The denitrification and dephosphorization reactor for the agricultural non-point source nitrogen and phosphorus pollutant treatment is characterized in that when in use:

First, the reactor is moved to the vicinity of the agricultural non-point source polluted water area to be treated by the universal wheels 2 and the straight wheels 3 at the bottom of the frame 1. The inlet pipe 53 is then connected to a source of contaminated water via a flange on the inlet pipe 53, and the outlet pipe 54 is also connected to a subsequent treatment or discharge system via a flange.

When the contaminated water source enters the treatment canister 5 through the inlet pipe 53, it first enters the sedimentation zone. In the settling zone, heavier particulates and impurities begin to sink due to gravity, forming preliminary sediment, thereby relieving the burden of the subsequent processing zone.

Subsequently, the water stream enters the filtration zone. In the filtering section, larger particles and impurities are first removed by the first coarse grille 560 fixed on the lower fixing plate 56. The water flow then continues through the second coarse grille 570, which is fixed to the upper plate 57, for further fine filtration to remove smaller particulate matter. At this time, the water quality is primarily purified, and favorable conditions are created for subsequent biological treatment.

Next, the water flow enters the area of fine grill 58. The fine grid 58 can further intercept fine particles, ensure that the water entering the aerobic reaction zone is cleaner, avoid the interference of the fine particles on the microbial community and improve the biological treatment efficiency.

When water flows into the aerobic reaction zone, the aerator 51 starts to work, and sufficient oxygen is provided to the bottom of the aerobic reaction zone through the aeration pipe 510. Under sufficient oxygen supply, the activity of aerobic microorganisms is enhanced, and nitrogen and phosphorus pollutants in the water body are decomposed, so that the nitrogen and phosphorus pollutants are converted into harmless or low-toxicity substances. Meanwhile, the gas generated in the reaction process is timely discharged through the exhaust hole 52 on the cylinder cover 50, so that the influence of gas accumulation on the reaction effect is avoided.

After the aerobic treatment is completed, water flow enters the anaerobic reaction zone through the communicating pipe 511 between the partition plates 59. Within the anaerobic reaction zone, anaerobic microorganisms begin to act, further decomposing the remaining contaminants in the water body. Due to the effective isolation of the two partition plates 59, the water flow and gas of the aerobic reaction zone and the anaerobic reaction zone do not interfere with each other, and the stable operation of the respective reaction zones is ensured.

The lift pump 512 and the solenoid valve 513 installed on the communication pipe 511 can precisely control the flow rate and the flow rate, adjust the flow path and the treatment time according to the treatment demand, and further optimize the treatment effect.

Finally, the water after precipitation, filtration, aerobic treatment and anaerobic treatment is discharged from the reactor through a drain pipe 54 and enters a subsequent treatment or discharge system. At this time, the nitrogen and phosphorus pollutants in the water body are effectively removed, and the environmental protection emission standard is reached.

In the whole treatment process, the cart handle 4 arranged on the outer wall of the front side of the frame 1 facilitates the movement and operation of equipment, the flange plate is arranged to facilitate the connection and disassembly of the water inlet pipe 53 and the water outlet pipe 54, and the usability and maintainability of the equipment are improved.
