The preparation method comprises the following steps:

Examples of the invention

1. The culture sewage contains a large amount of organic substances, lipids, fibers and inorganic salt components which are all substances required by the growth of microorganisms, the composite microorganisms and the enzymes produced by the microorganisms can decompose the substances into micromolecular substances, carbon dioxide and water, and the micromolecular substances are further decomposed by a large amount of microorganisms. Improving the odor treatment efficiency and reducing COD, BOD and TSS.

2. The composite microorganism is used for treating sewage discharged by a paper mill, and the data before and after treatment are as follows:

water sample	CODcr（mg/L）	NH3-N（mg/L）	Chroma (multiple)	Turbidity (NTU)	PH
						Before treatment	15000	300	8000	3600	8.0
After treatment	305.6	56	100	102	7.0

The composite microorganism has obvious effect of treating harmful substances in water and good effects of deodorizing, removing phosphorus and reducing NH 3-N.

3. Composite microorganism for sewage treatment of sewage plant

The sludge after the biochemical treatment of the municipal domestic sewage is black, has high water content of over 99 percent and has slight odor. By adding a small amount of compound microorganisms into the sludge, stirring at a low speed, coagulating and settling, and comparing with PAM (equal dosage), the sludge settling ratio (SV 30) of two groups of sludge samples is detected, and the test data is as follows:

water sample	SV30（%）
		Natural sedimentation	86.92
Concentration of bioflocculants	52.94
		PAM concentration	65.39

The data show that under the same dosage, the compression sedimentation ratio of the composite microorganism to the sludge can reach 52 percent, and the PAM is only 65 percent, so that the concentration performance of the composite microorganism to the sludge is stronger than that of the PAM, and in addition, after cation concentration, the sludge supernatant is clear and has no impurities, thereby being beneficial to the reflux of the supernatant.

4. Treatment of polluted water source in acid coal yard

In the coal mining process, a large amount of metals such as iron and manganese enter underground water or flow into drinking water of residents along with spring, so that the metal ions of the drinking water exceed the standard. Collecting the severely polluted water sample, wherein the appearance is light yellow,

、Fe²⁺and Mn²⁺The content is seriously out of limits. The treatment scheme of aeration oxidation and (PAC + PAM) flocculation is adopted by customers, and the effect is poor. Aiming at the characteristics of the water sample, the original process is not changed, only the flocculating agent (PAC + PAM) is changed into a biological flocculating agent, and after the flocculating agent is treated, the water sample is treated

、F e²⁺And Mn²⁺The content is obviously reduced, and the requirement of the metal ion content of the drinking water source specified by the state is met.

Data of the supernatant after treatment:

water sample	Iron content (mg/L)	Manganese content (mg/L)	Settling time (min)
