Abstract

The invention belongs to the technical field of environmental protection and discloses a microbial preparation for purifying breeding wastewater. A preparation method of the microbial preparation comprises the following steps: uniformly mixing mixed bacteria liquid, sawdust and diatomite according to a weight ratio of 1 to 1 to 1, drying at the low temperature of 4 DEG C, and controlling the water content to be 8%-10% after drying. The invention further discloses a use method of the microbial preparation. According to the microbial preparation, strains are reasonably mixed, are symbiotic and coordinative, and are not mutually antagonistic; the preparation method is simple and feasible, the operation is simple and convenient, and the industrialized production is facilitated.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a microbial preparation for purification and treatment of aquaculture wastewater and its application. Background technique [0002] With the development of the breeding industry and the increasingly fierce competition in the industry, the large-scale and intensive development of animal husbandry has become an inevitable trend. Large-scale pig farms have higher livestock and poultry breeding technology, unified management, and reduced costs. The economic benefits are improved, but the discharged wastewater has a poor impact on the environment. Pig farm wastewater is mainly composed of urine, residual feces, feed residue and flushing water, among which flushing water accounts for the vast majority. The water quality characteristics of pig farm wastewater are related to the structure of the pig house, the way of cleaning manure and the use of flushing w...
