Functional green roof type sewage regeneration ultra-purifying treatment technology

Abstract

The invention provides a functional green roof type sewage regeneration ultra-purifying treatment technology. The technology comprises the following steps: pre-treating sewage in advance, removing suspended solids through a grating chamber C1 and homogenizing through a regulating reservoir C2; guiding the pretreated sewage to flow by an aerobiotic pond O1, an anoxic pond A1, an anaerobic pond A2 and an aerobiotic pond O2 in turn, for performing enhanced OAAO treatment; guiding the sewage after enhanced OAAO treatment to flow by an anoxic pond A3, an aerobiotic pond O3, an anoxic pond A4 and anaerobiotic pond O4 in turn, for performing multi-level AO treatment; guiding the sewage after multi-level AO treatment to flow by a filler-biological compound denitration filter chamber B1 and a phosphorous removal filter chamber B2 in turn, for performing ultra-purifying treatment; adopting a real-time fuzzy control system for monitoring quality change of entering and discharged water and remotely adjusting internal running state of the technology. A treatment method with a combination of biological, chemical and ecological treatment is adopted by the invention; the treated discharged waterreaches surface water IV-class standard; the functional green roof type sewage regeneration ultra-purifying treatment technology has a series of advantages of resistance to impact load, good treatmenteffect, running stability, low cost, and the like, and is suitable for ultra-purifying treatment of domestic wastewater.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a functional green-top sewage regeneration ultra-clean treatment process. Background technique [0002] At present, the problem of sewage treatment has been widely concerned by the society, and a large number of sewage treatment technologies continue to emerge. The discharge standards of the existing sewage treatment plants in my country refer to the first-class A standard in the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" (GB18918-2002). However, with the development of the economy and the improvement of people's living standards, the requirements for sewage treatment are also constantly increasing. Therefore, it is an inevitable trend for future development to carry out advanced treatment of sewage and achieve a higher standard of effluent after treatment. [0003] The AAO process is composed of anaerobic zone, anoxic zone, aerobic zone, sediment...

Problems solved by technology

Packing adsorption mainly removes pollutants in sewage through physical and chemical effects such as packing adsorption, but often the adsorption capacity of the packing is not high and needs to be replaced frequently. The replaced packing needs to undergo a series of treatments to achieve regeneration, and the regeneration process will Waste liquid is generated, and waste liquid needs to be treated
