Embodiment 1

[0026] A natural circulation microbial agent for water purification, quality standard:

[0027]

[0028] According to experiments, the bacterial strains involved in the present invention are all known bacterial strains, and the bacterial agents using the bacterial beads all have the same water purification effect.

[0029] The preparation method of the natural circulation microbial bacterial agent for purifying water quality, the steps are as follows:

[0030] (1) Production of medium

[0031] The production method of this culture medium is as follows, every 1L of water is added 0.5g potassium dihydrogen phosphate (KH 2 PO 4 ), 0.2g magnesium sulfate heptahydrate (MgSO 4 7H 2 O), 0.4g sodium chloride (NaCI), 1.2g ammonium chloride (NH 4 CI), 0.05g calcium chloride dihydrate (CaCI 2 2H 2 O), 0.3g yeast extract (yeast extract), 1ml mineral solution (each 1L contains 25% (v / v) hydrogen chloride (HCI) 1ml, zinc chloride (ZnCI 2 ) 70mg, manganese chloride tetrahydrate (M...

[0034] Experimental Example 1: Experimental Results of Water Quality Purification of Wastewater

[0035] Take 20L each of garbage treatment plant sewage, human feces waste water, pig raising waste water and leather waste water and put them into a cylindrical water tank respectively, and put them into 0.2, 10, 10 and 4 ml of the natural circulation microbial agent prepared in Example 1 respectively and stir them, respectively. After 4 hours, 1 day, 1 day, and 8 hours, add natural circulation microbial agents. In order to test the effect of water purification treatment, test BOD, COD, SS, T-N, T-P at different times.

Abstract

The invention discloses a natural cycle microbial agent for purifying water and a preparation method thereof. The natural cycle microbial agent is prepared from eight bacteria of allochromatium (allochromatium), lamprocystis (lamprocystis), halorhodospira (halorhodospira), chromatium (chromatium), nitrosomonas (nitrosomonas), nitrobacter (nitrobacter), nitrosomonas (nitrosomonas) and pseudomonas (pseudomonas). The effective viable counts of the eight bacteria in a fermentation liquor respectively are greater than or equal to 1.0*10<8>CFU / ml. The microbial agent disclosed by the invention has good cleanup effects on kinds of sewages and wastewaters.

Description

[0001] technical field [0002] The invention belongs to the technical field of environmental protection and relates to a microbial bacterial agent, in particular to a natural circulation microbial bacterial agent for purifying water quality and a preparation method thereof. [0003] Background technique [0004] In recent decades, with the rapid development of science and technology and social economy, serious environmental pollution and ecological damage have been brought about. The great potential of microorganisms to degrade pollutants plays an important role in controlling pollution and remediating the environment. Sewage (wastewater), waste gas and solid waste produced by human production and living activities can be treated by biological methods. In the current technology, there is still a lack of a microbial bacterial agent that has a good water quality purification effect on various production and domestic wastewater. [0005] Contents of the invention [0006...
