The wastewater generated in the scenic area mainly includes catering, black water (fecal sewage) and gray water, shower wastewater and some recreational water. Catering wastewater in scenic spots contains a large amount of grease and high COD content, which can easily cause blockage of the sewage pipe network; toilet sewage in scenic spots has a large proportion of black water and a high content of ammonia nitrogen pollutants, which can easily cause odor; conventional domestic sewage has a large proportion of gray water, which causes various pollution substance concentration is relatively low. At the same time, because wastewater is dispersed in scenic spots, and its water volume is also related to seasons and tourist peak hours, the water volume and pollutant types fluctuate greatly.

At present, there are various treatment models for sewage in scenic spots: there are sewage treatment plants nearby for centralized network treatment; small scenic spots are treated decentrally, and tourist towns are treated centrally.

The treatment processes for wastewater in scenic spots mainly include the following three categories:

(1) Ordinary domestic wastewater: domestic sewage → septic tank → collection tank → regulating tank → integrated sewage treatment equipment → discharge according to standards;

(2) Grease-containing catering wastewater: oily wastewater → grease trap → septic tank → regulating tank → integrated sewage treatment equipment → discharge in compliance with standards;

(3) Centralized wastewater treatment: Scenic area wastewater → grille → grit adjustment tank → MBR system treatment tank → disinfection tank → discharge according to standards;

The existing treatment processes for wastewater from scenic spots mainly have the following shortcomings:

(1) The existing process only treats single-state pollutants and does not realize the joint treatment of "three wastes".

(2) The treatment object is single, only the conventional wastewater produced in the scenic spot, and the leachate water generated by the solid waste residue with a large water content cannot be treated in a timely manner.

(3) The equipment costs high, covers a large area, and cannot be flexible according to actual site requirements.

(4) The process flow is complex and the operating cost is high.

(5) The applicability of sewage treatment technology is low. Scenic spots are affected by terrain, season and passenger flow, and the total amount and characteristics of sewage change greatly. The existing technology has problems such as weak impact resistance and low temperature resistance.

(6) The process treatment is imperfect, and the solid waste and sludge generated during the process are not effectively treated and utilized.
