The present disclosure belongs to the technical field of sewage treatment, and discloses a method and system for enhanced culture of aerobic granular sludge. The system includes a reaction tank, a water inlet and outlet unit, an aeration unit, and a sludge discharge unit. The water inlet and outlet unit includes a water inlet pump, a water inlet electric valve, a liquid flowmeter, a sewage uniform distribution treatment device, buffers, a water drainage pipe, and a water drainage electric valve. The aeration unit includes a blower, microporous aerators, and a gas flowmeter. The sludge discharge unit includes sludge discharge pumps, a sludge discharge pipe, a sludge discharge electric valve, and a sludge concentration meter. In the present disclosure, a multi-point uniform water distribution method is used. When the flow rate of influent water is adjusted, sewage slowly and uniformly flows through a sludge layer from the bottom of the system, so that the concentration of organic matter in raw water is prevented from being rapidly reduced by rapid single-point water intake, the utilization rate of the organic matter in the sewage is increased to the maximum extent, and the efficiency of the system is improved.

A memory management method includes: determining that available storage space of a first memory in a network device is less than a first threshold, where the first threshold is greater than 0 and the first memory stores a first packet queue; and deleting at least one packet at the tail of the first packet queue from the first memory based on the available storage space of the first memory being less than the first threshold. When the available storage space of the first memory is less than the first threshold, a packet queue, namely, the first packet queue, is selected and a packet at the tail of the packet queue is deleted from the first memory.

A method and an apparatus for accessing a website. A specific implementation of the method includes: receiving an access request for the website, the access request comprising a source network address of the access request and a network address of the website; detecting whether the source network address and the network address of the website belong to a same Internet service provider; determining a target inter-network node from a preset inter-network node set in response to detecting the source network address and the network address of the website not belonging to the same Internet service provider, the target inter-network node being an inter-network node connecting a network of an Internet service provider to which the source network address belongs and a network of an Internet service provider to which the network address of the website belongs; and transmitting the access request to the target inter-network node. This implementation improves the speed for accessing a website.

Method and device for accessing website

The present disclosure discloses a method and an apparatus for detecting an access path. A specific implementation of the method includes: in response to receiving an access request for a source website, selecting a plurality of preset paths as candidate paths according to an address of the source website; transmitting the access request to the source website along each of the candidate paths in sequence until a successful transmission is detected; and in response to detecting the successful transmission, recording a successfully transmitting path as a default path for accessing the source website next time. This implementation implements dynamic adjustment of a website access path and maximizes a website access success ratio.
