Abstract

The invention discloses strain reproduction spreading equipment for the contamination control of a river. A base frame and a strain reproduction bracket are arranged at the bottom of the river and in water respectively, and can be arranged along the whole section of the river without hindrance to the navigation of ships, so that a primary flow area on the middle part of the river is effectively controlled, and contamination control effects are improved; in addition, the strain reproduction bracket is driven by a rocker arm to swing, so that the relative positions of a biofilm carrier and an aeration point can be changed to disturb bubbles produced by an aeration device by the biofilm carrier swinging along with the strain reproduction bracket in a floating process to form strong disorder and enhance oxygen dissolution effects and to make the oxygen content distribution of the water uniform to improve the production of decontamination strains and decontamination effects, and contamination control strains growing on the biofilm carrier easily and continuously fall off from the biofilm carrier and are spread in the water in a process of swinging along with the biofilm carrier, and are scattered towards a downstream water body under the coaction of the bubbles and water flow to improve the contamination control effects.

Description

technical field

[0001] The invention relates to river pollution control equipment, in particular to a strain breeding and spreading equipment for river pollution control. Background technique

[0002] Serious water pollution is unavoidable for urban rivers with small flow rates and incomplete interception of sewage. In order to control river water pollution, biological pollution control methods represented by artificial microbial floating island technology have been widely used in recent years. In this method, the biofilm carrier is floated on the water surface, and the aeration device fixed under the carrier is used for aeration and oxygenation. , so as to promote the reproduction of bacteria (microorganisms) on the biofilm in the water to absorb and transform pollutants, thereby improving water quality, but this biological pollution control method has the following shortcomings: 1. The relative relationship between the aeration point and the carrier The position is basic...
