Embodiment 1

[0026] The composite microbial agent for repairing lead-containing wastewater is prepared according to the following process:

[0027] Rhodopseudomonas palustris ATCC 17001, Bacillus stearothermophilus ATCC 12976, Arthrobacter crystal-forming ATCC15481, Acinetobacter calcoacetate ATCC 33304, Oxidobacillus xylosus ATCC 15173, Bacillus cereus ATCC 10876 were respectively cultured on slant, Shake flask seed culture and fermenter culture to obtain fermentation broth; the concentrations of the above six fermentation broths were all controlled at 1×10 10 cfu / ml;

[0028] Fermentation liquid of Rhodopseudomonas palustris, fermentation liquid of Bacillus stearothermophilus, fermentation liquid of Arthrobacter crystal forming, fermentation liquid of Acinetobacter calcium acetate, fermentation liquid of Oxidobacillus xylosus and fermentation liquid of Bacillus cereus according to the ratio of 2:2 : Mix evenly at a volume ratio of 3:3:4:4 to obtain a composite bacterial liquid;

Embodiment 2

[0032] The composite microbial agent for repairing lead-containing wastewater is prepared according to the following process:

[0033] Rhodopseudomonas palustris ATCC 17001, Bacillus stearothermophilus ATCC 12976, Arthrobacter crystal-forming ATCC15481, Acinetobacter calcoacetate ATCC 33304, Oxidobacillus xylosus ATCC 15173, Bacillus cereus ATCC 10876 were respectively cultured on slant, Shake flask seed culture and fermenter culture to obtain fermentation broth; the concentrations of the above six fermentation broths were all controlled at 1×10 10 cfu / ml;

[0034] Fermentation liquid of Rhodopseudomonas palustris, fermentation liquid of Bacillus stearothermophilus, fermentation liquid of Arthrobacter crystal forming, fermentation liquid of Acinetobacter calcium acetate, fermentation liquid of oxidobacillus xylosus and fermentation liquid of Bacillus cereus according to 3:3 : Mix evenly at a volume ratio of 5:5:7:7 to obtain a composite bacterial liquid;

[0035] Add polysty...

Embodiment 3

[0038] Lead removal test for lead-containing wastewater:

[0039] Samples: Take lead-contaminated water samples, in which lead concentration is 179mg / L and COD is 634mg / L;

[0040] Treatment process: adjust the pH of lead-containing wastewater to 7, then evenly sprinkle 20 grams of compound bacterial agent per cubic meter of liquid, biological treatment for one week, filter and sterilize the liquid through a plate and frame filter, and finally discharge, use ICP-AES Determination of Pb 2+ content.

[0041] Group: take the example of the composite bacterial agent in Example 1, sample and determine the pollutant data; and set a control group to detect the compatibility effect of each bacterial strain in the bacterial agent;

[0042] Control group 1: without adding Rhodopseudomonas palustris, the rest are the same as in Example 1;

[0043] Control group 2: do not add bacillus stearothermophilus, all the other are the same as embodiment 1;

[0044] Control group 3: no addition o...

Abstract

The invention belongs to the technical field of microbes and discloses a composite fungicide for remediating lead-containing wastewater. The composite fungicide is prepared from a compound bacterium solution and an adsorption carrier and is characterized in that the compound bacterium solution is prepared from marsh rhodop seudanonas palustris, bacillus stearothermophilus, arthrobacter crystallopoietes, acinetobacter calcoaceticus, achromobacter xylosoxidans fermentation liquor and bacillus cereus. The composite fungicide can effectively remediate lead polluted wastewater, and sludge production amount is small.

Description

technical field [0001] The invention belongs to the technical field of microbes, and in particular relates to a composite bacterial agent for repairing lead-containing wastewater. Background technique [0002] In recent years, heavy metal pollution has become increasingly serious, seriously threatening ecological balance, food safety and human health. Among them, lead (Pb), cadmium (Cd), mercury (Hg), arsenic (As), and chromium (Cr) are considered to be the "five poisons" among the main heavy metal pollutants. Lead is a widely distributed element in nature, and it is also one of the elements commonly used in industry. It has a very wide range of uses in industrial and agricultural production. Such as the manufacture of lead batteries, paints and paints, glass and other optical instruments, and radioactive radiation protective clothing. Lead and its compounds are non-degradable environmental pollutants that can flow into the environment in large quantities through waste wat...
