Embodiment Construction

[0043] Such as Figure 1 to Figure 3 Shown, be a kind of sequencing batch type sewage treatment method of the present invention, comprise the following steps:

[0044] 1) Sewage filtration treatment:

[0045] (1) The sewage is transported to the filter tank through the water pump, first enters the first filter area 1, and is filtered by the coarse grid 4 and the fine grid 5 to remove the suspended impurity particles in the sewage, and then enters the second filter Further filtration treatment is carried out in Zone 2;

[0046] (2) The sewage enters the bottom of the second filter area 2 through the delivery pipe 20, and then passes through the triple filtration treatment of the cobblestone layer 6, the crushed stone layer 7 and the biological filler layer 8 from bottom to top, and the filtered upper sewage is discharged from the second filter area. The upper part of the second filter area 2 enters the third filter area 3;

[0047] (3) The sewage that enters the third filter...

Abstract

The invention discloses a sequencing-batch sewage treatment method. The sequencing-batch sewage treatment method comprises the following steps: (1) sewage filtration treatment, (2) sewage adjustment treatment, (3) sewage aeration treatment, (4) sewage disinfection treatment and (5) sewage disinfection treatment. The sequencing-batch sewage treatment method has the beneficial effects that the structure is simple, the practicability is strong, the treatment manner is simple, the efficiency is high, and the treatment and reuse of sewage are realized; and meanwhile, by carrying out buffering and thermal refining on the sewage through an adjustment pond, the flow fluctuation caused when the sewage enters the subsequent treatment devices is reduced, so that the treatment of the sewage is relatively scientific.

Description

technical field [0001] The invention relates to a sequential batch sewage treatment method. Background technique [0002] In today's society, industrial technology is developing rapidly, and a large amount of waste water is also produced. Moreover, many industrial and domestic wastewater are directly discharged into the river without treatment, which will cause serious pollution to the river. Therefore, the wastewater discharged into the river must be treated and discharged only after passing the standard. With the development of the economy and the improvement of people's awareness of environmental protection, people are paying more and more attention to the treatment of sewage. [0003] Sequential batch sewage treatment is to complete the five processes of water intake, reaction, sedimentation, drainage, and standing in one treatment structure, and aeration is still used in the reaction process. This process is more practical for intermittent discharge and sewage with l...
