Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-3 As shown, this embodiment provides a modular diversion clarifier, including a clarifier body 2, wherein two clarification mechanisms are arranged inside the clarifier body 2, and the clarification mechanisms include a water outlet weir 12, a mud-water separator 11, a support frame 10, an inner folding plate 13, an outer folding plate 14, an outer baffle 15 and an inner baffle 16; the water outlet weir 12 is connected to the inner wall of the clarifier body 2; the mud-water separator 11 is arranged below the water outlet weir 12; the support frame 10 is used to support the mud-water separator 11; the inner folding plate 13 and the outer folding plate 14 are arranged below the support frame 10; the inner baffle 16 and the outer baffle 15 are arranged on the side of the mud-water separator 11, and are connected to the inner wall of the clarifier body 2 and the support frame 10.

[0024] Compared with the prior art, the clarification mechanism of the utility model includes a water outlet weir 12, a mud-water separator 11, a support frame 10, an inner folding plate 13, an outer folding plate 14, an outer baffle 15 and an inner baffle 16. The clarification mechanism is provided with a multi-fold plate structure, which is conducive to forming specific channels for sludge, sewage and air, and has an excellent solid-liquid separation effect; the clarification mechanism of the utility model with a multi-fold plate structure is conducive to the use of modular design, can be widely used in various activated sludge biochemical processes, has a wide range of application scenarios, is easy to install and maintain; the utility model has a non-powered design, does not need to set up a sludge reflux device, and saves energy.

[0025] like Figure 1-3 As shown, the two clarification mechanisms in the clarifier body 2 of this embodiment are symmetrical structures; thus, an air flow channel is formed between the clarification mechanisms, which is beneficial to improving the solid-liquid separation effect. Preferably, the mud-water separator 1111 can be provided with an inclined plate or inclined tube filler to facilitate the solid-liquid separation of the mixed liquid through the mud-water separator 11, which is beneficial to improving the solid-liquid separation effect.

[0026] like Figure 1-3 As shown, the outlet weir 12 of this embodiment is configured as a triangular weir plate structure, so that the clarified sewage can be easily discharged into the outlet weir 12 .

[0027] like Figure 1-3 As shown, the inner folding plate 13 and the outer folding plate 14 of this embodiment are connected to both sides of the inner wall of the clarifier body to form a flow channel for sludge and sewage; it is convenient for the mixed liquid to flow back to the aerobic biochemical reaction tank 1 through the outer baffle 15 after entering.

[0028] like Figure 1-3 As shown, the inner baffle 16 and the outer baffle 15 of this embodiment are connected to both sides of the inner wall of the clarifier body to form a flow channel for air and reflux liquid; in this way, the compressed air is discharged after passing through the channel.

Preferably, an aeration device 3 can be provided at the bottom of the aerobic biochemical reaction tank 1, and the aeration device 3 is provided below the clarifier body 2.

[0030] Working principle: When solid-liquid separation is required, the aeration device 3 inside the aerobic biochemical reaction tank 1 is first started. The aerobic biochemical reaction tank 1 undergoes an oxidation reaction with the oxygen provided by the aeration device 3. After the mud-water mixture enters the special channel formed by the inner folding plate 13 and the outer folding plate 14, part of the mixture passes through the mud-water separator 11 at the top of the support frame 10 for solid-liquid separation. After the sewage is clarified, it enters the outlet weir 12 for collection and is discharged from the aerobic biochemical reaction tank 1. Part of the mixed liquid enters the outer baffle 15 and the inner baffle 16 to form a mixed liquid reflux channel and refluxes to the inside of the aerobic biochemical reaction tank 1. The sludge falls to the surface of the inner folding plate 13 by gravity sedimentation and then refluxes to the aerobic biochemical reaction tank 1. The air provided by the aeration device 3 is discharged from the aerobic biochemical reaction tank 1 through the channel formed by the two outer baffles 15. After the above process, the air, sewage and sludge pass through the special channel formed by the folding plate, thereby achieving the functions of sewage clarification, sludge reflux and mixed liquid reflux.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
