Chinese flower lake cleaning method

Water flower garden filter

The flower gardens on the water make the Lake and Moon Lake - the ecological lungs of Wuhan City - look very romantic. But not only are they decorative objects, they also work to clean up the city's waste water into these lakes.

Chinese scientists have applied five integrated measures to protect the environment of the two lakes, suggesting their application to lakes in our country.

First: Using water to circulate through the filtration system is a flower garden. Specifically, water is pumped into a system of tubes with many small holes. The tubes are placed parallel to each other on a large lake but not very deep (later becoming flower gardens), in the pits filled with large and small stones. Planted in that kind of yellow and red flowers of canna family. This type of plant has long roots and is able to strongly absorb organic and inorganic substances contained in waste water. Water flowing down the hard ground will escape in one place and flow into an artificial stream before returning to the lake. This stream is beautifully designed.

It is also possible to grow a very fast growing grass and bloom very well in a certain season.

Second: Combined with the first measure, but only in the area of ​​soil covering the spraying pipes and on that soil planted ornamental plants with deep roots to clean up the water.

Third: Choose a corner of the lake to spread porous carpets floating on the surface with small holes in the above-mentioned flower tree and create a flower garden on the lake. Very beautiful blooming flowers and roots up to 60 cm deep should clean the lake water very quickly. Asked why not using water hyacinth, Chinese managers said that the type of duck grows too fast, occupies all the surface of the lake, there is no beautiful scenery and the boating area. Moreover, their roots are not long.

Fourth: Use a boat to drop the net and hire workers to drag to the shore of the fast-growing seaweed, filling up the water surface. This seaweed is transferred to fish feed or as fertilizer.

Fifth: Where the treated water, before flowing into a large lake, is concentrated in a small pond, treated with microbial inoculants to decompose the remaining organic matter and greatly reduce the The index of BOD, COD, NH3, NO2, NO3 . This way also solves the situation of flowering water, meaning that the micro-algae that meet many organic foods have grown too much on the water surface.
