Problems solved by technology

The device adjusts the volume of the reaction pool by adjusting the number of separate pools. The number of separate pools is large, and the reactor occupies a large area. In addition, the reactor is equipped with a water outlet at the bottom of the partition, which is easy to make the pollution of different reaction pools The mud is mixed with each other, which affects the treatment effect of different sections

Embodiment 1

[0031] The biochemical reactor of the invention is used for a separate denitrification process.

[0032] The conversion of nitrogen in the biological denitrification process of sewage mainly includes nitrification and denitrification, in which nitrification is carried out under aerobic conditions, and denitrification is carried out under anoxic conditions. First of all, close all the non-return water-passing plates on the partitions 1 and 5 with the bolts, open the water-passing holes of the aerobic tank and the sedimentation tank 2, and close the other water-passing holes, so that the sewage passes through the water-passing holes of the aerobic tank It enters through the mouth and exits through the water outlet of the sedimentation tank 2. Due to the function of the non-return water filter, the sewage overflows in a clockwise direction, that is, flows through the aerobic tank-sedimentation tank 1-anoxic tank-sedimentation tank 2 in sequence. Sewage enters the aerobic tank at...

Embodiment 2

[0035] The biochemical reactor of the invention is used for a separate phosphorus removal process.

[0036] The most basic principle of biological phosphorus removal is to use the characteristics of anaerobic phosphorus release and aerobic phosphorus uptake by phosphorus-accumulating microorganisms in an anaerobic-aerobic or anaerobic-anoxic alternate operation system to achieve the purpose of phosphorus removal. For this process, the anaerobic tank and the aerobic tank are required, and all the non-return water plates on the partitions 3 and 5 are closed with the plugs, and the water outlets of the anaerobic tank and the sedimentation tank 1 are opened, and the other water outlets are are all closed, so that the sewage enters through the water hole of the anaerobic tank and exits from the water hole of the sedimentation tank 1. Due to the function of the non-return water plate, the sewage overflows in a clockwise direction, that is, the process is anaerobic tank-sedimentation...

Embodiment 3

[0039] The biochemical reactor of the invention is used for the process of denitrification and dephosphorization.

[0040] The ammonification of nitrogen in the biological denitrification process of sewage can be carried out under aerobic or anaerobic conditions, nitrification is carried out under aerobic conditions, denitrification is carried out under anoxic conditions, and biological phosphorus removal requires anaerobic ponds and The joint effect of aerobic tank, then can open the water-passing orifice in anaerobic tank and sedimentation tank 2 at this moment, close other water-passing orifice, make sewage enter by the water-passing orifice of anaerobic tank, by sedimentation tank 2 out of the water hole. Due to the function of the check water plate, the sewage overflows in a clockwise direction, that is, the technological process is anaerobic pond-sedimentation pond 3-aerobic pond-sedimentation pond 1-anoxic pond-sedimentation pond 2. At this moment, all non-return water...

Abstract

The invention discloses an aerobic-anoxic-anaerobic biochemical reactor. The reactor is in a cylinder shape. The center line of the vertical cross section of the reactor is taken as the center, and six partition plates are arranged to divide the interior of the reactor into six reaction units namely an aerobic area, an aerobic settling area, an anoxic area, an anoxic settling area, an anaerobic area, and an anaerobic settling area. Multiple non-return water going plates that can be opened or closed are arranged in the upper part of each partition plate and used to maintain the flow direction of sewage and adjust the volume of reaction areas. The invention also discloses a method utilizing the reactor to continuously process sewage. According to the method, when the concentration of pollutants in one reaction area increases, the non-return water going plates are closed from bottom to top so as to prolong the sewage retention time. According to the quality of sewage, functional units and reaction volumes of the functional units in the reactor can be chosen flexibly, moreover, the active sludge in different reaction sections can be effectively isolated, different pollutants can be degraded efficiently by the reactor, the sewage processing efficiency is improved, and the integral and continuous sewage treatment is realized.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an aerobic-anoxic-anaerobic biochemical reactor and a method for continuously treating sewage, and is especially suitable for decarbonization, denitrification and phosphorus removal of sewage biological methods. Background technique [0002] In recent years, with the continuous deepening of the research on the mechanism of biological nitrogen and phosphorus removal, and the continuous application of various new materials and technologies, there are more and more types of biochemical reactors. Some reaction devices combine anaerobic pools, deficient The oxygen pool and the aerobic pool are connected in series, some reaction devices have the anoxic pool upside down, and some reaction devices have the anaerobic pool and the anoxic pool connected in parallel. For different sewage treatment processes, it is often necessary to change the order of the reaction tanks...
