Description

TECHNICAL FIELD

[0001] The present application relates to the sewage treatment equipment technical field, especially to the sewage aeration tank with multiple circulation and detection mechanism. BACKGROUND

[0002] With the acceleration of urbanization and the rapid development of industry, sewage treatment has become an important issue in the field of environmental protection, and the core goal of sewage treatment is to remove organic matter, nitrogen, phosphorus and other pollutants in sewage through physical, chemical and biological methods to meet the discharge standards or reuse requirements. Among many sewage treatment processes, activated sludge method and its derivative processes are widely used due to their high efficiency and stability. The performance of aeration tank, as the core unit of activated sludge treatment system, directly affects the effect and efficiency of sewage treatment.

[0003] However, there are still some deficiencies in the current design of sewage aeration tank: Firstly, in the filtration treatment link, the filtration structure used in traditional aeration tank generally has the defects of immobilization and single. Such aeration tank usually only configures a set of filtration device with fixed parameters, which cannot flexibly adjust the filtration process parameters according to the specific types and concentration distribution of pollutants in the sewage to be treated. Since the impurity components contained in sewage from different sources have significant differences, it is difficult to achieve targeted and efficient filtration treatment by using a fixed filtration method, which leads to the fact that some characteristic pollutants cannot be effectively removed, thereby adversely affecting the effect of subsequent aeration treatment link; Secondly, in terms of water quality detection and circulation treatment mechanism, the existing aeration tank lacks a perfect real-time detection and dynamic circulation treatment system. Although some aeration tank equipment is equipped with basic water quality detection device, the data obtained by detection cannot directly drive the automatic regulation and control of sewage circulation treatment process. When the detection data shows that a certain index of sewage does not meet the preset standard, the system cannot accurately guide the unqualified sewage into the filtration system for secondary treatment in time, but can only adopt the way of discharging all unqualified sewage or reprocessing the whole sewage, which not only causes waste of water resources, but also increases energy consumption cost. SUMMARY

The wastewater aeration tank with multiple circulation and detection mechanisms according to claim 5, characterized in that: The filter unit includes: a side groove, a mating block, a rotating rod, and a stop block; the side grooves are symmetrically opened on both sides of the upper end of the housing, and the side grooves are connected to the slots at the upper end of the housing; the mating block is located in the middle position of the bottom of the housing; the rotating rod is rotatably installed in the middle position of the inner side of the housing; the stop block is fixedly installed at both ends of the rotating rod, and when the stop block is upright, it can extend into the slot, and when the stop block is horizontal, it can be stored inside the housing.

7. The wastewater aeration tank with multiple circulation and detection mechanisms according to claim 6, characterized in that: The filter unit includes: a frame, a filter element, and a connecting tube; the frame is inserted into each set of slots, and circular holes are opened at both ends of the frame, with the circular hole on the upper frame communicating with the side slot; the filter element is installed on the circular hole in the frame; the connecting tube is inserted into the circular hole in the bottom frame, and the connecting tube and the filter element are in opposite positions, and the connecting tube can be inserted into the frame at the bottom of the front housing.

8. The wastewater aeration tank with multiple circulation and detection mechanisms according to claim 1, characterized in that: The detection unit includes: a fixed frame, a leak hole, and a slot; the fixed frame has a circular groove inside; the leak holes are equidistantly opened at the bottom of the fixed frame and are connected to the circular groove inside the fixed frame; the slots are located at both ends of the rear side of the fixed frame.

9. The wastewater aeration tank with multiple circulation and detection mechanisms according to claim 8, characterized in that: The detection unit includes: a rotating component, connecting holes, and a transmission wheel; the rotating component is rotatably mounted in a circular groove within a fixed frame, and the rotating component has a hollow structure; the connecting holes are equidistantly located on the outer wall of the rotating component, and all connecting holes are not on the same straight line, so the rotating component can only connect to a set of leakage holes through the connecting holes at a time; the transmission wheel is fixedly mounted on the outer front side of the rotating component.

10. The wastewater aeration tank with multiple circulation and detection mechanisms according to claim 9, characterized in that: The detection unit includes a motor, a transmission belt, a hose, and a detection controller. The motor is fixedly mounted on the upper end of the fixed frame. The two ends of the transmission belt are respectively connected to the transmission wheel and the motor. The hose is connected to each set of leak holes, but no hose is installed on the frontmost leak hole. The detection controller is mounted on the front outer end of the fixed frame, and the detection contact on the rear side of the detection controller extends into the interior of the rotating part. The detection controller can control the motor.
