Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to an intelligent water quality monitoring device for a sewage treatment station. Background Art

[0002] Intelligent water quality monitors are primarily used for online monitoring of water quality in rivers, lakes, corporate outfalls, environmental training labs, and process data from sewage treatment plants (stations). Modern intelligent water quality monitors utilize a modular structure, built-in automated programs, and offer both remote and on-site control capabilities. They can interface with on-site PLCs and remote cloud platforms, meeting both short-term and mid- to long-term intelligent upgrade needs. These monitors transcend the limitations of traditional online testing equipment and can be equipped with a variety of sensor probes tailored to customer needs. They can rapidly measure water parameters such as pH, dissolved oxygen, ORP, COD, sludge concentration, and ammonia nitrogen in multiple on-site locations.

[0003] When monitoring sewage, existing intelligent water quality monitors generally extract and monitor sewage at a specific location, and cannot extract and monitor sewage at multiple locations in sequence. This will cause the monitoring results to deviate. After monitoring the sewage, samples of the monitored sewage cannot be retained, which will affect the subsequent further monitoring of the sewage.

In some embodiments, several sewage pipes 12 can be provided, and the several sewage pipes 12 are provided at different specific positions. The sewage can be pumped into the monitoring chamber 2 through the sewage pump 11.

[0025] The sewage inlet pipe 3 is connected to several branch pipes 4, and the water outlet ends of the several branch pipes 4 are connected by a connecting pipe 5. The water outlet end of the connecting pipe 5 is connected to a sewage collecting pipe 6, and the water outlet end of the sewage collecting pipe 6 is connected to a first three-way valve 7. The other two ports of the first three-way valve 7 are connected to a monitoring pipe 8. Through the set branch pipes 4, sewage at different locations can be extracted and diverted, replacing the traditional method of extracting and monitoring at a single specific location, thereby improving the effect of sewage monitoring and the accuracy of sewage monitoring data.

[0026] A first flow valve is provided on the branch pipe 4. Through the first flow valve, after the sewage enters the sewage inlet pipe 3, the first flow valve on the corresponding branch pipe 4 is adjusted according to the needs of sewage circulation, so that sewage at different positions can enter different branch pipes 4.

[0027] A sampling mechanism is provided on the branch pipe 4, and the sampling mechanism includes a sampling tube 9 and a sampling bottle 10. The sampling tube 9 is provided on the side wall of the branch pipe 4 and is connected to the branch pipe 4. The sampling bottle 10 is detachably connected to the water outlet end of the sampling tube 9. Through the provided sampling mechanism, the sewage flowing in the branch pipe 4 can be stored, so that the sewage extracted at different positions can be sampled, and it is convenient for workers to take away the sampling bottle 10 for further monitoring or retention of the sewage.

[0028] The outlet ends of the two monitoring pipes 8 are connected by a drain pipe 18. The outlet end of the drain pipe 18 extends to the outside of the monitoring chamber 2. The monitoring pipe 8 is provided with a number of monitoring sensors 19. In some embodiments, the monitoring sensors 19 can be pH monitoring sensors 19, dissolved oxygen monitoring sensors 19, ORP monitoring sensors 19, COD monitoring sensors 19, sludge concentration monitoring sensors 19 and ammonia nitrogen monitoring sensors 19, etc., which can monitor parameters such as pH, dissolved oxygen, ORP, COD, sludge concentration, ammonia nitrogen, etc. in sewage.

[0029] The sampling tube 9 is provided with a second flow valve, through which the sewage flowing in the sewage pipe can enter the sampling bottle 10, so that the sampling bottle 10 can retain the sewage in the branch pipe 4.

[0030] The outer fixed sleeve of the water outlet end of the sampling tube 9 is provided with a connecting sleeve (14), the inner wall of the connecting sleeve (14) is provided with an internal thread, and the sampling bottle 10 is provided with an external thread adapted to the internal thread. Through the provided connecting sleeve (14), the sampling bottle 10 can be disassembled and connected to the sampling tube 9. After sampling, the sampling bottle 10 can be removed, or a new sampling bottle 10 can be installed on the sampling tube 9.

[0031] A cleaning pump 15 is fixedly connected to the monitoring chamber 2, and the water inlet end of the cleaning pump 15 is connected to a water pumping pipe 16 extending to the outside of the monitoring chamber 2, and the water outlet end of the cleaning pump 15 is connected to a water spraying pipe 17, and the water outlet end of the water spraying pipe 17 is connected to the third port of the second three-way valve 1313.

[0032] The monitoring chamber 2 is provided with a cabinet door 20 , and the cabinet door 20 is provided with a transparent observation window.

[0033] The working principle of the utility model is as follows: first, the sewage pump 11 is started to pump sewage into the sewage inlet pipe 3, and then the first flow valve on the corresponding branch pipe 4 is opened to allow the sewage to flow into the connecting pipe 5, the sewage collection pipe 6, the monitoring pipe 8 and the drain pipe 18 in sequence. While the sewage is flowing, the monitoring sensor 19 measures the pH, dissolved oxygen, ORP, COD, sludge concentration, ammonia nitrogen and other parameters in the sewage. At the same time, the second flow valve on the sampling pipe 9 is opened to allow the sewage to enter the sampling pipe 9. The sewage then passes through the sampling pipe 9 and enters the sampling bottle 10, and the measured sewage is sampled and processed;

[0034] When it is necessary to monitor the sewage at a new location, first start the cleaning pump 15 to pump clean water into the sewage inlet pipe 3. The clean water flows through the branch pipe 4, the connecting pipe 5, the sewage collecting pipe 6, the monitoring pipe 8 and the drain pipe 18 in turn to clean the branch pipe 4, the connecting pipe 5, the sewage collecting pipe 6, the monitoring pipe 8, the drain pipe 18 and the monitoring sensor 19. Then, similarly, the sewage at the new location is extracted and sampled.
