Iron carbon micro-electrolysis device

Abstract

Provided is an iron-carbon micro-electrolysis apparatus which comprises a housing, a water inlet on the housing and a water outlet on the housing; the area in the housing connected with the water inlet is a water inflow zone, the area in the lower part of the housing connected with the water inflow zone is an aeration zone, the area in the middle part of the housing located above the aeration zone is a filling material zone, and the area in the upper part of the housing located above the filling material zone is a water outflow zone; the water inflow zone, the filling material zone and the water outflow zone are separated from each other by baffle plates, the aeration zone is provided with an aeration pipe, and the filling material zone is filled by iron dust filtering layers and carbon filtering layers, with each iron dust filtering layer stacking on each carbon filtering layer. The invention has the characteristics of a reasonable structure, high treating efficiency and a long service life.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to an unpowered iron-carbon micro-electrolysis water treatment device. Background technique [0002] The coating process is widely used in the surface treatment of automobiles. In the production process, wastewater is basically generated. The pollutants in the wastewater are complex, contain a variety of toxic substances, have high concentrations, and have poor biodegradability. Therefore, the treatment of automobile painting wastewater It has become a major problem in today's sewage treatment engineering. [0003] Micro-electrolysis method, also known as internal electrolysis method, iron-carbon method, corrosion battery method, iron filings filtration method, zero-valent iron method, etc., uses iron and carbon in iron filings to form a primary battery to achieve the degradation of pollutants in water. Because this method has the advantages of wide application ran...
