Comprehensive treatment system for river

Abstract

The invention discloses a comprehensive treatment system for a river. The comprehensive treatment system comprises a slag retaining grid, riverbed wetland, a riverway contact oxidation component, an aquatic-plant filter bed, an aquatic-plant fixing zone and an aquatic-plant purification zone; wherein two ends of the slag retaining grid are erected on river banks located at sides of a riverway, andthe slag retaining grid is used for intercepting foreign matters on the surface of the river; the riverbed wetland is distributed on the river banks located at both sides of the river; the riverway contact oxidation component comprises an aeration and oxygenation part and a biofilm, the aeration and oxygenation part is arranged in the riverway for aeration and aeration, and the biofilm is fixed in the riverway; the aquatic-plant filter bed is arranged at a mixed water outlet of the riverway; and the aquatic-plant fixing zone and the aquatic-plant purification zone are arranged in the riverway. The comprehensive treatment system for the river has the advantages of a wide application scope and low treatment cost.

Description

technical field [0001] The invention relates to a comprehensive river channel management system. Background technique [0002] River management is the main content of eliminating black and odorous water bodies, and each river has different river management methods due to its geographical location, climate environment, hydrological conditions, topographical conditions, water quality, river bed revetment, etc. , which is commonly referred to as the need to formulate "one river, one policy". In the process of formulating "one river, one policy", it is necessary to carry out detailed investigation and analysis on the project river. The main problems faced by the river are: sewage outlet pollution, riverbed siltation, direct sewage drainage, garbage floating accumulation, non-point source pollution, revetment Damage, no ecosystem, weak supervision, etc., and the main measures for river management at this stage include: microbial preparations, aeration and oxygen enhancement, int...

Problems solved by technology

In the process of formulating "one river, one policy", it is necessary to carry out detailed investigation and analysis of the project river. The main problems faced by the river are: sewage outlet pollution, riverbed siltation, direct sewage drainage, garbage floating accumulation, non-point source pollution, revetment Damage, no ecosystem, weak supervision, etc., and the main measures for river management at this stage include: microbial preparations, aeration and oxygen enhancement, integrated equipment, aquatic plant systems, etc. The scope of application and cost of each technology vary greatly , and the main problems of each river course are not the same, which brings great difficulties to technicians when proposing corresponding control measures
