Farmland water returning ditch purification system combining ecological floating bed and iron-carbon micro-electrolysis

Abstract

The invention discloses a farmland water returning ditch purification system combining an ecological floating bed and iron-carbon micro-electrolysis. The farmland water returning ditch purification system comprises a floating bed and an iron-carbon micro-electrolysis mechanism, wherein the floating bed consists of a floating bed base and a plurality of floating bed planting baskets; the iron-carbon micro-electrolysis mechanism comprises an iron-carbon micro-electrolysis grating and an iron-carbon micro-electrolysis storage device; the iron-carbon micro-electrolysis storage device comprises a box body, a reel, a buckle, a coil spring and a fixer; and a long hole is formed in the bottom of the box body in the length direction, the upper end of the iron-carbon micro-electrolysis grating penetrates through the long hole to be fixedly connected with the coil spring, and the lower end of the iron-carbon micro-electrolysis grating is fixedly connected with the bottom of the water returning ditch. Organic matters and nitrogen and phosphorus pollutants in water are efficiently removed in various physical, chemical and biological modes through various modes of floating bed plants, biological membranes hung on the floating bed plants, an iron-carbon micro-electrolysis device and submerged plants, so that farmland recession water quality purification is realized, and agricultural non-point source pollution is reduced. Meanwhile, the problems that floating bed plants and submerged plants are dormant and wither in the dry season of the ditch and iron-carbon micro-electrolysis filler is prone to oxidation and failure are solved.

Description

technical field [0001] The invention belongs to the technical field of agricultural non-point source pollution control, in particular to a farmland ditch purification system combining an ecological floating bed and iron-carbon micro-electrolysis. Background technique [0002] Agricultural non-point source pollution refers to the excessive or improper use of pesticides and fertilizers in agricultural production activities, causing a large amount of organic pesticides and nitrogen and phosphorus nutrients to flow into receiving water bodies through irrigation retreat and rainwater runoff, resulting in eutrophication of water bodies and restricting agricultural availability. Continuous development. Therefore, solving the problem of nitrogen and phosphorus pollution in farmland receding water is of great significance for protecting river ecosystems and promoting the green development of agriculture. [0003] Existing technical measures to solve agricultural non-point source pol...

Problems solved by technology

However, if the iron-carbon filler is exposed to the air for a long time, the filler will fail and the water purification effect will decrease.
