Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a bioreactor for wastewater treatment. Background Art

[0002] Wastewater refers to water bodies containing various pollutants generated in production, life, agriculture and other activities. There are many types of pollutants in wastewater, including organic matter, nitrogen, phosphorus, heavy metals, microorganisms, etc., which pose potential hazards to the environment and human health. Therefore, wastewater bioreactors are needed for reaction treatment. Wastewater bioreactors are equipment that uses microorganisms to degrade and transform organic matter and other pollutants in wastewater. Through the metabolic activities of microorganisms, organic matter in wastewater is degraded into harmless substances, or pollutants such as nitrogen and phosphorus are transformed into harmless forms, thereby purifying wastewater.

[0003] After searching, the Chinese patent authorization number CN207511900U discloses a bioreactor for industrial wastewater treatment, including a reaction cylinder, a support, a feeding pipe, a valve, a cylinder cover, an observation window, a base, a stirring mechanism, an extrusion pipe, a bioreactor, and an anti-corrosion sleeve. The reaction cylinder and the base are an integrated structure, the reaction cylinder and the support are welded, the feeding pipe and the cylinder cover are welded, the feeding pipe is provided with a valve, the observation window is connected to the reaction cylinder, the extrusion pipe is embedded and installed in the cylinder cover, the stirring mechanism and the cylinder cover are an integrated structure, the bioreactor is fitted with the anti-corrosion sleeve, the stirring mechanism includes a locking ring, a swivel, a rotating motor, a rotating shaft, and a stirring blade. The rotating shaft is embedded and connected in the swivel, the rotating shaft and the stirring blade are welded, and the locking ring is located below the swivel. A bioreactor for industrial wastewater treatment in the above patent has the following deficiencies: 1. When the device rotates through the stirring blades, the stirring speed will not be too fast in order not to destroy the internal chemical reaction molecules. In addition, the single rotation mode of the stirring blades will drive the internal wastewater to rotate synchronously, thereby affecting the mixing speed of the stirring and affecting the overall progress of the reaction; 2. When the wastewater undergoes biological reaction, a biofilm will be generated to facilitate the decomposition of organic matter, nitrogen, phosphorus and other pollutants in the wastewater. However, if it is not cleaned after use or for a long time, it may affect the operation effect of the bioreactor and even cause problems such as blockage, and there is a lack of internal cleaning structure.
