Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and specifically relates to a wastewater treatment device based on an inorganic ceramic membrane. Background Art

[0002] Wastewater treatment refers to the use of physical, chemical, and biological methods to treat wastewater, purify the wastewater, reduce pollution, and achieve the technology of wastewater recycling and reuse to make full use of water resources. Common agents for wastewater treatment include flocculants, coagulant aids, conditioning agents, etc., and treatment technologies include pretreatment, new fillers, ceramic membranes, etc.

[0003] An inorganic ceramic membrane is an inorganic or polymer material with a special selective separation function. It can separate a fluid into two non-communicating parts, allowing one or several substances to pass through while separating other substances. Membrane separation technology, with its characteristics of high efficiency, energy conservation, environmental protection, and molecular-level filtration, has been widely applied in fields such as medicine, water treatment, chemical engineering, electronics, and food processing. It has become one of the most important technologies in separation science in this century and is recognized as one of the most significant industrial technologies in the 21st century. Membrane technology is a new emerging green industrial technology.

[0004] Existing membrane filtration equipment cannot clean the outer wall of the inorganic ceramic membrane. In the case of long-term use, dirt will adhere to the outer wall of the inorganic ceramic membrane, reducing the water filtration efficiency of the inorganic ceramic membrane. Existing equipment only replaces the inorganic ceramic membrane, which will increase the water filtration cost, and the dirt on the outside of the inorganic ceramic membrane not being cleaned in time will also lead to a decline in the filtration efficiency. Therefore, a wastewater treatment device based on an inorganic ceramic membrane is needed. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a wastewater treatment device based on an inorganic ceramic membrane.

[0006] The technical solution of the present invention is: A wastewater treatment device based on an inorganic ceramic membrane, including a water filtration chamber. The left side of the water filtration chamber is fixedly connected with a water inlet pipe, and the water inlet pipe is externally connected to a wastewater source.
