The present disclosure provides a method and an apparatus for processing a vehicle collision, a vehicle, a device and a storage medium. The method includes: obtaining vehicle state information of a target vehicle; the vehicle state information includes: acceleration information of the target vehicle and/or pressure information of a peripheral part in the target vehicle; determining whether a collision occurs to the target vehicle; sending, when it is determined that the collision occurs to the target vehicle, an ejection instruction is sent to an ejection execution mechanism in the target vehicle, the ejection instruction is used to instruct to eject a baffle located at a target position to contact the ground. The baffle is ejected immediately when the present disclosure detects that a collision occurs to the vehicle, which can avoid a secondary collision of the vehicle, thereby improving the safety performance of the vehicle.

The present invention discloses a CoFeO-WTRs composite magnetic catalyst for efficiently degrading atrazine by activating peroxymonosulfate, preparation method and application thereof. The CoFeO-WTRs composite magnetic catalyst is prepared by three steps: the first step is acid-leaching of WTRs, using the WTRs as iron source to provide the iron ions required for the synthesis of CoFeO; the second step is preparing of a precursor, synthesizing CoFeOby chemical co-precipitation method and uniformly loading the prepared CoFeOon the WTRs; and the third step is calcining the precursor to synthesize the CoFeO-WTRs composite magnetic catalyst. The catalytic performance of the CoFeO-WTRs composite magnetic catalyst prepared by the present invention is evaluated using PMS as an oxidant and atrazine as a target pollutant. The CoFeO-WTRs can efficiently remove atrazine from the actual water, exhibiting good potential for practical application.

The present invention provides a biomimetic polymer for stabilizing wellbore, a method for preparation of the biomimetic polymer, and a drilling fluid. The polymer contains carboxymethyl chitosan that serves as a backbone and dopamine-derived groups grafted on the backbone. The polymer provided in the present invention can improve the strength of shale in the wellbore, seal the shale pores and reduce the filter loss of drilling fluid, and thereby attains an effect of stabilizing the wellbore in shale formation in drilling process.
