Preparation method and application of radix dichroae water bloom algae seed growth inhibitor

Abstract

The invention relates to a preparation method of a radix dichroae water bloom algae seed growth inhibitor. Radix dichroae which is a terrestrial plant Chinese medicinal herb is extracted in a water bath under the condition of 100 DEG C. The method specifically comprises the following steps of: putting the terrestrial plant Chinese medicinal herb radix dichroae in water, wherein the proportion of the radix dichroae to the water is 1g / 20ml; repeatedly extracting for four times in a boiling water bath at 100 DEG C for 0.5h each time; and filtering, concentrating and drying collected extracted liquid to prepare the inhibitor. The radix dichroae water bloom algae seed growth inhibitor can be used for inhibiting the growth of water bloom algae seed microcystis aeruginosa. The preparation methodhas the advantages that the terrestrial plant Chinese medicinal herb having wide source and low price is used as a raw material; the extracting process flow is simple, direct and economical; a higheralgae inhibiting effect can be achieved within shorter time under the condition of lower treatment cost, and the algae inhibiting effect is persistent and stable; and the preparation method does not use any chemical additive in the extracting process and cannot bring secondary pollutions to the water environment.

Description

technical field [0001] The invention relates to a treatment technology for algae pollution in water bodies, in particular to a preparation method and application of a growth inhibitor for algal blooms in Huangchang Mountain. Background technique [0002] A large number of algae blooms in water bodies, also known as "algae blooms", are a direct manifestation of the imbalance of water body ecosystems. In recent years, the eutrophication of water bodies mainly in Taihu Lake has caused a large number of blue-green algae outbreaks, which has attracted widespread attention from the whole society. Algae blooms in the water body lead to water pollution and the death of fish and shrimp, and the toxins released by some algae can directly endanger human health. Preventing algal blooms is an important part of promoting the balance and stability of freshwater ecosystems, and it is also the basis for protecting the harmonious coexistence of human beings and the environment. [0003] The...

Problems solved by technology

[0003] There are two main methods of controlling algae pollution in existing water bodies: one is chemical reagent treatment method, that is, chemical reagents with bactericidal and disinfection functions are used to control algae pollution, but all kinds of chemical reagents used in this method are The use of industrially prepared reagents will cause secondary chemical pollution that is extremely difficult to repair to the water body ecosystem, so it will bring great difficulties to the follow-up work of overall environmental protection; the other is the treatment method of aquatic plants, that is, using allelopathic Based on the principle, the allelochemical substances released by living aquatic plants to the surrounding aquatic environment are used to inhibit the growth of algae. Waters are limited
