The invention relates to a treatment system and treatment method for high-efficiency degradation and denitrification of aquaculture wastewater, including a regulating tank, a grit chamber, a feeding tank, an anaerobic reactor, a pre-oxidation-nitrosation integrated tank, and anaerobic ammonium oxidation Reactor and effluent reflux pool, the anaerobic reactor is an anaerobic internal circulation reactor, the waste water flows through the outer ring pool cavity and then enters the inner ring pool cavity, and the anaerobic ammonium oxidation reactor is an upflow anaerobic reactor Oxygen packing tower, aquaculture wastewater undergoes purification reactions through the above structures in sequence, and undergoes hydrolysis, sand removal, anaerobic, nitrosation, anaerobic ammonia oxidation and other reactions respectively. After multi-stage degradation treatment, harmful pollutants in wastewater can be efficiently removed. The present invention combines the anaerobic process and the anaerobic ammonium oxidation process, firstly removes COD through anaerobic process, and then denitrifies through the anaerobic ammonium oxidation process, so as to realize efficient removal of high-concentration pollution components in aquaculture wastewater, and the process is easy to operate and stable in operation.

The invention discloses an internal circulation reactor and method for continuously preparing phosphorus pentafluoride. The internal circulation reactor comprises a cylinder body with a heat exchange jacket, wherein planar end closures are arranged at the upper and lower ends of the cylinder body, and a concentric inner cylinder body is arranged in the cylinder body; the upper end closure is provided with a mixed gas leading-out pipe; the lower end closure is provided with a three-way gas intake pipe; and a reaction solution eduction pipe and a feed liquid ingress pipe are arranged on the cylinder body. The process of preparing phosphorus pentafluoride comprises the following steps: blowing the reactor with an inert gas; creating a low temperature environment of the reactor with a refrigerant; adding a phosphorous pentachloride solution, anhydrous hydrogen fluoride and the inert gas to the reactor for reaction; and continuously leading out mixed gas containing phosphorus pentafluoride and part of a low-concentration phosphorous pentachloride solution, and at the same time continuously adding a phosphorous pentachloride concentrated solution, anhydrous hydrogen fluoride and the inert gas to realize continuous operation. The internal circulation reactor and method for continuously preparing phosphorus pentafluoride have the advantages that the concentration stability of reactants in the reactor can be maintained, and continuous production and automatic control of phosphorus pentafluoride are realized.

The invention discloses an internal circulation reactor for tritium removal of water. The internal circulation reactor comprises a top cover, an outer cylinder, a central area air inlet pipe, an annular gap area air inlet pope, a sintering plate, a flow guide cylinder, theta-ring filler, a tritium-containing water inlet pipe, a tritium-containing hydrogen exhaust pipe, an annular pipe type distributor and a low-tritium water outlet pipe. The top cover is arranged on the top of the outer cylinder, the annular pipe type distributor is located inside the outer cylinder, the tritium-containing water inlet pipe and the tritium-containing hydrogen exhaust pipe are both communicated with the outer cylinder, and the tritium-containing water inlet pipe is connected with the annular pipe type distributor. The bottom space in the outer cylinder is divided into a central area and an annular gap area by the glow guide cylinder, wherein the central area is communicated with the flow guide cylinder, and the annular gap area is communicated with the bottom of the outer cylinder. The sintering plate is fixed inside the outer cylinder. The central area and the annular gap area are filled with the theta-ring filler. The low-tritium water outlet pipe is communicated with the annular gap area. The internal circulation reactor has the advantages of being large in gas-liquid phase contact area and high in reaction efficiency, and tritium-containing water can flow in a fixed direction; meanwhile, the standing time of the liquid phase can be controlled, and thus the content of gas-phase tritium and the content of liquid-phase tritium after a reaction can be quickly and accurately controlled.
