Embodiment 1

[0011] The water body in this embodiment is a natural lake with an area of ​​about 160 mu. The lake surface is flooded with blue-green algae, which causes sludge at the bottom of the lake to grow. The water body is treated with seaweed extract in order to reduce the silt content of the lake. The seaweed raw material of the seaweed extract is selected from kelp, and the seaweed extract is mixed with the water body in the form of a solution, that is, the seaweed extract solution is sprayed into the lake. The process of mixing the seaweed extract solution with the lake water is divided into two stages, and the spraying frequency of each stage is once a month; the first stage is a spraying concentration of 200ppm, and a total of one spraying; the second stage is a spraying concentration of 10ppm, A total of eleven sprays were made. In other embodiments, the mixing of the seaweed extract and the water body can be done in stages, and the spraying concentration and spraying frequenc...

Embodiment 2

[0016] The water body in this embodiment is a natural lake with an area of ​​about 3000 mu. The lake is a eutrophic water body, the content of ammonia nitrogen at the bottom of the lake is 2.3mg / L, the content of phosphorus is 0.34mg / L, and the content of orthophosphate is 0.295mg / L. The water body is treated with seaweed extract in order to reduce the nitrogen and phosphorus content of the lake. The seaweed raw material of the seaweed extract is selected from kelp and Ascophyllum nodosum, the mass composition is kelp:Ascophyllum nodosum=1:1, the seaweed extract solution is sprayed into the lake, the spraying concentration is 5ppm, and the spraying frequency is every 7 days once. Due to the low concentration of the seaweed extract used and the large area of ​​the lake, mechanical aeration is used for oxygenation. In other embodiments, the dissolved oxygen can also be kept above a certain concentration, such as 1 mg / L, by means of natural water drop aeration and oxygenation, ...

example 3

[0021] The water body in this embodiment is the water body in the domestic sewage treatment system, the treatment capacity of the domestic sewage treatment system is 40,000 tons / day, and the treatment process is the ordinary activated sludge process. The water body is treated with seaweed extract, and microorganisms are added at the same time, the purpose is to reduce the COD of the sewage effluent. The seaweed extract is selected from a mixture of kelp and kelp, and the mass composition is kelp: kelp = 4:1. The seaweed extract solution is sprayed into the aeration tank, the spraying concentration is 50ppm, and the spraying frequency is once every 15 days. The microorganisms put in are a mixture of photosynthetic bacteria, nitrogen cycle bacteria and phosphorus solubilizing bacteria, the ratio is 5:1:1, 5 kg is added every day, evenly sprinkled in the aeration tank, and put in continuously for 7 days. In other embodiments, the added concentration and frequency of microorganis...

Abstract

The invention discloses a water treatment method. The water treatment method comprises the following step of mixing a sea alga extract with a water body, wherein the sea algae extract is a solid mixture which is extracted by carrying out physical treatment and / or chemical treatment on sea algae; the physical treatment comprises the following steps of chopping, grinding and drying; the chemical treatment comprises the following steps of extracting, neutralizing, oxidizing and adsorbing; the sea algae contains at least one of kelps, sea-tangles, phaeophyta, sargassum, fucus vesiculosis, nori and agars. The sea alga extract and the water body are mixed so as to supply nutrition to microorganisms in the water body; the metabolism speed of corresponding specific flora in a water environment can be effectively improved and the growth is promoted; the rapid propagation of the specific flora snatch limited nutrient substances in the water body so as to inhibit the growth of other floras or algae to inhibit the relative harmful biological accumulation and improve the self purification capability of the water body.

Description

technical field [0001] The invention relates to a water treatment method. Background technique [0002] In water treatment methods, the technical measures of biological regulation and bioremediation refer to the transfer, transformation and degradation of pollutants in water by using the life activities of cultivated plants or cultivated and inoculated organisms or microorganisms, so as to purify the water body. Biological regulation reduces algae biomass by rebuilding biological communities (including plant communities and animal communities), keeps water quality clear and improves biodiversity, mainly including biological regulation with aquatic plants as the main body and fish and zooplankton as the main body. The current problem of aquatic plants is that it is difficult to plant aquatic plants on water bodies with algae blooms. In addition, the ecological effects of newly introduced plants should be carefully evaluated. Zooplankton and some algae-eating fish can control...
