DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art belong to the scope of protection of the present application.

[0024] Embodiments of the present application:

[0025] As shown in the drawings, Figs. 1-2 A kitchen waste liquid carbon source storage device for a sewage treatment plant, comprising a tank body, the tank body is connected with a liquid adding pipeline, a liquid adding pump 35 is arranged on the liquid adding pipeline; the tank body has two, the liquid adding pipeline comprises two liquid adding branch pipes 31 and one liquid adding main pipe 33, one end of the two liquid adding branch pipes 31 is connected with one tank body respectively, the other end of the liquid adding branch pipe 31 is connected with the liquid adding main pipe 33, and the liquid adding pump 35 is arranged on the liquid adding main pipe 33.

[0026] The two tank bodies are defined as a first tank body 11 and a second tank body 12, one end of the two liquid adding branch pipes 31 is connected with the first tank body 11 and the second tank body 12 respectively, the connection position is below the middle part of the tank body, and the liquid adding pump 35 is used for conveying kitchen waste liquid to other processes. The tank body is also commonly known as a dosing tank in the sewage treatment industry, and the liquid adding pump 35 is called a dosing pump.

[0027] The two liquid adding branch pipes 31 are respectively provided with a first electric valve 32, and the liquid adding main pipe 33 is provided with a second electric valve 34 on the pipe section between the two liquid adding branch pipes 31. The electric valve in the embodiment can adopt a solenoid valve, or other existing electric valves; the first electric valve 32 and the second electric valve 34 are independently controlled, so that the liquid adding pump 35 can selectively extract kitchen waste liquid from the two tank bodies.

[0028] The tank body is connected with a circulating pipeline, and a circulating pump 45 is arranged on the circulating pipeline. For the convenience of understanding, the circulating pipeline is described separately: the circulating pipeline comprises a first circulating pipeline 41 and a second circulating pipeline 42, the circulating pump 45 is connected to the first circulating pipeline 41, both ends of the first circulating pipeline 41 are connected to the first tank body 11, and both ends of the second circulating pipeline 42 are connected to the first circulating pipeline 41 and the second tank body 12 respectively. The third electric valve 43 and the fourth electric valve 44 are arranged on the first circulating pipeline 41 and the second circulating pipeline 42 respectively. When the third electric valve 43 and the fourth electric valve 44 are both opened, the circulating pump 45 is started to make the kitchen waste liquid in the tank body circulate; of course, the first electric valve 32 and the second electric valve 34 are also opened, and the bottoms of the two tank bodies are also in a state of communication during circulation. By using the circulating pipeline, the flowability of the waste liquid in the tank body is improved, the deposition is reduced, and the blockage in the conveying process is reduced; a small amount of deposition is allowed to be deposited at the bottom of the tank body, and the conical structure at the bottom of the tank body is convenient for collecting waste residues, and the bottom valve is opened regularly for manual cleaning.

[0029] The top of the tank body is connected with a deodorizing pipeline 5, the fifth electric valve 51 is arranged on the deodorizing pipeline 5, and the deodorizing pipeline 5 is used to connect a deodorizing device. The deodorizing pipeline 5 is connected with both tank bodies. The deodorizing device is relatively mature, and can adopt the existing technology, which will not be described in detail. Generally, it comprises an air extractor, a gas absorption and decomposition module, and is discharged into the atmosphere after treatment; the odor generated by the kitchen waste liquid is mainly hydrogen sulfide and ammonia. The fifth electric valve 51 is normally closed, and the deodorizing device can be opened at a regular time, and the fifth electric valve 51 is opened at the same time.

[0030] A gas detection sensor (not shown) is arranged at the top of the tank body, such as a hydrogen sulfide gas detection sensor mounted on the upper side of the tank cover. The hydrogen sulfide gas detection sensor transmits data to a monitoring room in real time to understand the odor situation around the tank body outside to achieve the purpose of monitoring. If the detection value is greater than the set value, an alarm signal is given to manually check whether the deodorizing pipeline 5 is invalid or to check other aspects. The ammonia detection is similar to the odor detection, and an ammonia detection sensor is arranged, and the two sensors are integrated into one detection module. In other embodiments, the odor detection module can also be mounted on the deodorizing pipeline 5 and supported by the deodorizing pipeline 5.

[0031] One of the liquid adding branch pipes 31 is connected with a flushing pipe 2 for connecting with a backwashing system. The flushing pipe 2 is connected with the liquid adding branch pipe 31 and the liquid adding main pipe 33 through a tee joint, and the presence of the flushing pipe 2 does not affect the extraction of the kitchen waste liquid by the liquid adding pump 35 when the backwashing function is not used. The backwashing system comprises a water pump and a clean water tank, and an electromagnetic valve is arranged on the flushing pipe 2. When the tank body needs to be cleaned, after the kitchen waste liquid in the tank body is basically extracted and before new kitchen waste liquid is stored next time, the backwashing system can be used to inject flowing water into the tank body for flushing. When flushing, the first electric valve 32 and the second electric valve 34 are opened, and the two tank bodies can be filled with water, or one of the tank bodies can be selectively flushed. After a certain amount of clean water is injected into the tank body, the circulating pump 45 can be started to circulate the flushing liquid for a certain time, so as to improve the cleaning effect. The cleaned flushing liquid can be discharged into a subsequent process.

[0032] The kitchen waste liquid carbon source storage device of the sewage treatment plant further comprises an anti-overflow wall 6 which is arranged around the tank body. The anti-overflow wall 6 is made of concrete pouring or steel plate welding, and is not limited to each way; the height of the anti-overflow wall 6 is lower than that of the tank body, and does not affect the personnel to enter the anti-overflow wall 6 to perform routine maintenance on the tank body. Both tank bodies are located in the rectangular space surrounded by the anti-overflow wall 6. Generally, the anti-overflow wall 6 does not work, but if the tank body is damaged and the kitchen waste liquid leaks, the kitchen waste liquid is in the rectangular space surrounded by the anti-overflow wall 6 and does not flow everywhere, thereby reducing pollution.
