The invention discloses a treatment system for domestic sewage. The treatment system comprises an adjusting tank, a biological carbon filter pond, a membrane pool and a disinfecting tank; a water inlet pipe is sequentially connected to the adjusting tank, the biological carbon filter pond, the membrane pool and the disinfecting tank and then is connected with a water outlet pipe; the biological carbon filter pond is divided into an anaerobic zone and an aerobic zone; water from the adjusting tank is connected to the anaerobic zone through a pipeline; the aerobic zone is connected with the membrane pool through a pipeline; a blower is connected to an aeration branch pipe A in the aerobic zone through an aeration pipe. The treatment system disclosed by the invention has the advantages that the treatment of the sewage is more thorough; the biological carbon filter pond comprises an anaerobic zone and an aerobic zone and is small in occupied area; the aerobic zone adopts a biochar filler, so that a good effect of decomposing pollutants is realized; in addition, an air heating device is arranged on an aeration main pipe and provides a suitable living environment for aerobic bacteria; a membrane bioreactor is characterized in that by design of a base plate and waterproof cloth, membrane components can define an impervious area, so that offline cleaning is very convenient.
Description
technical field [0001] The invention relates to a treatment system for domestic sewage, which belongs to the technical field of environmental protection engineering. Background technique [0002] Urban domestic sewage treatment technology can be divided into primary, secondary and tertiary treatment processes according to the degree of treatment. Primary sewage treatment applies physical methods, such as sieving, sedimentation, etc., to remove undissolved suspended solids and floating substances in sewage. The secondary treatment of sewage is mainly the application of biological treatment methods, that is, the process of material transformation through the metabolism of microorganisms, to oxidize and degrade various complex organic substances in sewage into simple substances. Biological treatment has certain requirements on sewage water quality, water temperature, dissolved oxygen in water, pH value, etc. The tertiary treatment of sewage is based on the primary and seconda...
