Bacillus natto activation solution and preparation method and application thereof

Abstract

The invention discloses a Bacillus natto activation solution and a preparation method and application of the activation solution. The method for preparing the Bacillus natto activation solution comprises the following steps: adding 0.5-1.2 parts of Bacillus natto dry powder into 1,000 parts of purified water by mass (the same below), adding 0.005-0.01 parts of avian egg white and 0.015-0.025 parts of bee honey, and aerating for 3-4 hours at a gas-water ratio of 1:1. According to the invention, the Bacillus natto activation solution obtained has high activity, wide thermal adaptability, aerobic-anaerobic facultative ability and high survival rate. The preparation method has a simple technical process, a short startup time of a wastewater treatment system and simple and convenient operation. In the invention, equipment and facilities are arranged compactly, which reduce the occupied floor area and the construction cost. The amount of aeration is decreased by 40%, wastewater is raised for the whole process at one time, and equipment has low power consumption and is energy-effective. The invention improves the treatment function and the effluent water quality, which makes the content of pollutants in the effluent water lower than standard of GB18918-2002.

Description

technical field [0001] The invention belongs to the field of biochemical treatment of sewage, and in particular relates to a bacillus natto activation liquid, a preparation method and an application. Background technique [0002] At present, the treatment capacity of urban sewage in my country is only about 10% of the total discharge, and the treatment rate of urban sewage is only 30%. more grim. The main reason is that the sewage treatment facilities have large investment, high operating costs and large floor area. At present, the commonly used methods include oxidation ditch method, biofilm method, AB method, contact oxidation method and other methods. The above methods all use bacteria and microorganisms to purify sewage. [0003] The above methods have several things in common: [0004] The microbial population in activated sludge is mainly composed of various bacterial populations and microorganisms (protozoa). Fungi and metazoans dominated by rotifers also survived....
