Embodiment Construction
[0024] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
[0025] The method for treating high-quality recycled water according to an embodiment of the present invention will be described below with reference to the accompanying drawings. like figure 2 As shown, the high-quality recycled water treatment method according to the embodiment of the present invention comprises the following steps:
[0026] A) Perform aeration and sand settling on municipal sewage. Through aeration and grit settling of municipal sewage, not only can most of the inorganic particles in the municipal sewage be removed, but also the organic matter adhering to the inorganic particles can enter the municipal sewage, thereby increasing the organic...

Abstract
The invention discloses a high-quality regenerated recycle water treatment system and method. The high-quality regenerated recycle water treatment system comprises an aerated grit chamber, a biological treatment section, a sedimentation tank, a sludge decomposition tank, an ozone generator, a high-density sedimentation tank and an ultrafiltration membrane tank, wherein the biological treatment section comprises a pre-anoxic zone, an anaerobic zone, a front anoxic zone, an aerobic zone, a rear anoxic zone and an aeration zone, water inlets of the pre-anoxic zone, the anaerobic zone and the rear anoxic zone are communicated with a water outlet of the aerated grit chamber, and a water outlet of the aerobic zone is communicated with a water inlet of the front anoxic zone; a sludge outlet of the sedimentation tank is communicated with a sewage inlet of the pre-anoxic zone; a sewage inlet of the sludge decomposition tank is communicated with a sewage outlet of the sedimentation tank, a sludge dissolved cell product outlet of the sludge decomposition tank is communicated with the front anoxic zone. The high-quality regenerated recycle water treatment system has the advantages that the treatment effect is good, the operation cost is low and the like and is mainly suitable for the municipal sewage treatment field.
Description
technical field [0001] The invention relates to the field of municipal sewage treatment, in particular to a high-quality recycled water treatment system and a high-quality recycled water treatment method. Background technique [0002] With the development of society and economy, the consumption of fresh water continues to increase, and water resources are increasingly scarce. However, the amount of sewage discharge is increasing, and the problems of water resources and environmental pollution are very serious. Sewage regeneration and recycling has become the key to solving the shortage of fresh water resources. The A-level discharge standard in Table 1 of the "Water Pollutant Discharge Standard for Urban Sewage Treatment Plants" (DB11 / 890-2012) has the same main index requirements except TN as the surface water quality standard of Class III water body, and the effluent that meets the standard can be directly Reuse as recycled water. [0003] The "Water Pollution Prevention ...
