Natural traditional Chinese herbal medicine capable of inhibiting and touching out cyanobacterial bloom

Abstract

The invention discloses a natural traditional Chinese herbal medicine capable of inhibiting and touching out cyanobacterial bloom. The natural traditional Chinese herbal medicine comprises the following components in percentage by weight: 10 to 30 percent of coptis chinensis, 10 to 25 percent of radix bupleuri, 5 to 20 percent of rheum officinale, 5 to 15 percent of schisandra chinensis, 5 to 15 percent of kaladana, 5 to 15 percent of sow thistle, 5 to 10 percent of spina gleditsiae, 3 to 8 percent of humifuse euphorbia herb, 4 to 6 percent of ginkgo leaves, 2 to 5 percent of lotus leaves and2 to 5 percent of little groundcherry herb fruit. The natural traditional Chinese herbal medicine is prepared by the following steps: selecting, cleaning and sterilizing the above traditional Chineseherbal medicine raw materials, weighing the traditional Chinese herbal medicine raw materials according to the percentage by weight, drying, chopping and mixing uniformly; adding water to soak, performing heating reflux and taking filtrate; and adding water and performing heating reflux again, discarding residues and taking the filtrate, and mixing the twice filtrate to prepare the traditional Chinese herbal medicine. The principle that plant secondary metabolites (allelopathic chemicals) have remarkable allelopathic inhibition and touch-out effects on algae is utilized, and various traditional Chinese herbal medicines are combined according to the traditional Chinese medicine combination principle, so that the effects of performing low-concentration synergistic inhibition and touch-out onthe algae by the allelopathic chemicals are achieved, and the advantages of high alga inhibiting speed, safety, no toxicity and the like are achieved.

Description

Technical field: [0001] The invention relates to the field of water ecological control and environmental protection, in particular to a natural Chinese herbal medicine capable of inhibiting and contact-killing cyanobacteria blooms and a preparation method thereof. Background technique: [0002] In recent years, with the continuous development of urbanization in my country, the discharge of industrial, agricultural and domestic sewage has increased rapidly, and a large amount of sewage containing N and P has entered the water environment. The growth, reproduction and outbreak of cyanobacteria are the process of N and P enrichment and conversion. , has no pollution to water bodies, and basically does not release algae toxins. However, after its death, the N, P, organic matter and algae toxins contained in it will be released into the water body and sediment, becoming the main endogenous pollution of rivers and lakes. Under aerobic and anaerobic conditions, aerobic microorganis...

Problems solved by technology

Although the effect is quick, the indicators do not cure the root cause, and a lot of manpower, material and financial resources are needed

2. Chemical method: Chemical algae removal is to control the reproduction of algae in water through chemical agents. Chemical algicides can achieve better short-term results in controlling the outbreak of cyanobacteria, but it does not reduce the basic amount of "nutrition" in the water body. In the past, blue-green algae will break out again, and the symptoms will not be cured, and the risk of secondary pollution will also be borne
