapped by the shading cloth 23, which increases the effect of light entering the microbial degradation cylinder 1 and is secondly used to prevent light from polluting the workshop.

[0053] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
