Abstract

The invention relates to a constructed wetland heavy metal deionization purification system based on a super capacitor. The technical scheme is as follows: the provided purification system is formed by a horizontal subsurface flow constructed wetland (2) and a super capacitor system which are connected through a water pipe. The horizontal subsurface flow constructed wetland (2) is composed of natural reaeration channel regions (4), a wetland processing region (14) and an artificial aeration region (15). A lower layer (17) is filled with gravels, and an upper layer (5) is filled with sandy soil. The wetland water outlet (13) of the horizontal subsurface flow constructed wetland (2) is communicated with the water inlet of a two-three-way valve (12). A water inlet and a water outlet of a magnetic exciter are communicated with the water outlet of the two-three-way valve (12) and a capacitor water inlet (22) of a super capacitor (8) correspondingly. The capacitor water outlet (26) of the super capacitor (8) is communicated with water inlets of a one-three-way valve (10) and an automatic control system (11). The purification system is advantaged by good purifying effects, little energy consumption, short processing cycle, low maintenance expense, restorable landscape ecological function, no secondary pollution and sustainable utilization.

Description

technical field [0001] The invention belongs to the technical field of heavy metal sewage treatment. Specifically, it relates to a supercapacitor-based heavy metal deionization and purification system for constructed wetlands. Background technique [0002] Constructed wetland is a semi-ecological sewage treatment system through artificial design and transformation. It is mainly composed of three parts: soil matrix, aquatic plants and microorganisms. Through the synergy of physics, chemistry and biology in the natural ecosystem to achieve Purification of sewage. Constructed wetlands mainly use natural processes such as wetland vegetation, soil and related microbial lag to assist in the treatment of wastewater, which is an effective ecological restoration technology. Specific forms include surface flow constructed wetlands, horizontal subsurface flow constructed wetlands, vertical subsurface flow constructed wetlands and composite vertical flow constructed wetlands.
