Embodiment Construction

[0019] see figure 1 , 2 , The reactor has 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 three concentric circles, and divides the pool body into an outer ring reaction zone 5 , an inner ring reaction zone 6 and a central reaction zone 7 . The outer ring reaction zone 5 is divided into two sub-reaction zones by a rectification plate 13 : a rectification zone 14 and an upflow reaction zone 15 . There is a water distribution tank 4 on the top of the rectification area 14, and the bottom of the tank is evenly provided with water holes for evenly distributing water. Water holes are provided at the bottom of the rectifying plate 13 to connect the rectifying area 14 with the upflow reaction area 15 of the outer ring. A baffle 9 is set between the outer ring reaction zone, the inner ring reaction zone and the central reaction zone, and each zone is connected through the water hole provided at the botto...

Abstract

The invention discloses a baffling composite hydrolytic acidifying reactor to request to protect peripherial water, which comprises the following parts: pond, fill, inlet pipe and outlet pipe, wherein the pond is composed of three-grade concentric circle with inlet pipe connecting outer-race distribution groove; the distribution groove is set along circumference with water hole on the groove bottom evenly to supply water; the water passes the distribution hole on the commutating board bottom, which is baffled into outer-race, inner-race and middle reacting regions; the reacting region bottom is floating sludge bed with middle region as half flexible fill region, which intercepts most of solid suspension and colloidal matter in the effluent; the solid organics is decomposed into soluble organics and decomposed further; the vent pipe is laid on the outlet groove bottom of middle reacting region, which contains outlet water.

Description

Technical field: [0001] The invention belongs to the technical fields of sewage treatment and environmental protection, and in particular relates to a hydrolysis acidification reactor. Background technique: [0002] At present, in sewage treatment technology, the general hydrolytic acidification process is UASB and its various improved forms, all of which require the laying of complex water distribution systems to ensure uniform water distribution and full contact between sewage and sludge. In practical engineering applications, the water distribution system of the traditional hydrolysis and acidification process is complex, and the water distribution pipeline is prone to blockage, resulting in short flow and channel flow, resulting in a decrease in treatment efficiency. Invention content: [0003] Aiming at the deficiencies of general hydrolysis acidification reactors, the present invention designs a peripheral water distribution baffle composite hydrolysis acidification ...
