Embodiment 1

[0019] refer to figure 1 , a device for purifying river / lake water pollution, mainly composed of a floating body 1 provided with a strain material pool 5, a slow-release strain tube 2 and a grass rope carrier 7, the floating body 1 is arranged on the water surface, and the slow-release strain tube 2 is arranged below the floating body 1, communicated with the strain material tank 5 through a pipeline, and the slow-release strain pipe 2 is provided with a through hole, and the grass rope carrier 7 is inserted into the through hole and hung under the slow-release strain pipe 2.

[0020] The floating body 1 is composed of four plastic pipes with closed ends and a diameter of 10-25 cm connected with the first three-way pipe 3 arranged at the two ends of each pipe, and the adjacent first three-way pipes 3 are connected , form the strain material pool 5, the mouth of the through pipe facing up to the first three-way pipe 3 of each root is the feed inlet, and a through hole is provid...

Embodiment 2

[0027] The beneficial bacteria described in the method for purifying water pollution with the device is composed of the following raw materials in weight percentage: 25% denitrifying bacteria, 6% sulfurizing bacteria, 6% nitrosifying bacteria, 30% nitrifying bacteria, phosphorus accumulating bacteria 23%, Bacillus 3%, Bacillus subtilis 2%, Rhodopseudomonas palustris 5%. All the other are with embodiment 1.

Embodiment 3

[0029] The beneficial bacteria are composed of the following raw materials in weight percentage: 32% of denitrifying bacteria, 5% of sulfurizing bacteria, 4% of nitrosifying bacteria, 20% of nitrifying bacteria, 20% of phosphorus accumulating bacteria, 7% of bacillus, 7% of bacillus subtilis 5%, Rhodopseudomonas palustris 7%. All the other are with embodiment 1.

[0030] It is proved by experiments that the effect of using the device of the invention to purify river and lake water pollution is obvious.

[0031] The following table is a comparison table of the absorption of nitrogen and phosphorus in water bodies with different pollution degrees using the device and method of the present invention:

Abstract

The invention discloses a device for purifying river / lake water pollution. The device is mainly composed of a floating body with a strain material pool, a slow release strain pipe and a straw rope carrier, wherein the floating body is arranged on the water surface; the slow release strain pipe is arranged below the floating body and is communicated with the strain material pool via a pipeline; the slow release strain pipe is provided with a through hole; and the straw rope carrier is plugged into the through hole to be hung below the slow release strain pipe. The method for purifying water pollution by adopting the device comprises the following steps: firstly, putting the device into river or lake water to be purified; adding the prepared beneficial strain into the strain material pool in the device; and continuously conveying into the water in due time via the slow release strain pipe and the straw rope carrier to form a algae-strain symbiosis environment so as to degrade pollutantsin water. The device for purifying river / lake water pollution is simple to manufacture, has low cost and has obvious effect on purifying rivers and lake water pollution.

Description

technical field [0001] The invention relates to the treatment of water pollution, in particular to a device and method for purifying river / lake water pollution. Background technique [0002] The main cause of water pollution in rivers / lakes is that the nitrogen and phosphorus in the water seriously exceed the standard, and the excess of nitrogen and phosphorus leads to the growth of blue-green algae in lakes and rivers, the dissolved oxygen in the water drops sharply, the water stinks, and the eutrophication of the water is formed. Generally, about half of the nitrogen fertilizer applied to farmland is unused and flows into groundwater or ponds and lakes. A large amount of domestic sewage often makes the water body too fertilized. Relying on natural purification methods alone can no longer withstand the intrusion of a large amount of pollutants. Traditional methods are also unable to systematically treat large areas of water. Contents of the invention [0003] The object...
