  • Patent number: 10239774
    Abstract: The field of advanced wastewater treatment, and more specifically, to a natural pyrrhotite biofilter and a method for utilizing same to synchronously remove nitrate-nitrogen and phosphorus from water is provided. The method includes the following steps: (1) preparation of the packing material and construction of the biofilter; (2) start-up of the biofilter; (3) operation of the biofilter. The method disclosed in the present invention on the one hand takes pyrrhotite as the electron donor to help sulfur-based autotrophic denitrifying bacteria reduce nitrates into nitrogen gas, and on the other hand utilizes pyrrhotite and its oxidates to eliminate phosphorus through adsorption and chemical precipitation. Therefore, this method realizes synchronous removal of nitrate-nitrogen and phosphorus in water.

  • Patent number: 7894090
    Abstract: A method for ensuring reliable transmission of a DCN signal by a gateway is disclosed. When acting as a sending gateway, the gateway packs a DCN signal detected into an IFP packet and sends the IFP packet to the IP side, then, reports a fax end event to a Soft Switch after a designated delay period; and the Soft Switch issues a State Switching Command for switching the two gateways back to voice state after receiving the fax end event. When acting as a receiving gateway, the gateway modulates a DCN signal detected and sends the modulated DCN signal to a receiving facsimile machine; if a switching command issued by a Soft Switch is received during sending the DCN signal, the gateway delays the switching; if the gateway has not received a switching command after the DCN data is sent, the gateway initiatively reports a fax end event.
