KEE three-level biochemical filter

Abstract

The invention discloses a KEE three-level biochemical filter which comprises a glass reinforced plastic tank; a first chamber is formed on the glass reinforced plastic tank; a waterproof motor is arranged on one side of the first chamber; a rotating shaft is fixedly arranged on an output shaft of the waterproof motor; a second chamber is formed on the glass reinforced plastic tank; the second chamber is located on the other side of the first chamber; one end of the rotating shaft away from the waterproof motor is successively penetrated through the first chamber and the second chamber and extends to one side of the second chamber away from the first chamber; two biological turntables are fixedly arranged on the outer side of the rotating shaft; the two biological turntables are respectively located in the first chamber and the second chamber; a secondary sedimentation tank is arranged in the glass reinforced plastic tank. A non-aerating system provided by the invention has the advantages of high efficiency, low consumption, labor-saving effect, beautiful appearance, land-saving effect, customization, durability, no odor, and the like; water treatment effect is excellent; treatmentcost is low; the requirements of customers can be quickly met; green recycling of water resource can be realized.

Description

technical field [0001] The invention relates to the technical field of water filtration and advanced treatment, in particular to a KEE three-stage biochemical filter. Background technique [0002] The existing filtering device has the following disadvantages when used: 1. The common filtering process with interception as the purpose and means cannot further remove the suspended solids SS and BOD and other residual organic substances in the water. 2. The traditional filtration process cannot maintain the balance between sludge generation and digestion and degradation of the filter, and the sludge needs to be washed repeatedly. 3. Filtration processes such as ordinary sand filtration require pumping or high water level operation. The investment of the filtration system is high, the operation management is complicated, and the operation energy consumption is large. 4. The most widely used activated sludge method in China mixes wastewater with activated sludge (microorganisms) ...

AI Technical Summary

Problems solved by technology

[0002] Existing filter devices have the following disadvantages when in use: 1. Ordinary filtration processes for the purpose and means of interception cannot further remove residual organic substances such as suspended solids SS and BOD in water

2. The traditional filtration process cannot maintain the balance between sludge production and digestion and degradation of the filter, and the sludge needs to be washed repeatedly

3. Filtration processes such as ordinary sand filtration require pumping or high water level operation. The investment of the filtration system is high, the operation management is complicated, and the operation energy consumption is large.

[0003] In the prior art, the aeration process, oxidation ditch process, and MBR process (membrane bioreactor) for sewage treatment using the activated sludge method generally have infrastructure costs, high operating costs, high energy consumption, complicated management, and prone to pollution. Mud swelling, sludge floating and other problems, and inorganic nutrients such as nitrogen and phosphorus cannot be removed, so we proposed KEE three-stage biochemical filter to solve the above problems
