Problems solved by technology

However, those skilled in the art believe that it is theoretically feasible to control algae-containing sewage by inhibiting algae, but how to transform the theory into an operable technology still needs to be developed and discussed by technical personnel.

Embodiment 1

[0013] Example 1, a landscape pool of about 1,000 cubic meters in a community is treated. Due to poor management, the landscape water has serious algae growth, and its own ecology has basically been destroyed, and there is no self-repair ability. We use the method of comprehensively controlling the eutrophication of the water body by inhibiting algae insects, select algae inhibition (algae inhibition), and put them in water for breeding. During breeding, 20-30 days, put blue-green algae powder or fence within 0-20 days For algae (10-100 grams per liter of water) and chlorella, the dosage is increased by 5-10% per day, and the dosage remains stable within 20-30 days. At this time, the number and vitality of algae-inhibiting insects are optimal Then take the sewage sample of the water area to be treated, and then put the algae-inhibiting insect with stable growth into the sewage sample. After 2-3 days of adaptation and elimination process, measure the density of the insect body, ...

Abstract

The invention relates to a water treatment technology of rivers, lakes and landscapes, in particular to a comprehensive treatment method of water eutrophication by anti-algae insects, which solves the problem of algae pollution of landscape water. The method comprises the following steps: selecting the anti-algae insects and then placing in water for raising; taking a sewage sample from a water area to be treated; throwing the anti-algae insects which grow stably into the sewage sample, adaptively screening, and then throwing the selected anti-algae insects into the water according to the standard that the first throwing quantity in the transformed water is not less than 1*105-2*105 / m<3>; according to the effect of eliminating algae in the water, throwing the anti-algae insects for the second time; after the water is improved, implanting submerged plants into the water; and after the submerged plants grow and reproduce, throwing a certain amount of aquatic organisms such as fish, shrimp and the like into the water to form a complete underwater ecosystem. The method of the invention hits the key technical point of water treatment by the anti-algae insects, thus achieving good initial effect and faster effect and speed of removing the algae; and the transparency of the water is rapidly improved, which is beneficial to growth of waterweeds.

Description

technical field [0001] The invention relates to a river course, lake and landscape water treatment technology, in particular to a method for comprehensive treatment of water eutrophication by using algae inhibition. Background technique [0002] Cyclops: As a kind of large daphnia, Cyclops is a filter-feeding cladocera, which is a domesticated zooplankton. [0003] It grows and reproduces in the environment. The original purpose is in the direction of aquaculture. After continuous domestication and rejuvenation, the adaptability and treatment ability of the domesticated algae-infected insects in polluted water bodies are further enhanced. In recent years, large-scale algae outbreaks have often occurred in rivers, lakes and seas in my country. The massive reproduction of algae has seriously damaged the balance and stability of the aquatic ecosystem, affecting the water supply of water sources, water body landscape, the development of aquaculture, and the development of algae ...
