Abstract: The invention relates to a tube bank heat exchanger for use in reducing the temperature of air delivered under pressure to an air diffuser system within a wastewater treatment facility. The tube bank heat exchanger, submerged within the wastewater, is of a configuration which extends the air flow path from the air source to the diffuser system. By such configuration the temperature of the air delivered to the diffuser system is reduced to a temperature of no more than about 140 degrees F.

Abstract: A device for treating uranium tailings with microorganism is provided and includes a treatment container, a spray water distribution assembly, a microbial incubator and a first pump. The water is transported from the microbial incubator to the spray water distribution assembly through the first pump, allowing the microorganisms to enter the interior of the uranium tailings in the treatment container. After treatment is completed, the water is collected by the water collection cylinder and sent back to the microbial incubator for recovery, so as to reduce the waste of microorganisms. The even distribution of horizontal spray pipes can evenly spray water containing microorganisms on the uranium tailings in the treatment container, which makes the distribution of microorganisms in the uranium tailings more uniform and can prevent inadequate treatment and improve the treatment efficiency of microorganisms on uranium tailings.

Abstract: The disclosure relates to a staggered electrode bio-electro-Fenton groundwater circulation well system, including a groundwater circulation well, a water pumping and injecting assembly and an in-well bio-electro-Fenton assembly. The water pumping and injecting assembly is configured to realize water pumping and injection between different screening sections of the groundwater circulation well. The bio-electro-Fenton assembly arranged in a first screening section of the groundwater circulation well includes at least one electrode device. A cathode and an anode of the electrode device form a spatially staggered arrangement according to different distribution areas. According to the disclosure, the spatially staggered arrangement of the cathode and the anode, the influence of oxygen on an anaerobic environment of an anode chamber in the electrode device is greatly reduced while ensuring the cathode takes oxygen as an electron acceptor, and the constructed bio-electro-Fenton system can accelerate the decomposition of organic pollutants in the groundwater circulation well.

Abstract: The invention discloses a method for enhanced denitrification and a device thereof. The device comprises an anoxic tank, an aerobic tank and a carbon source booster connected in sequence, and an output end of the carbon source booster is then connected with the anoxic tank; a plurality of membrane contactors are fixed inside the carbon source booster, the membrane contactor is in a hollow structure, and there is a gap between the membrane contactors and a shell of the carbon source booster. By adopting the device, macromolecular carbon source can be added and hydrolyzed into volatile fatty acids by using the hydrolytic fermentation bacteria existing in the gap between the carbon source booster and the membrane contactors, which then penetrates into the hollow part of the membrane contactors through membrane diffusion, as a small molecular carbon source that can be effectively used by denitrifying bacteria to promote the denitrification process.

Abstract: A method, apparatus, and system are provided, utilize a floating treatment wetland designed specifically for the sequestration of microplastic debris (i.e., plastic particles under 5 mm) from active water systems. This process can be achieved through the careful selection of a root structure combined with the development of a robust housing for the wetland pad, so that it may operate effectively in fast current conditions. Existing phytoremediation wetlands are typically deployed in static aquatic environments like reservoirs or lakes, and cannot remain stable in currents beyond speeds of 2 m/s. This currently limits their application in most rivers that typically reach speeds beyond 6 m/s, especially during storm surges. To overcome this, disclosed is a hydrodynamic fiberglass frame to encase and stabilize the floating treatment wetland during storm surges. The design of this frame may be adapted to encourage optimal flow to the underside of the wetland, in order to maximize the amount of water exposed to the wetland's biofilm filter.
