This utility model relates to a wastewater treatment device for chloroamine production, belonging to the field of wastewater treatment technology. It includes a treatment tower with a dividing funnel in the upper middle part that separates it into an upper aerobic zone and a lower anoxic zone. The upper aerobic zone contains multiple fluidized bed packings, and an effluent weir is located at the top of the upper aerobic zone. An overflow pipe is located on the outer side of the bottom of the effluent weir on the treatment tower, connecting to the lower anoxic zone. The lower anoxic zone consists of a biological packing layer, a filter layer, and a filter plate from top to bottom. An effluent pipe is located at the bottom of the treatment tower. This utility model integrates the upper aerobic zone and the lower anoxic zone vertically within the treatment tower, significantly saving floor space. After entering the treatment tower, the wastewater first undergoes nitrification in the upper aerobic zone under aeration, and then overflows through the effluent weir into the lower anoxic zone, where denitrification occurs due to the anaerobic bacteria on the biological packing layer. This ensures more thorough contact between microorganisms and water, resulting in higher wastewater treatment efficiency.

Cyclic dinucleotides (CDRs) are signaling molecules for cancer therapy, acting as second messengers for intracellular events initiated by GPCR activation and stimulating factors for the interferon gene (STING), thus significantly influencing tumor suppression. Simultaneously, when cancer occurs in a subject, angiogenesis and cell growth proceed at very high rates in vivo, creating a hypoxic environment due to incomplete angiogenesis in cancerous tissue. This environment can be highly conducive to the proliferation of anaerobic bacteria such as Salmonella strains or Escherichia coli. Therefore, this invention relates to a DNA construct incorporating a gene encoding an enzyme for synthesizing cancer therapeutic signaling molecules (e.g., CDRs), or to strains transformed with a vector containing the DNA construct. According to the invention, the DNA construct or strains transformed with a vector containing the DNA construct target cancer in a subject and then secrete C-di-AMP or C-di-GMP synthases in the surrounding environment of the cancer, thus enabling highly effective prevention or treatment of cancer while allowing for real-time cancer diagnosis.
