An anaerobic-AO-SACR combined advanced nitrogen removal system for high ammonia-nitrogen wastewater, in which high ammonia-nitrogen wastewater first enters an anaerobic reactor to remove most of organic matters from the wastewater, effluent water enters an AO reactor for nitrogen removal by pre-denitrification in an anoxic zone and for removal of the remaining organic matters and nitrification of ammonia nitrogen in an aerobic zone, and then the effluent water enters an intermediate pool. Meanwhile, under the control of a water quality testing device and a PLC controller, a part of raw water is introduced into the intermediate pool to adjust the carbon nitrogen ratio of the wastewater. Then, the effluent water enters an SACR reactor, and the wastewater undergoes pre-denitrification-nitrification-endogenous denitrification precisely by using the characteristics of denitrifying bacteria and through adjustment and control of PH/DO/ORP testers and the PLC controller on the SACR reactor so as to realize advanced nitrogen removal.

An automatic sewage regulation system and a regulating method are provided. The automatic sewage regulation system is disposed between preset sewage sources and a preset sewage treatment apparatus and includes an equalization tank and an automatic sewage regulating device. The automatic sewage regulating device includes sensing modules for sensing and transmitting water quality sensing values of sewage in the preset sewage sources to a control module which outputs regulating signals to water flow regulators, so that the water flow regulators can regulate flowing volumes of the sewage of the preset sewage sources according to the regulating signal, to keep a water quality sensing value of the sewage in the equalization tank within a preset range, thereby preventing the equalization tank from converging sewage having excessively-high or excessively-low water quality sensing value. As a result, burden of a preset sewage treatment apparatus can be reduced.

Described are methods for monitoring marine water-body sustainability at a site of discharge of water into the water-body. Typically, the discharge of water occurs at a discharge of streams, rivers, water purification plants, water desalination plants, power plants, and discharge of oil refineries. The methods provide for daily, quarterly, as well as annual monitoring of water-body quality to ensure sustainability. The methods typically include establishing monitoring sites at a plurality of designated distances from the site of discharge, at a plurality of designated depths at the monitoring sites, and obtaining samples from the water-body at the monitoring sites. Interrogating the obtained samples for physical and chemical monitoring, biological monitoring, biochemical and organic monitoring, microbial monitoring, and phylogenetic analysis, as well as monitoring the sites for marine observational surveys, helps establish the marine water-body sustainability at a site of discharge.
