A kind of rice husk-based cyanobacteria treatment agent and preparation method thereof

Abstract

The invention discloses a rice hull based cyanobacteria treating agent, which is prepared from the following raw materials in parts by weight: 40-50 parts of rice hulls, 5-10 parts of attapulgite, 3-5 parts of corn starch, 0.3-0.5 part of disodium edentate, 0.05-0.1 part of a polyaspartic acid, 0.1-0.2 part of an oxalic acid, 0.1-0.2 part of a tannic acid, 0.3-0.5 part of sodium chloride, 1-2 parts of calcium carbonate, and 10-15 parts of a modified additive. The cyanobacteria treating agent disclosed by the invention can effectively adsorb and remove cyanobacteria in water, and is good in sterilizing and algae removal effects, and rapid in algae removal speed; the treating agent has a certain heavy metal removal function; the treating agent is rich in raw material sources, low in cost and good in economy, and has good biodegradability and environmental compatibility; and the treating agent is environment-friendly, pollution-free, and strong in practicability.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a rice husk-based cyanobacteria treatment agent and a preparation method thereof. Background technique [0002] Cyanobacteria bloom is a phenomenon in which cyanobacteria rapidly proliferate in large numbers in water bodies to form cyanobacteria colonies visible to the naked eye or cause changes in the color of water bodies. In recent years, environmental pollution has become increasingly serious, especially the aggravation of eutrophication in water bodies, resulting in frequent outbreaks of cyanobacteria blooms in water bodies, which brings great inconvenience to the lives of local residents and poses a serious threat to economic production and people's health. . [0003] At present, the prevention and control measures for cyanobacteria mainly include physical methods, chemical methods and biological methods. Common physical methods are water injection, bottom mud digging, etc....

AI Technical Summary

Problems solved by technology

Common physical methods are water injection, bottom mud digging, etc., but this method requires a lot of manpower and material resources, and the effect is relatively short-term, and cannot fundamentally solve the problem of cyanobacteria blooms

The use of chemical agents such as copper sulfate can achieve a certain effect of algae removal, but frequent use of chemical agents is likely to damage the ecosystem population structure in the aquaculture water, and is toxic to the environment

Biological methods mainly include microbial control and food chain control, etc., but this method is slow to take effect, and it is not easy to establish a dynamic ecological balance system in the water body
