Embodiment 1

[0045] A microbial agent for purifying river sewage, comprising the following components in parts by weight: 30 parts of Bacillus natto, 20 parts of nitrifying bacteria, 10 parts of white rot fungi, 10 parts of pseudomonas, and 30 parts of photosynthetic bacteria share.

[0046] Its preparation method comprises the following steps:

[0047] (1) Inoculate Bacillus natto, nitrifying bacteria, white rot fungi, pseudomonas, and photosynthetic bacteria into solid medium for activation;

[0048] Among them, the mass percentage of each component of the solid medium is: beef extract 0.3%, peptone 0.5%, sodium chloride 1%, agar 5%, adjust the pH to 7.0; inoculate each strain on the solid slant medium Activation culture at 30°C for 20 hours;

[0049] (2) Bacillus natto, nitrifying bacteria, white rot fungi, pseudomonas, and photosynthetic bacteria after step (1) were respectively inoculated in the seed medium for strain culture, so that the number of each strain reached 1 ~8×10 8 ; ...

Abstract

The invention relates to a microbial agent for purifying river wastewater and a preparation method of the microbial agent. The microbial agent comprises the following components in parts by weight: 20-40 parts of bacillus natto, 10-30 parts of nitrobacteria, 5-15 parts of white-rot fungi, 5-15 parts of pseudomonas and 10-40 parts of photosynthetic bacteria. The microbial agent is well-adapted and has the capabilities of fast forming dominant bacterial communities and replenishing indigenous rhizobia to the water body; and the microbial agent can be used for reducing the COD (Chemical Oxygen Demand), NH3-H, total nitrogen, TP (Total Phosphorus) and the like, removing odor and color and producing high-activity bio-enzyme to suppress the growth of harmful bacteria and acceleratively decompose residual baits as well as animal and plant residues, and a remarkable water quality purifying effect is achieved.

Description

technical field [0001] The invention relates to a microbial bacterial agent, in particular to a microbial bacterial agent for purifying river sewage and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy, my country's water environment problems have become increasingly prominent, and urban and rural water environments have encountered unprecedented threats. Existing surveys have shown that more than 90% of the rural water ecology in the Yangtze River Delta region has lost its basic functions, urban and rural rivers have been severely degraded due to pollution and ecosystems, and the water quality of the rivers has basically been at V or worse. Nutritization, the most important pollution indicators are permanganate index and ammonia nitrogen. In addition, most of the river water turns black and smelly, and the pathogenic bacteria exceed the standard, resulting in a severe environmental and ecological situation, whic...
