Reactor for removing nitrogen and phosphorus of lake and river water phase by biological and physical synergistic method

Abstract

The invention relates to a special reactor used for concentrating and removing nitrogen and phosphorous in a river or lake water phase. The reactor comprises four basic units, including a through-carved thin layer bracket, a flotation system, a plant setting system and a filling system. The four units are made up of (made of) physical materials and advanced plants, wherein, the through-carved thin layer bracket is made up of polypropylene or polyethylene plastic materials; the flotation system is made of spring steels, polypropylene and other plastic materials; the plant setting system consists of polystyrene foam materials and aquatic advanced plants or terraneous advanced plants; and the filling system consists of zeolite and limestone and polypropylene or polyethylene plastic materials. The reactor of the invention is designed to aim at the current situation that the nitrogen content and the phosphorous content in the most water phases are definitely high in spite of the forms of the pollution to the river or lake water phase. The reactor of the invention has the advantages that the reactor can overcome the defects existing in the technique of the same kind, improve the removal efficiency on the nitrogen and the phosphorous, be applicable to the river waters or the lake waters with the pollution in different levels and provide habitat conditions for the large multiplication of microorganisms to quicken the degradation of organic pollutants in the water phase.

Description

Technical field: [0001] The invention belongs to the field of resources and environment technology, and relates to a device specially used for enriching and removing nitrogen and phosphorus in the water phase of rivers and lakes, especially the filler and plant system therein. Background technique: [0002] In terms of nitrogen and phosphorus purification technologies in the water phase of rivers and lakes, according to their principles, they can be divided into three categories: physical methods, chemical methods, and biological / ecological methods. Among them, representative technologies mainly include sediment dredging, mechanical algae removal and ecological water transfer by physical methods; flocculation sedimentation and chemical algae removal by chemical methods; microbial enhanced purification and plant purification by biological / ecological methods. However, many years of research and application results at home and abroad show that the safe and effective direct remo...
