Abstract

The invention discloses a sewage treatment apparatus for environmental engineering. The structure of the apparatus comprises a sewage treatment tank top cover, treatment tank ladders, a sewage pretreatment tank, a treatment tank pedestal, a sewage treatment device and a sewage sedimentation tank, the right side of the sewage treatment tank top cover is connected with the top end of the treatment box ladder in a welding manner, the lower side of the sewage treatment tank is attached to the upper side of the treatment tank pedestal, and the sewage treatment device is arranged at and welded to the left side of the sewage sedimentation tank. A series of transmissions in the sewage treatment device makes the sewage treatment device dosed regularly, a stirring rack and bottom stirring teeth accelerate the neutralization of a medicament and sewage and improve the efficiency and the rate of a chemical phosphorus removal reaction in order to achieve sewage discharge standards, and air circulation in the sewage treatment device increases the oxygen supply, accelerates sewage treatment and shortens the sewage treatment time.

Description

technical field [0001] The invention relates to a sewage treatment device for environmental engineering, which belongs to the field of sewage treatment equipment. Background technique [0002] Sewage treatment equipment is an industrial equipment that can effectively treat domestic sewage and industrial wastewater in urban areas. It prevents sewage and pollutants from flowing directly into waters, which is of great significance for improving the ecological environment, improving urban quality and promoting economic development. [0003] However, a sewage treatment device for environmental engineering in the prior art uses the traditional activated sludge method for sewage treatment, but it needs a large amount of oxygen and oxygen supply during work, and the sewage treatment time is often prolonged due to insufficient supply, and the phosphorus removal efficiency is low. Low, resulting in high phosphorus content in sewage that did not meet the discharge standard. Contents ...
