Embodiment

[0069] Such as figure 1 As shown, the embodiment of the present invention provides a modular rural sewage treatment system, which can treat rural domestic sewage. The water quality of the treated domestic sewage is as follows: water temperature=8~25°C, COD≤500mg / L, BOD 5 ≤250mg / L, SS≤200mg / L, NH 4 +-N≤40mg / L, TN≤55mg / L, TP≤6mg / L, pH=6~9.

[0070] Specific treatment methods include:

[0071] (1) Standardized treatment: The sewage is sequentially processed through the pretreatment module, anoxic anaerobic module, two-stage (or multi-stage) anoxic-aerobic module, sedimentation module, depth filtration module and disinfection module of the modularized intelligent rural sewage treatment system. Among them, the pretreatment module is mainly for scum interception and water quality regulation; the anoxic anaerobic module is mainly for denitrification and anaerobic phosphorus release, and organic matter degradation at the same time; two-stage (or multi-stage) anoxic and aerobic The ...

Abstract

The invention discloses a modular intelligent rural sewage treatment system which is characterized in that a pretreatment module is provided with a water inlet end and a water outlet end, and the water outlet end is connected with water inlet ends of an anoxic and anaerobic module and anoxic and aerobic modules at all levels; the anoxic and anaerobic module is sequentially connected with each stage of anoxic and aerobic module, the precipitation module, the deep filtration module and the disinfection module; the dosing dephosphorization module is connected with the precipitation module, and the sludge backflow end of the precipitation module is connected to the bottoms of the anoxic and anaerobic module and the first-stage anoxic and aerobic module respectively; a water outlet end is arranged at the rear end of the disinfection module; the DO analyzer is arranged in the aerobic zone of the last-stage anoxic-aerobic module of the plurality of stages of anoxic-aerobic modules; the intelligent regulation and control early warning equipment is electrically connected with the aeration device of each stage of anoxic and aerobic module, and when conditions are met, the aeration device of each stage of anoxic and aerobic module is started, and aeration or corresponding alarm is carried out according to preset duration. As the device is composed of a plurality of modules, the device is convenient to disassemble, assemble and transport, and the convenience and effect of rural sewage treatment are improved.

Description

technical field [0001] The invention relates to the field of rural sewage treatment, in particular to a modular intelligent rural sewage treatment system. Background technique [0002] At present, my country's rural decentralized sewage treatment processes mainly include: ecological treatment process, biological treatment process and combined process; ecological treatment process includes stabilization pond, artificial wetland and land treatment process; biological treatment process includes septic tank, anaerobic process , Ordinary activated sludge method, AO / A2O method, biological turntable, biological contact oxidation method, SBR method, etc., and the more popular MBR process now; the combined process includes ecological combination, biological combination and their mutual combination process. Among them, septic tank and biological anaerobic technology are mostly used in rural areas. However, these scattered rural sewage treatment processes are still unable to meet the c...
