Problems solved by technology

[0003] However, the content of phosphorus-accumulating bacteria in ordinary sewage treatment equipment is too low and the effect of phosphorus-accumulating bacteria is very poor. They cannot effectively reproduce into dominant bacteria and efficiently absorb phosphorus in the sewage solution, and the phosphorus in the effluent seriously exceeds the standard.

Embodiment 1

[0025] 1. Screening of phosphorus accumulating bacteria

[0026] 1.1 Sampling: Take 5g of river silt from Donghu Campus of Zhejiang A&F University.

[0027] 1.2 Enrichment culture: add the sample to 100ml LB liquid medium, shake at 37°C and 200rpm for 60min. Take 10ml of the shaken sample and add 100ml of enrichment medium, first insert the enrichment medium with the lowest concentration of potassium dihydrogen phosphate, culture on a shaker at 37°C and 200rpm for 3 days, and then transfer to the concentration of potassium dihydrogen phosphate The higher enrichment medium was continued to be cultivated according to the above conditions, and the enrichment was carried out in turn until the enrichment medium of 4 concentrations were all cultured.

[0028] 1.3 Purification: After the enrichment is completed, the enriched bacterial liquid is gradiently diluted to an appropriate concentration and spread on an LB plate, and cultured at 37°C for 12-24 hours.

Abstract

The invention provides a strain of Acinetobacter CL04Acinetobacter sp.CL04 and the application of the strain. The bacterial strain of the present invention efficiently accumulates phosphorus and makes it a dominant bacterium in sewage treatment equipment, absorbs a large amount of phosphorus in sewage, forms polyphosphate in the body, and achieves the purpose of phosphorus removal by discharging bacterial sludge and depositing. This strain can be well integrated into the currently commonly used biological sewage treatment process, and is suitable for domestic sewage in villages, towns and cities, as well as sewage and wastewater in rivers, commerce and industry, etc. Low, phosphorus removal in sewage treatment equipment (such as sewage purification tanks in villages and towns, urban sewage treatment plants, etc.) will have a wide range of application values.

Description

technical field [0001] The invention relates to a new strain of bacteria—acinetobacter CL04Acinetobacter sp.CL04, and the application of the strain to remove phosphorus in sewage. Background technique [0002] The intensification of human activity has brought enormous pressure to the ecological environment, especially a large amount of industrial, agricultural and domestic sewage not only brought great pressure to sewage treatment, but also caused phosphorus to flow into various water bodies, resulting in eutrophication of water bodies. At present, the treatment of phosphorus in sewage treatment mainly includes chemical flocculation and sedimentation method and microbial phosphorus removal. Microbial phosphorus removal is safe, non-toxic, low-cost, economical and practical. The chemical method is mainly to add aluminum salts, iron salts and phosphorus to produce insoluble precipitates, while the microbial method is mainly to facilitate the absorption of phosphorus in sewage ...
