An advanced nitrogen removal method using partial nitrification-denitrification coupled two-stage autotrophic denitrification. Sewage is introduced into a first pool for partial nitrification-denitrification treatment, and then introduced into a first regulating reservoir. Dissolved oxygen content in the first pool is kept at 0.4-0.6 mg/L. Water is discharged when a molar ratio of nitrite nitrogen to ammonia nitrogen in the first regulating reservoir is 1.0-1.3:1. Effluent in the regulating reservoir is introduced into a second pool for anaerobic ammonia oxidation treatment, and then introduced into a second regulating reservoir. In the second pool, pH is 7.0-7.4, a temperature is 22-28&#xb0; C. Effluent in the second regulating reservoir and sulfides are introduced into a third pool for denitrification treatment. Water is discharged. In the third pool, pH is 7.5-8.0, a temperature is 28-32&#xb0; C., a mass ratio of sulfur to nitrogen is 1.9-2.0:1.

An HDMI cable, an HDMI connector and an HDMI interface for a high-definition video/audio apparatus are provided. The HDMI interface includes the HDMI connector and the HDMI cable. The HDMI connector includes a connecting terminal having an extending cable terminal arranged in parallel in a main body. The HDMI cable includes at least one connecting unit consisting of a plurality of parallel metal wires. An insulating unit covers an outside of a face of the connecting unit, in such a manner that the metal wires are parallel and isolated from each other. The present invention is using design of single row of the connector terminal and single row of the HDMI cable, to simplify an HDMI interface structure and reduce size and weight, and manual identification is not required for pin bit definitions, which simplifies production process, reduces the manual work, and greatly improves production efficiency.
