Preparation process of freshwater macrofilamentous green algae module for eutrophic water purification

Abstract

The invention discloses a preparation process for freshwater large-scale filamentous green algae modules used for purification of eutrophic water bodies. The large-scale filamentous green algae modules are composed of a plurality of large-scale filamentous green algae module units. The preparation process includes: Step 1, Take river water to prepare standby water; Step 2, select Cladophora, after purification, put it in a refrigerator at 4°C for 1 to 2 days in the dark; Step 3, put the large filamentous green algae module unit into the seedling pool; Step 4, Take out the algae and cut them into segments and pour them into the seedling pool; step 5, after the spores or gametes of Cladophora reach the preset number of attachments, move the large filamentous green algae module unit to the nursery pool for cultivation; step 6, place the seedlings A plurality of large filamentous green algae module units are connected in series to form a large filamentous green algae module. The preparation process of the present invention not only has a short production period, but also the prepared freshwater macro-filamentous green algae module will not deposit into agglomerates in actual use, can achieve the best purification effect, and has low purification cost.

Description

technical field [0001] The invention relates to a preparation process of freshwater large-scale filamentous green algae modules used for purifying eutrophic water bodies. Background technique [0002] With the rapid development of the national economy, the eutrophication of urban and rural water bodies (rivers, ponds, lakes) is also becoming more and more serious under the current situation that the sewage interception pipe network is not perfect, but the relevant indicators of this water body are relatively polluted. Low, large water body; if this kind of water body, it is obviously inappropriate and expensive to use the treatment method of sewage treatment plant (heavily polluted water body) for standard upgrading and purification. [0003] Microalgae are widely used in the treatment of eutrophic water bodies. The symbiosis of bacteria and algae is used to remove nitrogen and phosphorus from the water body. However, the algae are unicellular algae (micro planktonic algae: ...

AI Technical Summary

Problems solved by technology

However, in recent years, the technology of purifying eutrophic water bodies by large filamentous algae has not been popularized and applied. The reason is that it is difficult to obtain the amount of large filamentous green algae that can meet the treatment requirements in a short period of time during environmental protection projects; in addition, It is just a simple method of using cages to carry large filamentous green algae. In practical applications, it is easy to deposit into agglomerates, and the best purification effect cannot be achieved.
