Rapid treatment apparatus and method for river sewage

Abstract

The invention discloses rapid treatment apparatus for river sewage. The apparatus comprises a rubber dam transversely arranged on a river channel, river water enters a reactor through a raising pipeline, and the river water raising pipeline is provided with a sulfuric acid adding device, a ferrous sulfate adding device and a hydrogen peroxide adding device in sequence; and hollow mesh-shaped partition layers are arranged in the reactor, an air distributing pipe is arranged below the hollow mesh-shaped partition layers, the air distributing pipe is connected with an aeration device, and a pureiron filler is arranged on each hollow mesh-shaped partition layer. According to the apparatus disclosed by the invention, a water level is raised through the rubber dam arranged on the river channel,a reaction is performed by using sulfuric acid, a reaction is performed by using ferrous sulfate, a reaction is performed by using hydrogen peroxide, the cleaned sewage enters the reactor, the pure iron filler in the reactor, sulfuric acid, ferrous sulfate and hydrogen peroxide are subjected to a weak hydroxyl reaction, oxygen is introduced though the aeration device, the sewage is subjected to aprimary battery reaction, the entire reaction process only takes only about 7-10 min, after the reaction is completed, the sewage enters a sedimentation tank, a micro amount of PAM solution is addedinto the sedimentation tank, and coagulation sedimentation is performed.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a rapid treatment device and method for river sewage. Background technique [0002] At present, there are two ways to control the heavy pollution of rivers in China. One is to sprinkle microbial agents in the rivers to decompose and digest the pollution in the water. However, due to biological uncertainty, there is no conclusion in China about the subsequent pollution of the rivers in the future. At the same time, due to Due to the perennial fluidity of the river, the microbial agent cannot effectively stay for a long time, resulting in a very low microbial degradation rate. At the same time, the investment cost is huge; the second is to sprinkle chemical agents and oxidants in the river to degrade organic pollutants. Due to the limitations of chemical agents, the pollutants can only be deposited at the relative temperature, and the pollutants that sink to the bottom of ...
