Abstract: A floating apparatus (3) and an ultrasonic device. A first moving member (33) and a second moving member (34) are configured to reciprocate in an arc-shaped or circular trajectory on a support member (31). Meanwhile, both ends of lift arms (35, 36) are hingedly connected to moving members (33, 34) and a connection base (39), respectively. When a user applies force to the connection base (39) or the lift arms (35, 36), the positions of the first moving member (33) and the second moving member (34) on the support member (31) can be changed, so that the first moving member (33) and the second moving member (34) are distant from and get close to each other on the support member (31) according to the stress in the arc-shaped or circular trajectory. Meanwhile, the angle between the lift arms (35, 36) and the connection base (39), and the moving members (33, 34) can also be changed according to the stress, so that multi-position movement and rotation is achieved for the connection base (39) in a plane. Meanwhile, the lift arms (35, 36) have the lift function, so that the spatial floating in horizontal and vertical directions can be achieved by combining other components. The structure is more simplified while achieving multi-azimuth floating in horizontal and vertical directions, and improves the compactness of the apparatus, and the linkage flexibility is better.

Abstract: Disclosed is a method for the bacterial in situ repairing of soil contaminated with arsenic, wherein the method involves selecting Pseudomonas putida strain MnB1, ATCC 23483 and adding same into soil contaminated with arsenic. Under the effect of the bacteria, the strain uses divalent iron and manganese from the soil as electron donors to introduce same so as to form an active iron manganese composite oxide and also conduct the in situ repair of arsenic in acidified soil. Under the effect of bacteria, exchangeable-form arsenic in soil can be converted into residual-form arsenic, thereby reducing the migration and bio-availability of the arsenic in soil and conducting the in situ immobilization of the arsenic in soil. The process involves simple operations, has low processing costs and wide applicability, and does not involve secondary pollution.
