Modular vertical linkage bioreactor

Abstract

A modular vertical linkage bioreactor comprises an anaerobic tank, a facultative tank, an aerobic tank, a sedimentation tank, a D type filter tank, an ultraviolet sterilization device, a dosing system, a main fan, a reflux pump, an equipment chamber, a PLC (Programmable Logic Controller), electromagnetic valves and a pipeline, wherein the anaerobic tank, the facultative tank, the aerobic tank, thesedimentation tank and the D type filter tank are all prefabricated into a cylinder shape, the dosing system, the main fan, the reflux pump, the PLC and the electromagnetic valves are located in theequipment chamber; and the power supply input ends of multiple electromagnetic valves, the main fan and the reflux pump are respectively connected with multiple power supply output ends of the PLC through leads. The bioreactor can be conveniently combined and installed; the space is saved, seasonal water quantity change impact can be resisted; when the water quantity is small, only one set of thebioreactor is used, and thus the energy is saved. The whole sewage process is adjusted, anaerobic and facultative treatments become similar, the denitrification nitrogen removal effect is enhanced, the bioreactor is suitable for being applied to different areas with unbalanced water qualities, and the problems that the total nitrogen removal rate is low, the carbon source consumption is large, andchemicals are wasted are solved.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a modular vertical linkage bioreactor. Background technique [0002] With the rapid development of industrial and agricultural technology and the improvement of people's living standards, the requirements for water quality are getting higher and higher. Therefore, the construction and transformation of urban sewage treatment equipment and the effective treatment of sewage are becoming more and more important. Monitoring data show that in many rivers (such as the Minjiang River and Tuojiang River in Sichuan, my country), the main pollution indicators are total phosphorus, ammonia nitrogen and chemical oxygen demand. Among them, total phosphorus is the primary indicator that affects the environmental quality of surface water, and total nitrogen is the current sewage. Important indicators that are more difficult to deal with. Currently built sewage treatment plants generall...

Problems solved by technology

[0004] In order to overcome the disadvantages that the existing sewage treatment plants cannot effectively treat the total phosphorus, ammonia nitrogen and chemical oxygen demand in sewage, and that the existing urban sewage treatment is scattered, the water quality is unstable, and the water volume is small. The invention provides a prefabricated shape, which can be conveniently assembled and installed, realizes space saving, standardized size, modularization, splicing, and free combination, and is suitable for urban and rural sewage treatment with small water volume and scattered areas. The combination of bioreactors can resist the impact of seasonal water volume changes, and when the water volume is small, it can be used in a single group to achieve the purpose of energy saving, adjust the overall process of sewage, and realize the "blurring of boundaries" between anaerobic and facultative oxygen (referring to Under different water quality conditions, by adjusting the dissolved oxygen content in the pool, it can realize the alternation of anaerobic and facultative pool body functions), strengthen the denitrification and denitrification effect, adapt to the regional application of different water quality imbalances, and prevent the total nitrogen removal rate from being biased. Low, large amount of carbon source dosage, waste of chemicals and other issues, thus achieving a modular vertical linkage bioreactor that can effectively treat total phosphorus, ammonia nitrogen and chemical oxygen demand in sewage
