Problems solved by technology

The purification ball is composed of Bokashi, probiotics and clay. The probiotics are composed of 30% lactic acid bacteria, 30% yeast, 10% photosynthetic bacteria and 30% other bacteria. Bokashi is rice bran, wheat bran, corn flour, The cake is compounded in proportion. In the process of making purification balls, Bokashi and clay are mixed at a ratio of 1:9, and the prepared probiotics and mud are made into mud pellets, which are made after natural drying. The production process is only a simple compounding of several raw materials. The use of clay as the carrier of the bacterial agent is put into the water body and washed by the water flow is not conducive to the colonization of the bacterial agent, and the purification effect is not long-lasting.

Abstract

The invention belongs to the technical field of water purification, and particularly relates to a chelated nano-iron water area purification ball and a preparation method thereof. The purification ball is composed of a probiotic propagation liquid, a solid probiotic agent and river mud; wherein the probiotic propagation liquid is obtained by sewage domestication of probiotics, the solid probioticagent is prepared by co-fermentation of rice bran, wheat bran, soybean meal, nano iron powder, the probiotic propagation liquid, molasses and water, and the probiotics comprise lactobacillus plantarum, saccharomyces cerevisiae, rhodopseudomonas palustris, bacillus subtilis and alcaligenes faecalis. The purification ball disclosed by the invention is large in effective viable count, quick in sewagepurification, thorough in purification, not easy to repeat, free of secondary pollution and low in operation cost.

Description

technical field [0001] The invention belongs to the technical field of water quality purification, and in particular relates to a chelated nano-iron water area purification ball and a preparation method thereof. Background technique [0002] Water is the source of life. With the rapid development of social economy, the pollution of surface water is becoming more and more serious. The main source of sewage is domestic sewage and agricultural sewage containing a large amount of pesticide chemicals. As time goes by, the reservoir water is naturally polluted, and the water quality gradually deteriorates. Eutrophication leads to a sharp increase in algae reproduction, and the death and corruption of algae cells further deteriorates the water quality. , until the odor is serious, and harmful bacteria in the water body multiply in large numbers. At present, the water source purification measures used in my country's drinking water are mainly purified by conventional treatment pro...
