Problems solved by technology

Therefore, this method has the same advantages and disadvantages as the traditional activated sludge method. The advantage is that the technology is mature and the operation is simple; the disadvantage is that the construction investment is large, sludge bulking is easy to occur, denitrification mainly depends on reflux, the kinetic energy consumption is large, and the aerobic tank occupies Large area and other issues
[0021] (2) Poor water quality
[0022] (3) Large changes in water volume

Example Embodiment

[0080] Embodiment 1 The structure and process of the sewage treatment system of the present invention

[0081] Explained with lifting as the leading process technology, see the structure figure 1 :

[0082] 1. Sewage is collected through the municipal pipe network, and enters the grille pool 2 at the front end of the sewage treatment device from the water inlet pipe 1. The grille pool 2 is equipped with an artificial grille or a mechanical grille 3 to remove the larger possible blockage in the sewage The solid matter of the pump 5 is lifted by self-stirring, and the grid slag is regularly transported out for disposal.

[0083] The sewage treated by the grid 3 enters the adsorption tank 4, and the sewage self-stirring lifting pump 5 is installed in the adsorption tank 4, and the self-stirring lifting pump 5 achieves high water level 6 operation and low water level 7 shutdown. Sewage self-stirring lifting pump 5○ Priority is given to the automatic-stirring sewage pump, which is charac...

Example Embodiment

[0134] Example Newly built small town treatment experiment

[0135] Newly built small towns, the annual average climate is around 18℃, the average minimum temperature in winter is 6~8℃, and the summer is relatively hot. The maximum temperature in July and August is above 35℃. The sewage treatment scale is 5000 tons / day (250 Ton / hour), implemented in two phases. The sewage treatment scale of the first phase is 2500 tons / day (125 tons / hour).

[0136] 1. The sewage is treated by lifting, and the structure units are as follows:

[0137] 1. There are four groups of adsorption tanks, and the process size of a single group is:

[0138] 4.8m×4.8m×4.5m, the pool capacity is 414.72m 3 ;

[0139] 2. There are four groups of anoxic tanks, and the process size of a single group is:

[0140] 4.8m×4.8m×4.5m, the pool capacity is 414.72m 3 ;

[0141] 3. There are four groups of aeration tanks, and the process size of a single group is:

[0142] 7.5m×4.8m×4.9m, the pool capacity is 705.60m 3 ;

[0143] 4. ...

Abstract

The invention belongs to the technical field of environmental protection and particularly relates to an energy-saving and emission-reducing town sewage treatment system. The energy-saving and emission-reducing town sewage treatment system provided by the invention comprises a strengthened pre-treatment system, a self-suction jet biological aerated filter system, a composite fluidized-bed biomembrane reaction tank system, a sludge treatment and refluxing system and a winter heat insulation system and is realized by a sewage lifting technology or sewage self-flowing process. According to the system, a novel anaerobic sewage treatment technology, an activated sludge process and a novel aerobic biomembrane-process treatment technology are organically combined, so that the advantages of small floor area, small investment, low energy consumption and simplicity and convenience in maintenance management are achieved; the sewage treatment system disclosed by the invention can be applied to town sewage treatment, and treated outlet water can stably reach the standard A of first-level standard of discharge standard of pollutants for municipal wastewater treatment plant (GB18918-2002).

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to an energy-saving and emission-reducing urban sewage treatment system. Background technique [0002] The 12th Five-Year Plan for National Environmental Protection (Guo Fa [2011] No. 42), the Party Central Committee and the State Council attach great importance to environmental protection as an important part of implementing the Scientific Outlook on Development and an important part of transforming the mode of economic development. As a fundamental measure to promote the construction of ecological civilization. [0003] At present, the overall deterioration of my country's environmental conditions has not been fundamentally curbed, environmental contradictions are prominent, and the pressure continues to increase. Water pollution in some key river basins and sea areas is serious, atmospheric haze is prominent in some regions and cities, and the discha...
