Problems solved by technology

The disadvantage is that the removal effect on TSS is poor, and it is easy to clog
[0006] At present, the popularization and application of domestic constructed wetland technology is mainly a wetland system with a single flow type, or a combination of subsurface flow and surface flow. There is no precedent for the combination of vertical flow system and horizontal flow system, and the simulation research is limited to plane There is no systematic and in-depth understanding and report on the combination of wetlands with different flow patterns.

Embodiment Construction

[0026] Figure 1- image 3 As shown, domestic sewage 1 from residential houses first enters the septic tank 2 for fermentation and decomposition, and then overflows into the sedimentation tank 3 to remove settleable solids through sedimentation, and the surface runoff 4 in the rainy season is first collected in the sedimentation tank 3 for processing Settlement storage, the sewage in the sedimentation tank is lifted and pressurized by the sewage pump room 5 into the composite flow constructed wetland system 7. The inflow is through the perforated cloth water pipe 6 in the upper layer of the wetland to achieve uniform water distribution. The perforated pipe is covered with coarse sand or coarse sand. Gravel prevents the emission of odor without affecting the exchange with the atmosphere. The wastewater enters the vertical flow unit 8 in the upper layer of the system first, and the large amount of oxygen that enters the vertical flow unit through suction makes it possible to effective...

Abstract

This invention relates to a complex flow artificial marsh composed of a vertical flow artificial marsh unit at the top and a level flow gravel bed at the bottom to become an integral structure, which is a solid sewage zoology process system, the level flow gravel bed is under the vertical flow marsh unit to reduce occupied areas with exclusive nitrogen-removing effect, in which, TSS, BOD and TN in the sewage are removed effectively and processed water can be collected by collecting wells and used in pouring greenbelt in local areas, besides, rain flows can be stored in underground deposition tanks and processed and re-used by the complex flow artificial marsh to realize situ processing life sewage and rain flows.

Description

Technical field [0001] The invention relates to sewage ecological treatment technology, in particular to a composite flow constructed wetland for sewage treatment and an application system thereof. Background technique [0002] Constructed wetland is a sewage treatment technology developed at the end of the 1970s. It has distinctive characteristics and advantages. It is quickly accepted all over the world and is being used more and more widely. Constructed wetland is a sewage treatment system that is artificially designed to realize the ecological process of natural wetland. It makes full use of wetland plants, soil and microorganisms to remove pollutants in sewage. Like other natural treatment systems, wetland treatment systems can bring extra The benefit of this is a system with low investment and operating costs, convenient maintenance and management, but with a large area. The use of constructed wetlands to treat sewage can preserve and build wetlands with high environmental ...
