Problems solved by technology

[0004] However, when dealing with water pollution, oily pollutants such as oil are insoluble in water and have a lower density than water, so they all float on the water surface, while the added granulated sludge is generally suspended in the sewage or deposited at the bottom of the water. Only a part of the granulated sludge will float on the water surface to deal with oily pollutants such as petroleum, resulting in low utilization rate of granulated sludge, resulting in a decline in the degreasing effect and efficiency of sewage

Abstract

The invention relates to an oil-removing microbial agent and a sludge processing technology applying the same, and relates to the technical field of activated sludge, the oil-removing microbial agentcomprises the following components by weight: 16-20% of Bacillus, 14-18% of Saccharomyces, 12-16% of Micrococcus, 20-24% of a biological synergistic carrier, and 26-34% of a nutritional agent. The method comprises the following steps: S1, compounding the bacillus, the saccharomycetes, the micrococcus, the nutritional agent and the biological synergistic carrier to obtain granulated sludge; S2, enabling wastewater to sequentially pass through a grid, an adjusting tank, a reaction tank and a secondary sedimentation tank, and adding the granulated sludge prepared in the step S1 into the reactiontank; and S3, allowing the sludge precipitated in the secondary sedimentation tank to flow back to the reaction tank, discharging the wastewater obtained after precipitation after detected to be qualified, and allowing the wastewater obtained after precipitation to flow back to the reaction tank to be continuously treated if the wastewater is not qualified. The biological synergistic carrier is added and used for loading the microbial inoculum to form the granulated sludge, and the utilization rate of the granulated sludge can be increased due to the existence of the biological synergistic carrier, so that the oil removal effect and efficiency of the sewage are improved.

Description

technical field [0001] The invention relates to the technical field of activated sludge, in particular to an oil-removing bacterium agent and a sludge treatment technology using the bacterium agent. Background technique [0002] As one of the important energy sources, petroleum has been widely used all over the world, and the ensuing petroleum hydrocarbon pollution has caused serious harm to the soil and water environment where human beings live. The methods currently used for oil pollution control mainly include physical remediation, chemical remediation and biological remediation. Compared with traditional physical and chemical methods, bioremediation has the advantages of less economic cost, less impact on the environment, fewer remaining problems, minimizing the concentration of pollutants, and shorter repair time. [0003] There is an existing granulated sludge (HJDL) degreasing process, which takes the enhanced biochemical reaction as the core, and through the additio...
