Problems solved by technology
[0007] Although the efficiency of chemical phosphorus removal is high, its use is limited due to the high cost and the possibility of secondary pollution
Biological methods have significant effects in beautifying water landscapes, purifying water quality, and maintaining nutrient balance and ecological balance. However, aquatic plants in rivers and lakes face the possibility of freezing and dying in winter, which is greatly affected by water temperature seasons.
The comprehensive method of treating rivers and lakes such as ecological wetlands occupies a large area and is not easy to promote and use

Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings.
[0031] Such as Figure 1~Figure 4 As shown, a device for improving the water quality of rivers and lakes with columnar activated carbon is characterized in that: it comprises: a hollow columnar activated carbon 1, a plurality of fixed ropes 3 are penetrated into a plurality of columnar activated carbons 1 and then fixed in parallel on the ring support 2 and form a circular activated carbon surface, the ring support 2 is fixed with a counterweight 5 and a number of suspension balls 4 .
[0032] The fixed rope 3 includes hemp rope.
[0033] The ring bracket 2 includes a stainless steel ring.
[0034] The suspension balls 4 are evenly distributed on the ring support 2, and the number of the suspension balls 4 is four.
[0035] The counterweight 5 includes a fir cage, and stones 6 are arranged in the fir cage.
[0036] Described fir cage is made of fir bar 7.

The invention discloses a device and a method for improving the water quality of a river and a lake by using cylindrical activated carbons. The device is characterized by comprising hollow cylindrical activated carbons (1); a plurality of fixing ropes (3) penetrate into the multiple cylindrical activated carbons (1), are then fixed on a circular support (2) and form a circular activated carbon surface; a balance weight (5) and a plurality of suspended balls (4) are fixed on the circular support (2). According to the device and the method improving the water quality of the river and the lake by using the cylindrical activated carbons, provided by the invention, the influence from water temperature, water quality and water volume is less; materials are easily obtained and are low in cost; the device can be popularized and used in four seasons, is large in adsorption area, small in occupied area, free from causing secondary pollution, easy to move, and free from influencing the ship traffic or being clamped into corners of the river and lake; in addition, planktons can attach the device to grow, so that later-stage fishing disposal is facilitated; in addition, illumination time is greatly shortened, so that algae growth is inhibited to a certain degree.
Description
technical field [0001] The invention relates to a device and method for improving the water quality of rivers and lakes by using columnar activated carbon, belonging to the technical field of water treatment. Background technique [0002] With the continuous development of the economy and the acceleration of urbanization, a large number of untreated or substandard urban domestic sewage and industrial wastewater flow into rivers and lakes, coupled with the existence of agricultural non-point source and urban non-point source pollution, making lakes and rivers Nutrients such as nitrogen and phosphorus are continuously accumulated, leading to the accelerated development of eutrophication in water bodies. Most lakes in my country are plain or plateau freshwater lakes, and eutrophication has appeared to varying degrees. The technical approach for the prevention and control of eutrophication in lakes and reservoirs is to reduce the water body pollutants, especially the nutrient c...
