Abstract: A bidirectional address allocation method and system are used for allocating independent addresses to N units awaiting address allocation of at least one module awaiting address allocation. A first serial data port of a controller, two serial data ports of each of the N units awaiting address allocation, and a second serial data port of the controller are sequentially connected in series. In the module awaiting address allocation, a direction starting from a unit awaiting address allocation connected to the first serial data port of the controller is a forward direction, and a direction from a unit awaiting address allocation connected to the second serial data port of the controller is a reverse direction. The method includes: performing forward address allocation; determining whether address allocation for the N units awaiting address allocation is completed; changing an input/output direction; and performing reverse address allocation.

Abstract: The invention, as a sewage treatment technique, provides a method for improving biological manganese oxidation performance of manganese-oxidizing bacteria and application thereof. By adding biochar, it improves the biological manganese oxidation performance of the manganese-oxidizing bacteria. It can increase the oxidation rate of the divalent manganese after adding the biochar first and the divalent manganese next into the manganese-oxidizing bacteria. The heavy metals, accordingly, in the wastewater could be removed efficiently. The biochar, as an electron shuttle, can prompt the electron transfer and accelerate the oxidation rate of divalent manganese, as well as the gene abundance and expression ability of manganese-oxidizing bacteria and the extracellular superoxide concentration. The biological activity of the manganese-oxidizing bacteria and the oxidation of divalent manganese are enhanced. In addition, the biochar is abundant and low-cost, which may reutilize resources and reduce the treatment cost.
