Problems solved by technology

Due to the incomplete sewage treatment facilities in most areas, some sewage treatment is not up to standard or even discharged without treatment. At the same time, a large number of chemical products such as washing powder and detergent are used, causing pollutants to exceed the self-purification capacity of the water body and causing the water body to deteriorate. The phenomenon of eutrophication of water body appears, which destroys the water ecological environment
[0003] At present, according to the eutrophication sewage treatment technology, it can be divided into activated sludge method, anaerobic method, biofilm method, etc. These processes all have disadvantages: the activated sludge method occupies a large area, high energy consumption, and the amount of excess sludge produced Large, poor treatment effect on refractory organic sewage; the biom...

Embodiment Construction

[0019] A nutrient-rich water body purifier, prepared by the following method:

[0020] (1) Spray the bentonite with 8% sulfuric acid solution until it is wet, stir evenly, age for 6 hours, then send it to the rotary kiln for heating until the temperature is 300°C, take it out after 1 hour, cool it sharply with cold water, and then dry and pulverize it to obtain Activated bentonite powder for standby;

[0021] (2) Wash the old tea leaves, crush them to 50 mesh, and dry them until the water content is lower than 15%. Mix the obtained tea powder and chitosan at a mass ratio of 1:2 and treat them with ultrasound at 25kHz for 10 minutes. Disperse evenly, then heat to 60°C, and spray 0.1% 0.2mol / L sodium hydroxide solution according to the mass ratio at the same time, stir evenly to obtain the modified mixture for later use;

[0022] (3) Mix diethylene glycol and ethylene glycol at a volume ratio of 3:1, add ferric chloride with a total mass of 5% to the mixture, and stir continuou...

Abstract

The invention discloses an eutrophic water body purifier and a preparation method thereof. The eutrophic water body purifier is prepared by raw materials of bentonite, old tea leaves, chitosan, iron chloride, and an EM inocula. The purifier uses self adsorption characteristic, the composite microbe inocula uses self degraded characteristic, so that a pollution substance in eutrophication sewage can be effectively removed, nitrogen and phosphor compounds, and an organic matter in a water body can be rapidly decomposed, symbiosis synergism of a plurality of bacteria can be used, a stable aquaticecological system is generated, generation of harmful pathogen can be inhibited, aquatic organism having a purifying function in the water body is activated, and the water body is purified, the eutrophic sewage harmlessness and minimization are realized, and the eutrophic water body purifier has important environmental, social and economic benefits.

Description

technical field [0001] The invention relates to the technical field of water body improvement, in particular to a nutrient-rich water body purifier and a preparation method thereof. Background technique [0002] With the continuous development of urbanization in our country, organic sewage pollution has become one of the main reasons for the eutrophication of water sources in our country, which has seriously affected the ecological environment. The occurrence of eutrophication in water body is mainly caused by the increase of nutrients such as nitrogen and phosphorus in water. Due to the incomplete sewage treatment facilities in most areas, some sewage treatment is not up to standard or even discharged without treatment. At the same time, a large number of chemical products such as washing powder and detergent are used, causing pollutants to exceed the self-purification capacity of the water body and causing the water body to deteriorate. The phenomenon of eutrophication of...
