Integrated Constructed Wetland Sewage Treatment System

Abstract

An integrated artificial wetland sewage treatment system relates to the field of water treatment technology and solves the technical problem of improving sewage treatment efficiency. The system includes a constructed wetland bed, an anaerobic purification tank, and a lifting pump; a water distributor is laid flat above the artificial wetland bed, and a water collector is laid flat at the bottom; a three-phase separation is fixed inside the anaerobic purification tank. The three-phase separator separates the chamber of the anaerobic purification tank into an upper and lower chamber. The upper chamber is fixed with a water outlet weir and a slag baffle surrounding the water outlet weir. The lower chamber is equipped with a sewage inlet. , mud discharge port; the water inlet of the lift pump is connected to the water outlet of the water outlet weir through the pipe fitting, and the pump water port of the lift pump is connected to the water distributor. The system provided by the invention is suitable for sewage treatment.

Description

technical field [0001] The invention relates to water treatment technology, in particular to the technology of an integrated constructed wetland sewage treatment system. Background technique [0002] As a new sewage treatment process, constructed wetlands emerged in Germany, the United States, Denmark and other countries in the 1970s. In our country, due to the large number of small and medium-sized towns, dense population, limited capital and technology, it is very difficult to develop large-scale sewage treatment plants. Therefore, the construction and operation costs are low, the maintenance is simple, and the effect of artificial wetland technology has broad application prospects in our country. . [0003] In the current artificial wetland sewage treatment technology, the removal of pollutants in the sewage mainly depends on the main body of the wetland, and the sewage treatment efficiency is often not high. The slag is removed from the grid, and the concentration of p...

AI Technical Summary

Problems solved by technology

[0003] In the current artificial wetland sewage treatment technology, the removal of pollutants in the sewage mainly depends on the main body of the wetland, and the sewage treatment efficiency is often not high. Screen slag removal, wetland influent pollutant concentration is too high

Moreover, the current constructed wetlands generally require more land than the amount of treated water. The reason for this is that many constructed wetlands have low hydraulic loads, that is, the amount of sewage treated by wetlands per unit area is low.

Moreover, the existing artificial wetlands are often prone to blockage during operation. The reasons for the blockage are that the wetland influent water quality is difficult to control the concentration of suspended solids is too high, the control of the treated water volume is unstable, the water distribution is uneven, and the wetland main filling material has poor water seepage effect.
