Embodiment 1

[0029] A method for treating domestic sewage in a scenic area, the specific steps are as follows:

[0030] (1) Remove solid impurities from domestic sewage in scenic spots to obtain pretreated sewage;

[0031] (2) use 60 Coγ-ray irradiation pretreatment of sewage, adding hydrogen sulfide scavenger and mullite powder to the pretreatment sewage in turn while stirring, anaerobic fermentation to produce biogas and waste liquid, biogas for subsequent use in scenic spots, waste liquid enters step (3) ;

[0032] (3) The waste liquid generated in step (2) is diverted to the landscape pool for circulation and discharge regularly; wherein, the landscape pool includes upper, middle and lower layers, the thickness of the lower layer accounts for 5 / 8 of the depth of the landscape pool, and the upper layer is floating plants. The middle layer is a planting board, and the planting board is provided with planting holes for fixing floating plants. The root system of the floating plants runs ...

Embodiment 3

[0049] A method for treating domestic sewage in a scenic area, the specific steps are as follows:

[0050] (1) Remove solid impurities from domestic sewage in scenic spots to obtain pretreated sewage;

[0051] (2) use 60 Coγ-ray irradiation pretreatment of sewage, adding hydrogen sulfide scavenger and mullite powder to the pretreatment sewage in turn while stirring, anaerobic fermentation to produce biogas and waste liquid, biogas for subsequent use in scenic spots, waste liquid enters step (3) ;

[0052] (3) The waste liquid generated in step (2) is diverted to the landscape pool for circulation and discharge regularly; wherein, the landscape pool includes upper, middle and lower layers, the thickness of the lower layer accounts for 11 / 16 of the depth of the landscape pool, and the upper layer is floating plants. The middle layer is a planting board, and the planting board is provided with planting holes for fixing floating plants. The root system of the floating plants run...

Abstract

The invention provides a method for treating domestic sewage in a scenic region. A treatment technology is adjusted aiming at characteristics of the domestic sewage in the scenic region and the requirements on the environment of the scenic region, so that effective treatment of the domestic sewage in the scenic region is realized and cyclic utilization of resources is realized; the method mainly comprises the following three steps: Firstly, removing solid impurities to obtain pre-treated sewage; then carrying out deodorization and carrying out anaerobic fermentation to generate marsh gas, so as to realize the cyclic utilization of the resources; finally, draining waste liquid into a landscape pond and circularly flowing; discharging at a fixed period. On one hand, the landscape pond has afurther purification effect; on the other hand, the landscape pond can be used as a viewing spot of the scenic region, the cyclic utilization of the resources is effectively realized, and the method accords with an environment-friendly and sustainable development concept; no odor escapes and the ornamental performance of the scenic region is considered; especially, the method is applicable to thetreatment of the domestic sewage in the scenic region.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a domestic sewage treatment method in scenic spots. Background technique [0002] In recent years, with the improvement of people's living standards, more and more people go out to travel, which brings pollution problems in tourist attractions. Domestic sewage in scenic spots mainly comes from tourist groups, with distinctive characteristics. It generally includes food preparation in scenic spots and excretion of tourists. Among them, dietary preparation in scenic spots is usually relatively simple, mainly fast food, and the amount of sewage generated is limited. Therefore, a large part of domestic sewage in scenic spots comes from bathroom. Taking the construction of 8-10 squatting seats in the scenic area as an example, it can be seen from the design standards of urban public toilets that the number of squatting seats in the men's toilets is 400 people, and the number...
