Embodiment 1
[0025] Such as figure 1 Shown, be the preliminary wastewater treatment system of eutrophic organisms of the present invention, its block diagram is as figure 1 As shown, it includes aerobic bioreactors, oxygenation equipment, and biorotary reactors connected in sequence.
[0026] Among them such as figure 2 The aerobic bioreactor shown is specially designed to improve the microbial cycle characteristics inside the aerobic bioreactor, and is directly connected to the biorotary reactor after passing through the oxygenation equipment, so that it is convenient to pass the microorganisms cultivated in the aerobic bioreactor The microorganisms arrive at the biorotary reactor and are immobilized in order to improve the performance of the biorotary reactor.
[0027] The aerobic bioreactor of the present invention releases tiny oxygen bubbles through the oxygen injection pipe 40 arranged at the bottom, and utilizes the upward movement of the bubbles to guide the material flow throug...

The invention discloses an aerobic organism primary wastewater treatment system comprising an aerobic organism reactor, an oxygen charging device and a rotating biological contactor which are sequentially connected. The aerobic organism reactor comprises a cylinder, a solid-liquid separation area, a second inner circulation area, a first inner circulation area and a complete mixing area are sequentially arranged in the cylinder from top to bottom, a mud collection plate is arranged at the bottom of the complete mixing area, a water inlet pipe and an oxygen spray pipe are arranged above the mud collection plate, the water inlet pipe extends upwards to form a plurality of water inlet branch pipes at the bottom of the complete mixing area, and a first air guide plate, a first mud guide plate and the like are arranged at the top of the complete mixing area. Microorganisms in an aerobic organism fluidized bed can repeatedly circulate between the upper portion and the lower portion of the fluidized bed along an inner circulation path, so that the successively cultured microorganisms with excellent inheritable characters in the fluidized bed can flow to the rotating biological contactor and are fixed, and the wastewater treatment performance of the rotating biological contactor is improved.
Description
technical field [0001] The invention relates to a preliminary treatment system for aerobic biological wastewater, belonging to the technical field of biological wastewater treatment systems. Background technique [0002] In wastewater aerobic biological treatment, common aerobic biological wastewater treatment devices include aerobic biological fluidized bed and aerobic biological disk. [0003] Among them, the aerobic biological fluidized bed has the characteristics of being able to treat wastewater under the conditions of high sludge concentration and high volume load. It has a large specific surface area during biodegradation, and can rapidly and effectively degrade organic wastewater. However, it is still easily affected by the change of wastewater concentration, cannot adapt well to the fluctuation of wastewater, and its treatment capacity is unstable. [0004] Relatively speaking, the biological turntable method has low energy consumption, high biomass, and high effi...
