Embodiment 1

[0028] A method for killing cyanobacteria and purifying water, comprising the steps of:

[0029] Step (1), grow seedlings and cultivate Chinese herbal medicine according to the conventional method. When the seedlings are cultivated, they are transplanted to foam plastic plates and placed in the wetland around the water area to be treated for further cultivation, allowing their fibrous roots to absorb the nutrients in the wetland water; each foam The seedlings on the plastic plate are of a single species;

[0030] The Chinese herbal medicines include honeysuckle, golden buckwheat, isatidis, houttuynia cordata, centipede grass, garlic, calamus, leaf-eating grass and eupatorium adenophora;

[0031] According to the size of the seedlings, the foamed plastic plates are punched in an appropriate amount so that the roots of the seedlings can absorb the nutrients in the water; the frame made of bamboo around the foamed plastic plates is fixed, so that they can be fixed when they are c...

Abstract

The invention relates to a method for killing blue-green algae to purify water. The method specifically comprises the following steps: putting Chinese herbal medicine seedlings to a plurality of foam plastic board blocks and putting the foam plastic board blocks to a wet land around a to-be-governed water area to culture until the seedlings are 30-50cm high, transplanting the seedlings into the to-be-governed water area to continuously culture, crossing the foam plastic board blocks to form groups, and reserving a channel for allowing a boat to travel on a water surface between groups, wherein each group comprises the following Chinese herbal medicines in terms of parts of a cultivated area: 20-30 parts of honeysuckles, 10-20 parts of wild buckwheats, 10-20 parts of isatis roots, 5-10 parts of houttuynia cordata, 5-10 parts of ciliate desert-grass, 5-10 parts of garlic, 5-10 parts of calamus, 40-50 parts of clover and 50-60 parts of crofton weeds. In daily management, the Chinese herbal medicine seedlings are maintained at regular intervals, the steam leaves are pruned, the fertilizer is not applied and the pesticides are not applied. The method disclosed by the invention can be used for quickly damaging normal physiological metabolism of algae and forcing the algae to die, secondary pollution is avoided, the toxic or side effects are avoided, and the investment can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of water pollution control, and in particular relates to a method for purifying water by killing cyanobacteria. Background technique [0002] With the increasingly serious pollution of lakes, reservoirs, rivers and other waters and the frequent occurrence of blue-green algae, we are facing a major worldwide problem: how to control blue-green algae and purify water? [0003] Blue-green algae often multiply in large numbers in summer and form a green layer on the water surface. The smelly foam is called "water bloom", and large-scale blue-green algae outbreaks are called "green tide". Green tides cause water quality to deteriorate, and in severe cases deplete the oxygen in the water and cause fish to die. What's more serious is that some species of cyanobacteria, such as Microcystis, also produce microcystins (MCs for short), and about 50% of green tides contain a large amount of MCs. In addition to being di...
