Embodiment Construction

[0019] see figure 1 , 2 with image 3 , The integrated treatment equipment includes a pool body 1, a water inlet pipe 2 and a drain pipe 3, etc. The pool body 1 adopts a circular pool body, which is composed of four concentric circles, and divides the pool body into four functional areas: the outer ring 4 is divided into different reaction areas by a partition 14, and a semi-soft composite packing 8 is arranged inside, each The aerobic and anoxic alternate operation in the reaction zone, each reaction zone is connected with the water inlet pipe 2, water supply in points, and set to the water outlet pipe 15 in the middle ring. The middle ring 5 is an aerobic zone with a semi-soft composite packing 8 and a water outlet 16 to the inner ring. An underwater aeration device 10 is arranged at the bottom of the outer ring 4 and the middle ring 5 . The inner ring is the sedimentation area 6, which is equipped with inclined plates 9 (the length of the inclined plates is 0.5m, the di...

Abstract

The invention discloses an integral multistage biological membrane wastewater treating device, comprising tank, filling material, influent pipe and exhaust pipe. The said tank comprises a quaternary concentric circle, and the outer circle is separated into different reaction areas by baffle board with alternative operation of aerobic and anaerobic, semi-flexible composite filling material is equipped in every reaction area, the intermediate circle is filled with semi-flexible composite filling material, the inner circle is the settling area and the center is the sterilizing area. The said influent pipe is connected with the reaction areas of the outer circle, and supplies water in point, the reaction areas of the outer circle is connected with intermediate circle, inner circle and central sterilizing area in order through water pipe, the exhaust pipe is connected with the central sterilizing area to extends out and the underwater aerator is installed in the bottom of the outer circle and intermediate circle. The device is characterized by the resistance to impact load, high treating effect, low running energy consumption, small surplus sludge, short process, little accommodation area, low investment and convenient management.

Description

Technical field: [0001] The invention belongs to the technical fields of sewage treatment and environmental protection, and in particular relates to an integrated multi-stage biofilm method sewage treatment equipment. Background technique: [0002] At present, there are no reports about integrated multi-stage biofilm sewage treatment equipment at home and abroad. At present, in sewage treatment technology, the general sewage nitrogen and phosphorus removal process is A 2 / O and its various improved forms, all of which require nitrifying liquid and sludge return equipment to meet the requirements of nitrogen and phosphorus removal. In practical engineering applications, the process is complicated, there are many reactor units, the operation is cumbersome, the cost is high, and the effect of nitrogen and phosphorus removal is difficult to further improve. Invention content: [0003] Aiming at the deficiencies of general phosphorus and nitrogen removal reactors, the present...
