Preparation process of fresh water filamentous green alga module for eutrophic water purification

Abstract

The invention discloses a preparation process of a fresh water filamentous green alga module for eutrophic water purification, the filamentous green alga module is composed of a plurality of filamentous green alga module units, and the preparation process comprises the following steps: step 1, taking river water to prepare standby water; step 2, selecting cladophora, purifying the cladophora, and placing the cladophora in a refrigerator at 4 DEG C for dark preservation for 1-2 days; step 3, putting the filamentous green alga module units into a seedling collecting pool; step 4, taking out the seed algae, cutting into algae sections, and pouring into the seedling collecting pool; step 5, after cladophora spores or gametes reach the preset attachment number, moving the large filamentous green alga module units to a nursery pond to be cultured; and step 6, connecting the large filamentous green alga module units after seedling culture in series to form the large filamentous green alga module. According to the preparation process, the production period is short, the prepared fresh water filamentous green alga module cannot be deposited and clustered in actual use, the optimal purification effect can be achieved, and the purification cost is low.

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.
