The invention relates to a wastewater treatment device capable of inhibiting sludge bulking and sludge foams. The wastewater treatment device comprises a reaction tank, an ultraviolet lamp arranged above the reaction tank, a self-cleaning assembly comprising a tap water nozzle mounted on the periphery of the ultraviolet lamp, and a reflecting cover arranged above the ultraviolet lamp. Due to the fact that the ultraviolet lamp is arranged above the reaction tank, the ultraviolet lamp has a sterilization effect and mainly can kill hyphomycetes, and the problems of sludge bulking and sludge foams are solved. The self-cleaning assembly can clean the ultraviolet lamp so as to clean sludge, sewage and other sundries, and the reflecting cover reflects ultraviolet rays into the reaction tank. The invention also relates to a wastewater treatment method capable of inhibiting sludge bulking and sludge foams, and the wastewater treatment method comprises the step of performing ultraviolet irradiation on the surface of wastewater, and ultraviolet adopts a UV-C wave band. Through the arrangement of the ultraviolet lamp, the problems of sludge bulking and sludge foams are well solved.
Description
technical field [0001] The present invention relates to a wastewater treatment device and method capable of suppressing sludge bulking and sludge foaming. Background technique [0002] In wastewater treatment projects, in the aerobic aeration of biochemical treatment process, sludge bulking or sludge foaming is often encountered, which will not only cause a large amount of sludge loss, but also make the effluent turbid, and These two problems have always been the troubles often encountered during the aerobic operation of the wastewater station, leading to the deterioration of the effluent. In severe cases, it will cause the collapse of the biochemical system. Contents of the invention [0003] The object of the present invention is to provide a wastewater treatment device capable of suppressing sludge bulking and sludge foaming, which solves the problems of sludge bulking and sludge foaming. [0004] In order to achieve the above object, the technical scheme adopted in th...
