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.
