Plant yeast additive and preparation method thereof

Abstract

The invention discloses a plant yeast additive and a preparation method thereof and relates to the technical field of feed additives. The components of the plant yeast additive comprise the following raw materials in percentage by weight: 2-2.5% of dry carambola leaves, 3-3.5% of dry sugarcane leaves, 3-3.5% of dry granadilla leaves, 2-2.5% of dry wild chrysanthemum flowers, 2-2.5% of brown sugar, 0.1-0.15% of dry yeast and the balance of water. The preparation method comprises the following steps: placing the dry carambola leaves, the dry sugarcane leaves, the dry granadilla leaves and the dry wild chrysanthemum flowers into boiling water and soaking for 2-3 hours; then, filtering residues and impurities of the carambola leaves, the sugarcane leaves, the granadilla leaves and the chrysanthemum flowers; and after standing the filtrate, adding the dry yeast and the brown sugar and fermenting for at least 30 days to form sourness to obtain the plant yeast additive. According to the preparation method disclosed by the invention, a fermentation solution obtained after the soak solutions of the four plants are fermented is used as the plant yeast additive, so that not only can the treating effect be improved, but also the sludge domestication time can also be shortened.

Description

technical field [0001] The invention relates to the technical field of additives for treating waste water, in particular to a plant yeast additive and a preparation method thereof. Background technique [0002] After years of construction, my country's water pollution prevention and control work has achieved remarkable results, but the water pollution situation is still very severe. In 2005, the total discharge of wastewater in the country was 52.45 billion tons, and the urban sewage treatment rate was only 1.498 million tons, of which industrial wastewater Accounted for 39% ~ 35%, urban sewage accounted for 61% ~ 65%, urban sewage has become the main source of pollution. [0003] According to the China Environmental Quality Announcement issued by the National Environmental Protection Agency, among the seven major water systems in the country, the water quality of the Pearl River and the Yangtze River is good, the water quality of the Liaohe River, Huaihe River, Yellow Rive...

Problems solved by technology

In 2005, among the 28 nationally controlled key lakes and reservoirs, only 2 met Grade II water quality, only 6 met Grade III water quality; 72% of lakes and reservoirs are no longer suitable for drinking water sources, and 43% of lakes and reservoirs have lost their function

[0008] The traditional activated sludge method and biofilm method mostly use natural or domesticated microbial flora, which can no longer adapt to more and more types of industrial wastewater today.

The use of acclimatized cultures that cannot be effectively maintained continuously, often due to insufficient useful bacteria or poor bacterial activity, leads to low treatment efficiency and consumes a lot of energy
