A double-chuck mechanical pencil comprises a barrel, a barrel cap detachably attached to a front end of the barrel, a lead tank inserted in the barrel, a feed chuck for feeding leads, combined with the lead tank, a sleeve bolster disposed on the front side of the feed chuck, and a holding chuck combined with the sleeve bolster. A holding chuck unit including the holding chuck and the sleeve bolster, and a feed chuck unit including the feed chuck and a sleeve can come into contact with each other in the barrel cap.

The invention relates to the field of wastewater treatment, and relates to a biological degradation method of nitrogen-containing heterocyclic compound wastewater. An oxidation state compound is added in the nitrogen containing heterocyclic compound wastewater, an anaerobic environment is formed by micro aeration, and mixed electron acceptors of dissolved oxygen and the oxidation state compound simultaneously exist in the system; an upflow biological aerated filter is used as a main reaction device, an optimal degradation effect of nitrogen-containing heterocyclic compounds is achieved according to different components and concentrations of the nitrogen-containing heterocyclic compounds, the pH is controlled to 7.0-7.5, the concentration of the dissolved oxygen is controlled to 0.05-0.3 mg / L (water discharged from the upper part of the filter), and the range of the oxidation-reduction potential is controlled to 150-50 mv; under an anaerobic aeration condition, with the nitrogen-containing heterocyclic compounds as electron donors and oxygen and oxygen-containing compounds as electron acceptors, under the combined effects of micro aerobic bacteria, facultative anaerobic bacteria, aerobic / anoxic denitrifying bacteria and the like, the nitrogen-containing heterocyclic compounds are completely degraded into carbon dioxide and water.

The invention discloses a strain of enterobacteriaceae and its application. The strain is Enterobacteriaceae ( Enterobacter sp.) FL, was deposited in the General Microorganism Center (CGMCC) of China Committee for the Collection of Microorganisms on January 12, 2016, with the deposit number CGMCC No.11993. The Enterobacter FL can be applied in the field of nitrogen-containing organic wastewater treatment, and removes nitrate nitrogen in the wastewater through denitrification under aerobic conditions; the Enterobacter FL secretes protein, polysaccharide, etc. as the main components during the denitrification process Extracellular polymers, which can trigger the spontaneous aggregation and sedimentation of bacterial cells, and realize the separation of bacteria and water. The strain has the ability of aerobic denitrification and denitrification, and can self-aggregate to form precipitates at the same time. It has the characteristics of self-sinking, so that the reactor with this strain as a functional bacterium can be constructed later to realize aerobic denitrification and mud-water separation. It is possible to obtain clarified effluent, which has broad application prospects and good social and environmental protection benefits.
