[0002] Organic pollution refers to pollutants composed of natural organic substances in the form of carbohydrates, proteins, amino acids and fats, as well as some other biodegradable synthetic organic substances. It can be divided into two categories: natural organic pollutants and synthetic organic pollutants. Organic pollution is very harmful to humans, but some measures can be taken to remove or reduce the harm.

[0003] When soil is polluted by organic matter, the in-situ organisms in the soil are easily damaged and need to be repaired. A common method is to use the nozzles on the infusion pipe to irrigate the contaminated land. Since the nozzles on the infusion pipe are arranged at intervals, there are dead corners for irrigation in the areas between the nozzles, which makes the contaminated land unevenly irrigated. In order to solve the above problems, a bioremediation device with more uniform irrigation is proposed. Utility Model Content
