Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a wastewater concentration control device for experiments. Background Art

[0002] The operation quality and high efficiency of anaerobic reactors depend to a large extent on whether the best anaerobic granular sludge with excellent settling performance and methanogenic activity can be cultivated. On the contrary, if the sludge in the reactor exists in the form of loose flocs, sludge loss is often prone to occur, and the reactor cannot operate stably at a high volumetric load rate. The advantages of screened toxic anaerobic granular sludge are mainly reflected in the following aspects: sludge granulation can improve its settling performance, prevent sludge loss, and maintain a high sludge concentration in the reactor; granular sludge can be retained in the reactor for a long time, has a long solid retention time (SRT), can shorten the sewage hydraulic retention time (HRT), and make the reactor have a high treatment efficiency.

[0003] After the granular sludge is formed, methanogens are mainly concentrated inside the granules, while hydrolytic fermentation bacteria and acid-producing bacteria are mainly on the surface of the granular layer. This structure provides a protective layer or buffer layer for methanogens, which not only maintains a low redox potential, which is conducive to the growth of methanogens, but also improves the sludge's ability to resist changes in pH, temperature and harmful substances, and also improves its ability to resist shock loads. The number and concentration of methanogens need to be measured to improve the above-mentioned hydrolysis and fermentation efficiency.

[0004] In order to verify the above conclusions, a small volume container is needed for verification. Therefore, it is necessary to invent an experimental wastewater concentration control device to solve the above problems. Summary of the invention

An evaporation box 4 is clamped inside the external box 1, and the top surface of the evaporation box 4 abuts against the bottom surface of the internal box 5. A first partition grille 6 is detachably inserted in the evaporation box 4, and a second partition grille 7 is detachably clamped in the internal box 5. The first partition grille 6 can divide the evaporation box 4 into a plurality of evaporation chambers, and the second partition grille 7 can divide the internal box 5 into a plurality of culture chambers.

[0017] A wind control pipe 8 for letting in evaporative hot air is arranged in the space below the evaporation box 4 inside the external box 1. A plurality of shunt air ducts 9 are connected to the side walls around the wind control pipe 8. The circulation of the plurality of shunt air ducts 9 is automatically controlled and can be detachably connected to the corresponding evaporation chambers. A culture box 11 with an open top end can be detachably arranged in each culture chamber. A box cover 12 can be detachably abutted against the top of each culture box 11. A horizontal pipe 23 for letting in water is longitudinally slidably arranged in the space above the external box 1. A plurality of shunt water pipes 14 with automatically controlled circulation are detachably connected to the side walls around the horizontal pipe 23. The plurality of shunt water pipes 14 longitudinally penetrate the corresponding box covers 12 respectively. By changing the shapes of the first partition grille 6 and the second partition grille 7, the number of partitions of the evaporation box 4 and the internal box 5 can be changed accordingly.

[0018] A plurality of connecting seats 13 are connected to the side walls of the horizontal tube 23, one end of the diverter water pipe 14 is detachably connected to the connecting seat 13, the other end of the diverter water pipe 14 longitudinally penetrates the box cover 12 and extends to the inside of the incubator 11, one end of the diverter water pipe 14 located in the incubator 11 is connected to a guide cover 15, a diverter plate 16 is detachably embedded in the guide cover 15, one incubator 11 corresponds to one diverter water pipe 14, the water entering the diverter water pipe 14 is finally evenly sprayed in the corresponding incubator 11 through the diversion effect of the guide cover 15 and the diverter plate 16, and the water replenishment is completed.

[0019] The box cover 12 is provided with a plurality of evaporation holes 17, each of which is removably provided with a blocking block 18, and a lifting rack 19 is connected to a symmetrical position at the top of each box cover 12. During the cultivation process, the blocking block 18 is passed through the evaporation hole 17. During the evaporation process, the blocking block 18 is taken out from the evaporation hole 17, so that the evaporated water vapor is discharged therefrom.

[0020] A side mounting seat 2 is connected to one side wall of the external box 1, and a water storage component 3 is detachably mounted on the top of the side mounting seat 2. The water storage component 3 is detachably connected to one end of the cross pipe 23 via a connecting hose 10.

[0022] The automatic flow control of the diversion air duct 9 and the diversion water pipe 14 is achieved through solenoid valves. The work of each solenoid valve works in coordination without interfering with each other, thereby achieving automatic flow control of different diversion air ducts 9 and diversion water pipes 14.

[0024] Moreover, during the experiment, when the water content in a certain incubator 11 is relatively low, water can be added to the incubator 11 by opening the corresponding diversion water pipe 14; and when the soil water content in a certain incubator 11 is relatively high, hot air can be transported to the corresponding evaporation chamber by opening the corresponding diversion water pipe 14, thereby evaporating the excess water in the incubator 11.

[0025] In the present invention, the evaporation box 4 and the built-in box 5 are divided into multiple areas by the first partition grille 6 and the second partition grille 7, so that each area is in the same culture environment, that is, the wastewater concentration of multiple culture boxes 11 is individually controlled at the same time. At the same time, by controlling the corresponding shunt air duct 9 to deliver evaporated hot air to the corresponding evaporation chamber, the hot air and evaporation in the corresponding culture box 11 are individually controlled, which is more conducive to the normal growth of methane bacteria. In a single culture process, multiple culture boxes 11 can culture methane bacteria in different areas without interfering with each other, and at the same time serve as a reference for each other, so as to intuitively obtain the growth status of methane bacteria and the control status of wastewater concentration.
