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

Embodiment 1
[0063] Example 1, see Figure 1 to Figure 2 :
[0064] The invention provides a functional green top type sewage regeneration ultra-clean treatment process (see figure 1 ), including the following steps:
[0065] 1) Pretreatment: Sewage passes through grid room C 1 To remove suspended solids, the grille C 1 It is a semi-underground structure, equipped with mechanical grilles 3, the gap between the grilles 3 is 20mm, and the installation angle is 75°; 2 Carry out homogenization and equalization, the adjustment pool C2 There is a mixer 4 and a submersible pump 5 inside;
[0066] 2) Strengthen OAAO treatment: adjust pool C after pretreatment 2 Part of the sewage in the water is sent to the anoxic pool A through the submersible pump 5 and the raw water pipe 6 at the same time. 1 , anaerobic pool A 2 , anoxic pool A 3 , anoxic pool A 4 In the middle, the sewage directly enters the aerobic pool O through the overflow pipe 21 1 , and then through the anoxic pool A 1 and an...

The invention provides a functional green roof type sewage regeneration ultra-clean treatment process, which includes the following steps: the sewage is pretreated first, and the sewage is filtered through a grid C. 1 Remove suspended solids, adjust tank C 2 Homogeneous and homogeneous; the pretreated sewage flows through the aerobic tank O in turn 1 , Anoxic pool A 1 , Anaerobic tank A 2 and aerobic pool O 2 Carry out enhanced OAAO treatment; the sewage after enhanced OAAO treatment flows through anoxic tank A in turn 3 , aerobic pool O 3 , Anoxic pool A 4 , aerobic pool O 4 Multi-stage AO treatment is carried out; the sewage after multi-stage AO treatment flows through the filler-biological composite denitrification filter B in turn 1 and Phosphorus Removal Filter B 2 Carry out ultra-clean treatment; use real-time fuzzy control system to monitor the changes in water quality of incoming and outgoing water, and remotely adjust the internal operating status of the process. The invention adopts a treatment method combining biological, chemical and ecological treatment, and the treated effluent reaches the surface water class IV standard, and has a series of advantages such as shock load resistance, good treatment effect, stable operation and low cost, and is suitable for treatment of domestic sewage. Ultra clean treatment.
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...
