Problems solved by technology

[0003] At present, there are many ways to control the eutrophication of lakes, mainly physical, chemical and ecological methods. Among them, physical methods include cutting off pollution sources, retention ponds, dilution, raising water levels, artificial circulation of lake water, dredging, etc. These methods are all There is a common disadvantage, that is, the cost is relatively high; chemical methods include sewage phosphorus removal, chemical phosphorus fixation, etc., but the effect of chemical methods is not obvious, and it is easy to cause new pollution

Embodiment

[0014] Embodiment: a kind of method with bitter grass control lake eutrophication is characterized in that it is made up of following steps:

[0015] ① Cultivate bitter grass; the cultivation conditions for the said bitter grass are: put bitter grass in a glass tank, add a certain amount of water, place a light source on the top of the tank, and light it for 10 hours a day. It takes a total of 5 days, and the water temperature is controlled at 18°C ;

[0016] ② Add the cultivated bitter grass to the bottom of the lake and adapt to it for 3 days;

[0017] ③ Afterwards, add chloroform, an algal growth inhibitor, 5% potassium persulfate, and 10% stannous chloride solution.

[0018] The addition of the above-mentioned chloroform as the protection agent of bitter grass can be 1 / 50th of the weight of bitter grass.

[0019] The above-mentioned add-on of 5% potassium persulfate as algae growth inhibitor is milliliter, and the add-on of said stannous chloride solution is 5 times of t...

Abstract

A method for using vallisneriaceae to treat the nutrients-enriched water in lake includes cultivating vallisneriaceae, adding it to lake bottom, making it adapt the lake water for 3-5 days, and adding vallisneriaceae protecting agent and seaweeds growth inhibitor.

Description

[0001] (1) Fields: [0002] The invention belongs to a method for controlling environmental pollution of lakes, in particular to a method for controlling eutrophication of lakes with bitter grass. (two) background technology: [0003] At present, there are many ways to control the eutrophication of lakes, mainly physical, chemical and ecological methods. Among them, physical methods include cutting off pollution sources, retention ponds, dilution, raising water levels, artificial circulation of lake water, dredging, etc. These methods are all There is a common disadvantage, that is, the high cost; chemical methods include sewage phosphorus removal, chemical phosphorus fixation, etc., but the effect of chemical methods is not obvious, and it is easy to cause new pollution. (3) Contents of the invention: [0004] The purpose of the present invention is to design a method for controlling lake eutrophication with Erythrina fragrans, so that it can overcome the shortcomings of th...
