The embodiment of the invention discloses a sewage treatment system by adopting an improved activated sludge method. The sewage treatment system comprises a biochemical aeration tank, a settling tank and an aeration backflow system, wherein the aeration backflow system comprises a sludge tank and an aeration backflow device; the aeration backflow device is arranged in the sludge tank; and the aeration backflow device is provided with a diffusion pipe for simultaneously feeding air and sludge flow in the sludge tank into the biochemical aeration tank. The conventional sewage treatment system by adopting the activated sludge method is substantially improved; the sludge backflow system and the aeration system are integrated into a whole; on the basis that the aeration efficiency is not reduced, the engineering investment and the operating cost are effectively saved; moreover, the aeration backflow device of the treatment system adopts lifting design, so that the shortcomings that off-the-line is required when the conventional aeration head is overhauled, and the normal running of a clean pool is influenced are effectively overcome; and the sewage treatment system is easily and conveniently maintained.
Description
Technical field [0001] The invention involves the field of sewage treatment and specially involves a activated sludge sewage treatment system. Background technique [0002] At present, with the development of society and the economy, the country's requirements for environmental protection are getting higher and higher, and the sewage treatment industry is facing more severe challenges.The active sludge method, as a very widely used process in the field of sewage treatment, is increasingly glowing with new vitality.The active sludge method is a sewage biological treatment method based on active sludge as the main body.The traditional activated sludge sewage treatment system includes biochemical ponds, sedimentation tanks, sludge tanks, sludge backflow systems and aeration system.The sludge return system and the aeration system are two separate power consumption systems. The aeration device is generally composed of a fan, aeration head and pipeline. It is necessary to build a separ...
