Device for improving water quality of river bottom

Abstract

The invention discloses a device for improving the water quality of a river bottom. The device comprises a horizontal reaction tube placed at the river bottom and a cavity floating on the surface of the river, a storage battery is arranged in the cavity, the external of the cavity is fixedly provided with solar battery panels connected to the storage battery, and the outer wall of the reaction tube is provided with a heat insulation layer; the inner wall of the reaction tube is provided with a constant temperature heater connected with the storage battery, an anaerobic reaction section, a throat tube, an aerobic reaction section and electric blades are sequentially arranged in the reaction tube, the throat part of the throat tube is provided with an upward vertical thin tube, and the top end of the thin tube is located above the river surface; the upper part of the pipeline of the aerobic reaction section is provided with an opening connected with a vertically upward cylinder, the inside of the cylinder is a mirror surface, the top of the cylinder is a bell mouth, and the top large-mouth end cover of the bell mouth is provided with a convex lens; and the electric blades connected with the storage battery are arranged at the end part of the reaction tube. The device has a very good treatment effect on river pollutants, can continuously perform the treatment in an all-weather manner, and can realize the degradation of the entire river pollutants.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment in environmental protection, and particularly relates to a device for improving river bottom water quality. Background technique [0002] With the rapid development of my country's economy, my country's water environment problems have become increasingly prominent, and the urban and rural water environment has encountered unprecedented threats. The centralized treatment rate of urban wastewater in my country is only 13.4%. Compared with the wastewater treatment rate of 80%-90% in developed countries, the wastewater treatment rate in my country is extremely low. A large amount of untreated sewage is directly discharged into rivers, causing serious pollution of river water quality. Excessive application of chemical fertilizers and pesticides causes a large amount of chemical fertilizers and pesticides to flow into the river with precipitation or irrigation water, which has also become an im...
