The invention relates to a pond circulating aquaculture water treatment system. The pond circulating aquaculture water treatment system comprises a biological purification tank arranged at a central position of an aquaculture pond, wherein a separation well is arranged at a central position of the biological purification tank; a lifting pump is installed in a circulating pump well at a central position of the separation well; the pond circulating aquaculture water treatment system further comprises an ultraviolet disinfection well arranged on an outer side of a biological purification tank wall; an inner end of an embedded water outlet transverse pipe below a foundation slab of the aquaculture pond is connected with a water outlet inner longitudinal pipe, and an outer end is connected with a water outlet outer longitudinal pipe; an upper end opening of the water outlet inner longitudinal pipe is located in the disinfection well and a water outlet of the water outlet outer longitudinal pipe is located below a liquid level of an outer edge of the aquaculture pond; a sump pit is arranged at a central position of the foundation slab of the aquaculture pond and the sump pit is connected with a blow-down pipe; a separation well blow-down pipe is installed between the separation well and the sump pit. Circulating water filtration, biological purification and ultraviolet disinfection treatment are completed in the aquaculture pond, pump power is needed only in a return water lifting process, no power is needed in other circulating and blow-down processes, the power consumption is reduced and the water treatment efficiency is improved.

A cost-effective and expeditious method for attaching a water channel layer to lath pre-installation, for subsequent application to an inner wall structure, increasing the efficiency and decreasing the cost of building construction, and also encompasses the stock material made thereby. In one form, there is a stapling frame equipped to be placed in juxtaposition to a water channel layer atop a layer of lath on and adjacent surface. A plurality of staplers mounted to the frame then combine the water channel layer and lath to form an integrated stock material that can then be used in a wall structure.
