Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sewage treatment, in particular to a modular combined sewage treatment and recycling device. BACKGROUND

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering and daily life of ordinary people. For impurities in water pollution, high-efficiency activated carbon can be used for adsorption. For sewage treatment and its recycling, traditional sewage treatment systems often rely on complex process flow and large equipment system. These systems not only have large floor area and high investment cost, but also have many limitations in treatment efficiency and flexibility. Especially when facing different water quality, water quantity and space limitations, traditional systems often have difficulty in flexible response. In order to overcome these limitations, modular combined sewage treatment devices have gradually emerged in recent years. The modular design concept emphasizes that the sewage treatment system is divided into several independent functional modules. These modules can be freely combined and configured according to actual needs, so as to realize the rapid construction, flexible adjustment and efficient operation of the sewage treatment system. This design not only reduces the construction cost and shortens the construction period, but also improves the adaptability and expandability of the system.

three groups of water inlet frames 2 is aligned with the bottom frame 31, the spraying pipe 34 is located at the top of the water inlet 21, so it will not interfere with the rotation of the water inlet frame 2, at this time, because the filter plate 22 is in a horizontal state, and the arc frame 312 and the vertical plate 313 are consistent with the rotation path of the water inlet frame 2, so the vertical plate 313 is inserted along the side plate of the arc frame 312 until it reaches the middle insertion hole of the arc frame 312, the electric rotating shaft drives the filter plate 22 to rotate downward, the electric rotating shaft is a combination of a motor and a rotating shaft, which can drive the filter plate 22 to rotate around the rotating shaft, in the process of rotating downward, the arc frame 312 slides downward along the surface of the vertical plate 313, at the same time, part of the solid impurities accumulated on the filter plate 22 directly falls into the bottom frame 31, then the motor drives the gear 314 to rotate, the two toothed plates 315 are engaged with the gear 314 and move in two directions respectively, the horizontal plate 36 moves outward,
