Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrochemical phosphorus removal technology, specifically an electrochemical phosphorus removal device. Background Technology
[0002] With water pollution control receiving much attention, electrochemical phosphorus removal devices have emerged. These devices utilize electrochemical technology, using metals such as aluminum and iron as anodes, to generate metal ions under the action of direct current. Phosphorus is removed from wastewater through reactions such as flocculation and precipitation. They have high phosphorus removal efficiency and are widely used in the treatment of domestic and industrial wastewater.
[0003] Existing electrochemical phosphorus removal devices rely on electrolysis to convert phosphorus ions in wastewater into harmless precipitates, which are then effectively removed through filtration. However, the electrode spacing is fixed, making it impossible to flexibly adjust the electrolysis intensity based on the phosphorus concentration in the water. If the raw water phosphorus concentration is high, the fixed spacing may result in insufficient electrolysis current and low phosphorus removal efficiency. Conversely, if the raw water phosphorus concentration is low, the fixed spacing may lead to excessive current, wasting energy and potentially exacerbating electrode wear. To address these shortcomings, this invention provides an electrochemical phosphorus removal device to solve the aforementioned problems. Utility Model Content
