Abstract

The invention belongs to the technical field of agricultural wastewater treatment, discloses an agricultural microbial agent and a preparation method thereof, and particularly discloses a culture medium, the culture medium comprises the following components: tea residue leachate, a carbon source, a nitrogen source and trace elements, and the preparation method of the tea residue leachate comprises the steps of tea residue filter pressing, leachate collection and filtration to obtain the tea residue leachate. The invention provides a culture medium prepared from tea residue leachate. The culture medium can be effectively used for culturing bacillus thuringiensis. The tea residue leachate is prepared into the culture medium, so that the treatment problem of the high-concentration tea residue wastewater can be effectively solved, the loss of useful substances in the tea residue wastewater is prevented, the utilization rate of the tea residue wastewater is improved, and meanwhile, the pollution of the tea residue wastewater to the environment is also reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural wastewater treatment, and in particular relates to an agricultural microbial inoculum and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy and the improvement of people's living standards, tea drinks are becoming more and more common in our lives. Tea residue leachate refers to a kind of high-concentration organic wastewater produced under the action of physical and biological degradation of tea residues such as compaction and fermentation, as well as the seepage of precipitation and groundwater during the manufacturing process of tea beverages. my country's tea beverage manufacturing industry discharges more than 10 million tons of high-concentration tea residue leachate every year, which is the main source of pollution for tea beverage manufacturing enterprises and the most difficult to deal with. The problem of wastewater treatm...
