Technology principle:

WEP water environment restoration system is to fll the closed water body with high eficiency dissolved oxygen intermittently through deep aeration, so as to increase the concentration of dissolved oxygen in the 1km radius area, so as to improve the; anoxic state of water body well and realize water quality protection and restoration.

Technical and economic indicators and characteristics:

1. Improve water quality: Improve water quality from five categories to at least three categories of water standards.

2. DO value increases significantly: from0.5 to 5.

3. Improve the bottom mud: the bottom mud is dark brown and has a fishy smell. After operation and repair, the bottom mudtums yellow and microorganisms return.

4. In terms of meeting the environmental standards of surface water source, among the 7 measured items, four items, such as concentration of dissolved oxygen (DO), total phosphorus, COD (Cr) and iron (Fe), meet the class 3 water environmental standards.

5.Energy saving: low operating cost, environmental protection and energy saving.

Technical advantages:

1. The process mainly increases the dissolved oxygen at the bottom of the water body by inputting high concentration of dissolved oxygen into the water body, thus improving the overall environment at the bottom of the water body.

2.establish automatic monitoring, data transmission, remote control system, improve the level of automatic control.

3.in a unique gas-liquid mixing way, so that the oxygenation process does not produce bubbles, does not roll the bottom mud, does not change the state of water stratification, will not destroy the upper ecosystem.

4.simple structure and easy maintenance, because there is no need for pressure control system, so that its structure is simple, that is, easy maintenance and operation, and reduce the occurrence of failure; Only the water pump shall be maintained for equipment in water.

Scope of application:

Water environment restoration of closed and semi-closed water areas such as reservoirs, lakes and bays.
