Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing;

[0024] Such as figure 1 As shown, the application of membrane treatment and oxygen-enriching device for black and odorous river treatment system, the sewage is sequentially processed through sewage pretreatment, facultative pond sedimentation, integrated membrane processor treatment, and after the sewage enters the flowing river, it is treated by high-concentration aeration device. Reaction treatment of black and odorous substances: Among them,

[0025] S1: Sewage pretreatment: One or more grooves 1 are set at the end of the sewage entering the river, and sand and gravel layers 2 are laid layer by layer on the bottom surface of the water outlet of the groove 1; The pollutants are partially precipitated; the surface of the sand layer 2 will form a natural biofilm system to remove the organic matter in the sewage;

[0026] S2: Settlement in the aerobic pond: Excavate the ae...

Abstract

The invention relates to a system for treating black-odor rivers by using membrane treatment and an oxygen enrichment device and belongs to the technical field of river treatment. According to the system for treating black-odor rivers by using membrane treatment and the oxygen enrichment device, the sewage is successively subjected to sewage pretreatment, precipitation via an anoxic pond and treatment via an integrated membrane treatment device; the reaction treatment of black-odor materials of the rivers is carried out by a high-concentration aeration device after the sewage enters the flowing rivers, so that the purpose of sewage treatment can be achieved. Through the system, the overall water environment capacity can be obviously improved; the water self-purification capability is achieved; the effect is very good; and the treatment cost of the black-odor rivers can be reduced.

Description

technical field [0001] The invention relates to river treatment technology, in particular to a system for treating black and odorous rivers using membrane treatment and oxygen-enriching devices. Background technique [0002] As the lifeblood of cities, urban rivers not only perform functions such as water circulation, soil and water conservation, water storage and flood control, and water quality conservation, but also regulate temperature and humidity and improve urban climate. A healthy urban water environment is an important guarantee for sustainable urban development. With the continuous acceleration of urbanization and industrialization, the pressure on urban river ecosystems has been increasing in recent years. The problems of water quality pollution and ecological degradation in many urban rivers in my country are very prominent, and even seasonal or perennial water blackouts have appeared. Smelly phenomenon. Water pollution has become one of the most important enviro...
