Abstract

The invention discloses a method for comprehensive treatment of a town river way. The method comprises exogenous pollution control: sewage draining outlet pretreatment and branch surge pretreatment; endogenous pollution removal: bottom mud pollutant treatment and biological purification of polluted water; in-situ remediation of a river channel ecological system: ecological restoration of aquatic plants and restoration of aquatic animals; and supplemented feeding of an efficient microbial agent and ecological restoration monitoring of the river channel. A staged treatment principle is adopted for the method for comprehensive treatment of the town river way, conditions are created positively to gradually reduce river channel pollution; through the exogenous pollution control, the endogenous pollution removal, the in-situ remediation of the river channel ecological system, later period maintenance and ecological regulation and the like, a water system is made smooth, the river channel is made clean, the ecological system is established artificially, the self-cleaning capacity of the river channel is restored gradually, healthy water circulation of the river channel is achieved, biodiversity is promoted, and virtuous circle of the town and country environment and the ecological system is promoted.
