Abstract: The present disclosure relates to a method for determining a softening temperature of copper and copper alloy, including: selecting a plurality of samples of the same material, annealing the plurality of samples at different temperatures, air-cooling the plurality of samples; measuring the tensile strength of an original sample and the plurality of samples after the annealing; plotting a data of the measured tensile strength into a temperature-tensile strength curve; a temperature at which the tensile strength in the temperature-tensile strength curve drops to a certain value of an original sample tensile strength is the softening temperature of the material. The above technical solution in the present disclosure uses the tensile strength instead of hardness to measure the softening temperature. It can effectively improve the detection efficiency and reduce the cost, and can be widely used in determination of the softening temperature of fine materials of copper and copper alloy.

Abstract: A sewage/wastewater biological treatment system—sewage (wastewater) synergistic treatment acceleration device, which includes four components of a reaction assembly, a signal transmission assembly, a control assembly, and a housing carrying assembly. The reaction assembly can realize the colonization/proliferation of functional microorganisms, participate in the interface electron transfer between the electrode-microbe-sewage as an electron donor/receptor and electrode interface of the (bio)electrochemical reaction, and optimize the flow characteristics in the sewage/wastewater treatment system. The signal transmission assembly enables the conduction of applied voltage and real-time signal acquisition and transmission of key parameters. The monitoring assembly implements intelligent controllability of the present invention. The housing carrying assembly enables integrated assembly of single device and multi-device serial/parallel operation assembly.
