Method of synthesizing artificial soil on basis of algal mud

Abstract

The invention relates to a method of synthesizing artificial soil on the basis of algal mud. The artificial soil is prepared from the following ingredients including the algal mud, fly ash, straws, pH regulators, buffer agents, chelates and microbial preparations, wherein the mass percentage of the algal mud is 5 to 10 percent; the mass percentage of the fly ash is 80 to 90 percent; the mass percentage of the straws is 5 to 10 percent; 0.01 to 1000g of pH regulators, 0.01 to 1000g of buffer agents, 0.01 to 500g of chelates and 0.05 to 500g of microbial preparations are added in one ton of the mixture of the algal mud, the fly ash and the straws. The method overcomes the defects of low blue-green algae dewatering concentration efficiency, complicated detoxification process, low resource utilization rate and the like. The fly ash and the blue-green algae are mixed and ground, so that the moisture of the blue-green algae can fast enter the fly ash; then, open air aging and stabilization are performed. A great number of organic matter in the blue-green algae take a humification effect; the formation of artificial soil aggregate structure is promoted; partial organic matter takes a mineralization effect; various nutrients can be decomposed and released; the method of using the algal mud to produce the artificial soil has better economical performance and high operability.

Description

technical field [0001] The invention relates to a technology for synthesizing artificial soil with algae mud as the main raw material, which belongs to the field of environmental management, and in particular to a method for synthesizing artificial soil based on algae mud. Background technique [0002] In recent years, lake eutrophication has become a global water pollution problem. According to a survey by the United Nations Environment Program (UNCD), 30%-40% of lakes and reservoirs worldwide suffer from eutrophication to varying degrees. Impact. Among the 131 major lakes in my country, 67 lakes have reached the level of eutrophication, accounting for 51.2%. Among the 39 representative reservoirs, 12 reached the eutrophication level, accounting for 30%. Among the five major freshwater lakes, Taihu Lake, Hongze Lake and Chaohu Lake have reached the level of eutrophication, while Poyang Lake and Dongting Lake are also in transition to eutrophication. The most effective wa...

Problems solved by technology

In many cyanobacteria resource utilization measures, due to the problem of high processing costs in protein extraction, additives, growth promoters and other treatment methods, it is impossible to realize the timely treatment of a large number of cyanobacteria

[0004] Before the present invention was made, cyanobacteria were currently utilized mainly as biomass energy materials, raw materials for biological fertilizers, raw materials for microbial cultivation, and extraction of biologically active substances, etc., but there were low dehydration and concentration efficiency of cyanobacteria, complex detoxification process, and the need for fixed workshops and storage of cyanobacteria. Problems such as pools and special equipment, and low resource utilization

In particular, the outbreak of cyanobacteria is concentrated. Only by meeting the short-term, high-intensity treatment, disposal and resource utilization methods can better avoid the cyanobacteria during the outbreak period. After the salvage, it is too late to treat and dispose and need to be piled up and stored, which not only occupies land, but also rots and stinks. and re-entering the water body to cause secondary pollution
