example 1

[0019] Example 1: Treatment of eutrophic water body in a lake in the north

[0020] Such as figure 1 and figure 2 As shown, the method is provided with a water treatment zone 4, a water treatment zone 5, a water treatment zone 6, a water treatment zone 7 and a matrix treatment zone 10, and the substrate treatment zone 10 is located at the water outlet 2 of the water treatment zone 7; Each water treatment area is provided with a water distribution ditch 3, and the water distribution ditch 3 is located at the front end of each water treatment area; a water receiving port 9 is set between the second water treatment area 5 and the third water treatment area 6, and the first water treatment area 4 and the second water treatment area Aqueducts 8 are set between areas 5 and between the third water treatment area 6 and the fourth water treatment area 7; cultivated soil 12 is arranged on the surface of each water treatment area, and plants 11 are planted on the cultivated soil 12; en...

[0027] Example 2: Treatment of eutrophic water body in a river in the north

[0028] Such as figure 1 and figure 2 As shown, the system is constructed, and the water flow per minute of the water inlet 1 is 15% of the capacity of the water distribution ditch 3. When the maximum depth of the water in the water treatment area 4 reaches 220mm, the water supply is stopped, and after 24 hours, the water passage 8 is opened. The water in the first water treatment area 4 enters the second water treatment area (5), and after an interval of 26 hours, the first water treatment area 4 continues to enter the water.

[0029] After maintaining the water in the second water treatment area 5 for 24 hours, open the water receiving port 9, and the water enters the third water treatment area 6, and after maintaining for 24 hours, open the water passage 8 between the third water treatment area 6 and the fourth water treatment area 7, and the water After entering the fourth water treatment area ...

Abstract

The invention discloses a method for eutrophication control and resource utilization of northern surface water bodies. The method is set up with a water treatment zone (4), a water treatment zone two (5), a water treatment zone three (6), a water treatment zone Four districts (7) and substrate treatment district (10), substrate treatment district (10) is positioned at the water outlet (2) of water treatment four districts (7); Substrate treatment district (10) arranges sandstone material and active carbon mixed matrix, realizes tailing End-to-end high-efficiency purification; cultivated soil (12) is arranged on the surface of each water treatment area, and plants (11) are planted on the cultivated soil (12); the water entering the system from the water inlet (1) passes through each water treatment area and substrate treatment in turn After zone (10), it is discharged from the water outlet (2). When the mixed substrate is out of operation in winter, the substrate is sieved, and the removed activated carbon is used to prepare organic fertilizer. The method has good purification effect and obtains biomass value at the same time.

Description

technical field [0001] The invention relates to the technical field of environmental ecological energy in environmental science and engineering, in particular to a method for eutrophication control and resource utilization of northern surface water bodies. Background technique [0002] In recent years, due to the abuse of farmland chemical fertilizers and pesticides and the arbitrary stacking of livestock manure and straw, these pollutants are brought into the river during rainfall, causing serious eutrophication of the river. Due to the large volume of surface water, the cost of traditional water treatment methods high. The current floating bed technology has achieved certain results, but the overall temperature in the northern region is low and the plant growth cycle is short. Therefore, the application of the floating bed technology is subject to certain restrictions. The combination of water eutrophication control and resource utilization can effectively reduce operatin...
