Abstract: Provided are an air conditioner and a control method thereof. The control method includes following steps: controlling a compressor of an air conditioner to be in an operating state or a shutdown state according to a superheat degree of injected vapor of the compressor and a continuous duration of the superheat degree; controlling the compressor to be in a shutdown state for maintenance according to a number of shutdown times of the compressor, so as to maintain a gas supply pipeline of the compressor. By adopting such a configuration, an operating condition of the compressor can be accurately and effectively determined, which enables the compressor to be maintained timely, thereby preventing the compressor from being damaged as a result of operating in a severe condition, and enhancing operation reliability of the compressor and the air conditioner.

Abstract: The present invention relates to a process for biochemical treatment of waste water. The process uses a nano material such as carbon black to induce micro to degrade organic pollutants in the waste water which are generally unable or hard to be degraded and thereby greatly enhance the effect of biological cleaning of waste water. The effect is more prominent for the waste water that is hard to treat by the conventional biochemical treatment, high concentration waste water, and highly poisonous waste water. The process of the present invention is widely usable in the aerobic, oxygen-facultative or anaerobic biochemical treatment systems.
