Embodiment Construction

[0042] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0043] A kind of MBR water treatment system utilizing siphon to produce water, such as figure 1 , 2 As shown, it includes a biological treatment unit and a submerged membrane treatment unit. The biological treatment unit includes an anaerobic tank 1, an anoxic tank 3 and an aerobic tank 4. A stirring device 2 can be installed in the anaerobic tank 1 and anoxic tank 3. The submerged membrane processing unit includes a membrane box 12 and a group of submerged membrane stacks 8 installed in the membrane box 12. The submerged membrane stack 8 adopts a frameless full-channel filter membrane stack. The water inlets of the frameless full-channel filter membrane module are respectively connected to the main water inlet pipe 23 through the water inl...

Abstract

The invention discloses an MBR (membrane bioreactor) water treatment system by siphon water production. The treatment system comprises a biological treatment unit and a submerged membrane treatment unit, the biological treatment unit comprises an anaerobic tank, an oxygen deficit tank and an aerobic tank, the submerged membrane treatment unit comprises a membrane box and one group of submerged membrane stacks mounted in the membrane box, water inlets of the submerged membrane stacks are connected with a main water inlet pipe through water inlet branch pipes, and the main water inlet pipe is connected with a water outlet of the biological treatment unit. The treatment system is characterized in that siphon pipelines are arranged at the bottoms of the submerged membrane stacks, siphon valvesare mounted on the siphon pipelines, the siphon pipelines are connected with vacuum pipes, vacuum values are mounted on the vacuum pipes, the vacuum pipes are connected with a vacuum pump, the siphonpipelines of one group of submerged membrane stacks are connected with water outlet branch pipes, the water outlet branch pipes are connected with a main water outlet pipe, and a water production valve is mounted on the main water outlet pipe. According to the MBR water treatment system by siphon water production and a treatment method of the system, running energy consumption of an MBR process can be effectively reduced, and the running cost of the treatment process is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an MBR water treatment system using siphon to produce water and a method thereof. Background technique [0002] my country is one of the countries with poor per capita water resources in the world. With the economic development of our country, the demand for water resources is increasing day by day, exacerbating the shortage of water resources, and the amount of sewage treatment is also greatly increasing. Sewage treatment and resource utilization is an effective way to solve the shortage of water resources. Therefore, it is very necessary to reduce the cost of sewage treatment by improving the efficiency of sewage treatment. [0003] The biofilm reactor (MBR) process is a sewage treatment process that combines membrane separation technology with biological treatment. This process uses high-efficiency membrane filtration to replace the sedimentation tank in the traditio...
