specific Embodiment 1

[0038] Specific embodiment one is water inlet type at both ends: details attached figure 1 And figure 2 . This type requires the construction of an overflow weir 13. The water flow enters the gravity turbine through the inlet pipe and valve 17 (if there is excess flow, it flows out through the bypass pipe on the inlet pipe and valve 17 or overflows through the top of the overflow weir). The water turbine and the biological drum are driven to rotate and enter the oxidation tank 12. The water bucket of the water turbine is composed of an impeller 2, two side plates 15 of the water turbine and a bottom plate 16 of the water bucket. The impeller 2 of the water turbine adopts a spiral blade with lower resistance. The connection between the impeller 2 and the water bucket bottom plate 16 can form a certain clamp. The angle can also be 90 degrees. The bucket bottom plate 16 and the two turbine side plates 15 also form an enclosed pontoon, and the bucket bottom plate 16 is also the c...

specific Embodiment 2

[0040] Specific embodiment two is the central water inlet type: details are attached image 3 And Figure 4 . Basically similar to the first embodiment, the difference is that the water turbine is set in the middle, and the number of water turbines is changed from two to one. The width of the water turbine may change due to changes in the amount of water. In addition, the inlet pipe and valve 17 and the outlet pipe and valve The position of 18 has also changed accordingly. The water flow enters from the middle and flows to both ends. It should also be pointed out that when the water intake cannot provide sufficient power, auxiliary power can be added, including speed monitoring sensor 23, variable frequency motor and reducer 24 and one-way (clutch) bearing 25. In this way, the minimum investment in power can be achieved and the aerobic treatment effect can be ensured. This equipment can also be used in the use environment of the non-oxidation tank 12. When used in this enviro...

specific Embodiment 3

[0041] Specific embodiment three is a radial water inlet type: details attached Figure 5 And Image 6 . The biggest feature of this model is that the body is both a hydraulic turbine and a biological drum. The pontoon shaft 1 of the biological drum is also the pontoon shaft 1 of the water turbine. The water turbine belongs to the propeller type water turbine. The length of the impeller 2 of the water turbine is the same as the length of the fuselage. Each impeller 2 is divided into two sections, one of which is rectangular and is fixed vertically on the outer wall of the pontoon. The spiral impeller 2 of each module is provided with several speed-adjusting flower baskets 20, and the angle of the movable impeller 2 is changed by adjusting the length of the speed-adjusting flower basket 20, so as to achieve the purpose of speed adjustment. The gap between the impeller 2 is provided with a lightweight packing 3, and the two ends of each module are provided with a packing bracke...

Abstract

The invention mainly relates to a hydraulic biological drum for river self-purification. The hydraulic biological drum is mainly characterized by consisting of a floating type water turbine, a float type biological drum, a hydraulic mud discharge facility, a power transmission mechanism and auxiliary power. Water power is taken as the main power source. When the influent flow is large, only hydraulic drive is employed. When the influent flow is small and hydraulic drive is difficult, by means of the one-way (clutch) bearing 25 set on a power rotation shaft, superposition of external power and hydraulic power can be realized. A rotation speed monitoring sensor (or dissolved oxygen sensor) 23 provides a signal, which is converted into a control signal by PLC to control the rotation speed of a variable frequency motor 24 so as to realize minimum input of power. The hydraulic biological drum provided by the invention can be widely applied to river pollution treatment, and has the characteristics of long rotation shaft, adjustable rotation speed, low running cost, and unattended operation under some conditions, thus being energy saving sewage treatment equipment worth popularization.

Description

Technical field [0001] The invention relates to an innovative invention of sewage treatment equipment in the sewage treatment industry. Background technique [0002] Aerobic biochemical treatment is an important technical means of pollution treatment. Conventional aerobic biochemical treatment often consumes a lot of energy. Taking Xiamen as an example, when the activated sludge method is used for treatment and reaches the second-level emission standard, the power consumption cost often accounts for 25-45% of the operating cost, which is the largest expenditure in the operating cost. Therefore, reducing the expenditure on power consumption through technical means is the key to effectively reducing the operating costs of sewage treatment. [0003] Among the nationally controlled sections of the ten major river basins in the 2013 Bulletin of the State of the Environment in China, the proportions of sections with water quality of Grade I to III, Grade IV to V and worse than Grade V ...
