Active iron purifier and bank slope wetland system coupled purifying culture pond drainage system

Abstract

The invention relates to an active iron purifier and bank slope wetland system coupled purifying culture pond drainage system and a drainage method. The system is structurally characterized in that a trash rack and a filter screen are arranged at an inlet of a drainage pipe of a culture pond, the lower end of the drainage pipe is provided with three-way pipes which are communicated with active iron purifiers, a water outlet pipe of each active iron purifier is communicated with a water permeable pipe which is buried inside a gravel bed, a non-sand concrete partition A is arranged between the gravel bed and a bank slope subsurface wetland, and a non-sand concrete partition B is arranged between the bank slope subsurface wetland and a river channel. A water outlet pipe valve is arranged on the water outlet pipe of each active iron purifier, a flushing drainage pipe valve is arranged on the drainage pipe at the bottom of the active iron purifier, and the flushing drainage pipe valve is connected with a flushing drainage pipe which is connected into a sludge well. The drainage system and the drainage method have the advantages that active iron and anaerobes are coupled to be in concerted reaction so as to degrade antibiotics in drained water of the culture pond; a bank slope is utilized fully, cost of capital construction is lowered, and the gravel bed and the bank slope subsurface wetland have good purification effect on outlet water.

Description

technical field [0001] The invention relates to an active iron purifier coupled with a bank slope wetland system to purify a breeding pond drainage system and a drainage method. It belongs to the field of drainage treatment of breeding ponds. Background technique [0002] Pond aquaculture is the most important aquaculture method in my country. With the increasing demand for aquatic products, intensive aquaculture is more and more used in pond aquaculture. Intensive aquaculture has unreasonable breeding capacity and nutrient supply and demand problems. High-density stocking, large feeding volume, a large amount of residual bait and animal metabolites remain in the aquaculture water body, resulting in eutrophication of the aquaculture water body. The eutrophication of aquaculture water will also accelerate the reproduction of pathogenic organisms and induce diseases. In order to prevent and control fish diseases, a large amount of disinfectants, antibiotics and insecticides ...

Problems solved by technology

However, powdery active iron particles are easy to passivate and harden, requiring frequent cleaning and replacement, which limits the wide application of active iron in water treatment
