The invention discloses a payment authentication method, a device thereof and a system thereof, belonging to the computer technical field. The method comprises the following steps of receiving a payment authentication request sent by a terminal, detecting whether the identification information in the payment authentication request is same with the prestored identification information, extracting a current voice characteristic if the identification information in the payment authentication request is same with the prestored identification information, matching the current voice characteristic with a prestored voiceprint model, and sending authentication reply information for allowing a payment operation to the terminal if the current voice characteristic is successfully matched with the prestored voiceprint model. According to the payment authentication method, the device thereof and the system thereof, a current voice signal is confirmed through the voiceprint model, after the confirmation is successful, the subsequent payment operation is allowed, a problem that a server needs to send an authentication message and the operation cost is increased in the payment operation process in the prior art is solved, an effect that the payment security can be greatly raised by only using the voiceprint identification of the voice signal is achieved, and the operation cost brought by message authentication is greatly reduced.

The invention discloses a method for treating coking wastewater, and relates to the technical field of coking wastewater treatment. A coking wastewater treatment system is adopted for treating, the wastewater treated by the coking biochemical system is pumped into a water distributor, the wastewater is injected into the bottom of an inclined-tube sedimentation tank by the water distributor, the wastewater is blocked by an inclined-tube packing zone in the rising process, the wastewater is discharged from the top of the inclined-tube sedimentation tank after part of suspended matters are removed to enter an upper column liquid tank, the wastewater is pumped to a shallow sand filter group by an upper column liquid pump and filtered and then enters a resin adsorption tower, the wastewater is adsorbed by resin and then the effluent flows into a tail water tank from the tower bottom. By adopting the method, the intercepting efficiency of chroma, COD and total cyanides is high, the yield of concentrated pollutants is low, the water quality stability of discharged tail water is good, the water quality and stability of the tail water are effectively improved, and the water quantity is reduced significantly; and the method has the advantages of short flow, low space occupation, appropriate investment, low operation cost and the like.

The invention discloses a distributed file deletion method, which comprises the following steps: setting a mark to be deleted for each preset directory of a file system, wherein the mark to be deletedcomprises a time to be deleted; setting the preset directory whose deletion time is shorter than the current system time as the directory to be deleted every preset cycle; performing a delete operation on the data of the directory to be deleted. As that mark to be deleted are added to each preset directory, As that current system time is long than the time to be deleted, and the data under the preset directory is deleted, it can be seen that the deletion method is simple and does not require the user to pay attention to the operation, avoids the operation of manual deletion or relying on theupper application deletion when the stored data is over-aged, thereby realizing the automatic deletion of the over-aged preset directory, reducing the operation cost, and improving the customer experience. The present application also provides a distributed file deletion apparatus and system and a computer-readable storage medium, which have the above-mentioned beneficial effects.

The invention discloses a disposable anti-counterfeiting communication terminal; the disposable anti-counterfeiting communication terminal comprises digital equipment which is provided with a lock, can read and display the number of a mobile phone card and can be communicated with a telephone; the digital equipment is arranged at an opening of a product packaging; the specialized mobile phone card is inserted into the digital equipment and is bound with the unique number; the number automatically becomes invalid once being dialed; when the product packaging is needed to be opened, after the mobile phone card is inserted into the digital equipment, the number of the mobile phone card is displayed on the digital equipment immediately; a mobile phone or the telephone is used for dialing the displayed number of the mobile phone card, and after connection, the lock of the digital equipment is automatically opened, thereby the product packaging is opened, and the mobile phone card becomes invalid immediately; and the anti-counterfeiting communication terminal has the advantages of being capable of leading merchants to establish back-stage management systems with no need for spending lots of labor power and material resources, reducing the operational cost of the merchants, being more convenient and faster for consumers to use, greatly reducing counterfeit behaviors of lawbreakers and effectively ensuring lawful rights and interests of the merchants and the consumers.
