Description

A mobile solar aeration system for river management

technical field

The invention relates to the technical field of slow-flow water body treatment, in particular to a mobile solar aeration system for river channel regulation.

Background technique

Water resources are the foundation of social development and an essential resource for economic development. The phenomenon of water pollution and the protection of water resources have become one of the strategic issues of common concern in our country and even in the world. With the continuous progress of our society, the industry has developed rapidly, but a large amount of industrial wastewater is discharged in the process of industrial production, which has caused serious pollution to the water resources and environment of our country. According to the 2016 China Environmental Quality Announcement issued by the National Environmental Protection Administration, among the 411 selected surface water testing sections, only 41% of the sections meet Class I-III, 32% meet Class IV-V, and the sections with water quality inferior to Class V up to 27%, indicating that 59% of the river sections are not suitable for drinking water sources. Compared with rivers, lakes and reservoirs are more polluted. In 2005 alone, there were 21 major cities in the country with increasing groundwater pollution, 14 cities with less pollution, and 123 cities with basically stable groundwater quality, which shows that groundwater pollution should be taken seriously. Pollution of rivers, lakes and groundwater directly affects drinking water sources. Therefore, the management of lakes and rivers in cities is one of the main issues that are receiving increasing attention.

In some slow-flowing water bodies such as lakes, reservoirs, bays, estuaries, and river courses, due to the large accumulation of plant nutrients such as nitrogen and phosphorus, it is easy to cause aquatic organisms, especially algae, to multiply excessively, and it is easy to cause eutrophication of the water body. The eutrophication of the water body leads to an abnormal increase in the primary productivity of the water body, resulting in a decrease in the transparency of the water body, a decrease in the concentration of dissolved oxygen, a large number of aquatic organisms die, and the smell is unpleasant. Although rivers have a certain self-purification ability under natural conditions, the self-purification process of natural reoxygenation alone is very slow, and the dissolved oxygen in eutrophic water cannot meet the oxygen required by microorganisms to decompose organic matter during the self-purification process. Therefore, the dissolved oxygen concentration is an important parameter to measure the water quality of the water body.

At present, my country's treatment technologies for polluted lakes and rivers are mainly based on the following six aspects: Dissolved oxygen concentration control; light intensity control; vertical blend control; Nutrient control of rivers entering lakes; fish population control; Ecological control of the lakeside zone, among which, the control of dissolved oxygen concentration is a commonly used method for river channel management. At present, according to the principle of dissolved oxygen control in my country, the aeration technology that is widely used in river management is artificial aeration, which realizes the complete mixing of gas and liquid through plug flow and aeration and oxygenation, but artificial aeration requires manual operation and energy consumption.
