Example Embodiment

[0049] The invention also discloses a preparation method of environmental protection enzyme, which includes the following steps:

[0050] Put fruits and / or vegetables, water and sugars in a closed container in proportion to ferment for 3-6 months, and filter the filtered clear liquid to obtain the environmentally friendly enzyme.

[0051] Among them, the fermentation raw material may only contain fruits and not vegetables; for example, 1 / 3 apple peel, 1 / 3 banana peel and 1 / 3 orange peel are preferred. The fermentation raw material may also contain only vegetables and not fruits; for example, 1 / 3 lettuce, 1 / 3 cabbage and 1 / 3 water spinach are preferred.

[0052] Among them, the environmental protection enzyme is mixed and fermented according to the volume ratio of fruits and / or vegetables: water: sugar=1:2-4:8-12.

[0053] The invention also discloses a preparation method of the algal bloom inhibitor, which comprises the following steps:

[0122] Example 2 Inhibition of environmental protection enzymes on the growth of Scenedesmus tetracera and improvement of water quality

[0123] Add the prepared environmentally friendly enzymes dropwise to the Scenedesmus tetracervus culture solution and set a blank control, three in parallel for each group.

[0124] On the 3rd day of the experiment, adding 1:240, 1:120 and 1:60 concentration of the algae broth cultured with environmentally friendly enzymes, it was obvious that Scenedesmus quadrifolium flocculated and precipitated to the bottom of the culture medium, and the higher the concentration of enzyme added in the culture medium , The smaller the amount of Scenedesmus quadrifolium flocculated. The water in the upper part of the algae culture medium with the environmental protection enzyme concentration of 1:240 becomes clear and transparent; the algae culture medium with the environmental protection enzyme concentration of 1:120 and 1:60 has the color of the enzyme itself ...

Abstract

A preparation method for garbage enzyme comprises the following steps: putting fruits and/or vegetable, as well as water and saccharides into a closed container according to a ratio, fermenting for 3 to 6 moths, filtering, and taking clear liquid after the filtering, thus obtaining the garbage enzyme, wherein the garbage enzyme is formed by mixing and fermenting according to the volume ratio that the fruits and/or the vegetables : the water : the saccharides is equal to 1: (2 to 4) : (8 to 12). A preparation method for an algal bloom inhibitor comprises the following step: adding water to dilute the garbage enzyme prepared by the preparation method for the garbage enzyme, thus obtaining the algal bloom inhibitor. The algal bloom inhibitor has a remarkable effect of inhibiting alga growth, contributes to aquatic ecological environment purification and water body self-recovery, and has a perfect improving effect on water quality; the preparation methods for the garbage enzyme and the algal bloom inhibitor are simple, low in cost, easy for industrialized operation, and capable of avoiding secondary pollution.

Description

technical field [0001] The invention relates to the field of ecological restoration of water body environment, and more specifically relates to a preparation method of an environmental protection enzyme and an algal bloom inhibitor. Background technique [0002] Lakes are the main source of water for agriculture, aquaculture, and domestic use. They also have the functions of maintaining biodiversity, regulating climate, storing floods, regulating surface runoff, and purifying water quality. With the rapid development of my country's economy, the urban population continues to increase, the discharge of industrial and agricultural wastewater and domestic sewage continues to increase, a large amount of nutrients continue to enter the lake, the proportion of eutrophic lakes increases year by year, and the abnormal proliferation of algae occurs frequently, forming water blooms . The dominant algae of lake water blooms are generally cyanobacteria, green algae and diatoms, among wh...
