Abstract

The invention discloses a circular sewage treatment system. The circular sewage treatment system comprises a cooling pond, a precipitation separation tank, a first reaction tank, a second reaction tank, a third reaction tank, a filtering basin and a settling pond which are connected by a pipeline; filler is putted in the first reaction tank and is used for removing coarse oversize particles and suspended matters; suspended matters which cannot be sunk and soluble biodegradable organic matters in the second reaction tank are removed by using a sewage biochemical treatment method; the third reaction tank is used for denitriding and dephosphorizing deep treatment of the sewage. The circular sewage treatment system disclosed by the invention has the characteristics of simple structure, capability of meeting the demands under multiple conditions, wide application range, high treatment efficiency and convenience in use.

Description

technical field [0001] The invention relates to the field of sewage treatment systems, in particular to a circulating sewage treatment system. Background technique [0002] The level of economic development in my country varies greatly from place to place, and cities with lagging economic development cannot spend a lot of funds on sewage treatment. Therefore, how to use limited funds to reduce environmental pollution is a problem faced by many city governments. In terms of sewage treatment, until not long ago, some cities still adopted the first-level or first-level enhanced treatment technology, and the effluent could not meet the requirements of the national second-level discharge standard for the removal of organic pollutants. The cyclic intermittent aeration process fully utilizes the advantages of high-load oxidation ditch and high treatment efficiency, and makes full use of the characteristics of good effluent of the sequencing batch activated sludge sewage treatment p...
