Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Such as figure 1 with figure 2 Commonly shown, a method for suppressing saltiness by air bubbles at the estuary of a river, laying several hoses 3 in the river channel, the hoses 3 usually choose plastic pipes or rubber hoses, and the hoses 3 extend along the surface of the embankment 1 and the surface of the riverbed 2, and The extension direction of the hose 3 is perpendicular to the water flow direction of the river, and the two ends of the hose 3 are fixed. When fixed, the hose 3 at the corner uses the pipe clamp 5 to achieve a smooth transition, and no right-angle bending is allowed to affect the airflow. For smooth transportation, lay piles on the riverbed 2 close to the embankment 1, and then fix the pipe collars 5 on the piles, and the hose 3 on the surface of the riverbed 2 and between the two pipe collars 5 should be relatively loose,...

Abstract

The invention discloses the river estuary bubble salinity restraining technology and belongs to the technical field of environment friendliness and water quality guarantees. Multiple hoses are laid in a river way and extend along the surface of a dam and the surface of a river bed, the extending direction of the hoses is perpendicular to the flowing direction of a river, the two ends of each hose are fixed, one end of each hose is plugged, the other end of each hose is connected with a main air inlet pipe, the main air inlet pipe is connected with an air blower, and multiple air holes are formed in the positions, located on the river bed, of the hoses. When the river estuary bubble salinity restraining technology is used, bubbles floating from the bottom of the river are generated through air blown through the air blower through the air holes, river section stratified flow mixture is accelerated, and salt water wedges are prevented from being transmitted to the upstream. The river estuary bubble salinity restraining technology is convenient to implement, operation is simple, salt tide upstream tracing is effectively restrained, and the technology is widely applied to river ways along the sea.

Description

technical field [0001] The invention relates to the technical field of environmental protection and water quality assurance, in particular to a method for suppressing salinity by air bubbles at river estuaries. Background technique [0002] The estuary area is the area where salt and fresh water are mixed, and the radial and tidal forces meet. Due to the difference in density, the water flow has obvious stratification. As the rising tide goes up along the bottom, its interface slopes upstream and dives in a wedge shape, so it is called a saltwater wedge. Due to the intrusion of the salt water wedge, super-standard salt water appeared at the intake of the water plant in the upper reaches of the river, making it impossible for the water plant to obtain fresh water, which affected the safety of the city's water supply. In the past 10 years, salt tide activities in the Pearl River estuary have become more frequent, the scope of influence has become larger and longer, and the du...
