Embodiment Construction

[0021] see figure 1 , figure 2 , image 3 with Figure 4 The high-efficiency combined anaerobic biological treatment system for treating high-concentration organic wastewater includes two sets of high-efficiency composite anaerobic reactors 1 . A connection pipe 6 is arranged between the outlet pipe 5 of the previous high-efficiency combined anaerobic biological treatment reactor and the water inlet pipe 4 of the latter high-efficiency combined anaerobic biological treatment reactor. A solenoid valve is set, and the individual parallel operation of the reactors and the conversion of the series operation mode are realized by controlling the opening and closing of the solenoid valve 12 .

[0022] Wherein, each reactor all comprises fluidization area 2, baffle biofilm treatment area 3, the water inlet pipe 4 that connects fluidization area, the outlet pipe 5 that is connected by baffle biofilm treatment area, connecting pipe 6 and collector Trachea7. The top of the reactor ...

Abstract

The invention discloses a high-efficiency combined anaerobic biological treatment system for treating high-concentration organic waste water, comprising a plurality of combined anaerobic biological treatment reactors. Each reactor comprises a fluidization area and a biological film treatment area; the fluidization area which is cylindrical is arranged in the center of a biological treatment tank; the bottom of the biological treatment tank is provided with a flow-reflecting hopper; stuffing is arranged in the biological treatment tank, and the top of the stuffing is provided with an inclined plate separation area; the biological treatment tank is encircled around a fluidization bed and comprises an inner ring and an outer ring on the plane; and separation walls are circularly and vertically arranged along the tank body in either circular treatment area and divide the tank body into a plurality of grids which are filled with combined stuffing. The invention has the advantages of strong shockproof loading capacity, high treatment efficiency, strong stability, flexible operation (by connection in series or parallel), strong suitability for the variation of water quality, water quantity and temperature, small floor area, little investment, convenient management, and the like.

Description

technical field [0001] The invention belongs to the technical fields of sewage treatment and environmental protection, and in particular relates to a high-efficiency compound anaerobic biological treatment equipment for treating high-concentration organic wastewater. Background technique [0002] Conventional anaerobic treatment systems for treating high-concentration organic wastewater have disadvantages such as complex treatment processes (usually multi-stage or multi-phase reactors), low operating efficiency, complex operation management, and large floor space. In recent years, the reactor technology for the treatment of high-concentration organic wastewater has developed rapidly. For example, CN1583599 "an anaerobic treatment process for high-concentration organic wastewater" and CN1935698 "an anaerobic treatment process for high-concentration organic wastewater" have been published in Chinese patents. High-efficiency composite anaerobic reactor" and so on, the former is...
