Abstract

The invention relates to a high-efficiency artificial wetland sewage treatment system, which comprises a bar screen, a water-collecting sedimentation tank, an aeration tank and an artificial wetland, wherein the bar screen is positioned in front of the water-collecting sedimentation tank, the yield water of the water-collecting sedimentation tank is pumped into the aeration tank by a sewage pump, a plurality of parallel horizontal traverse baffles are arranged in the artificial wetland and divide the artificial wetland into a plurality of parallel water flow passages which are communicated with each other in turn, and the bottoms of the water flow passages are distributed with a plurality of groups of aerators at intervals. The base material of the artificial wetland comprises sand soil mixture, crushed stone, zeolite, limestone, coal slag, steel slag, blast furnace slag, crushed stone, porcelain granules, melon seed piece and pebble and can be cultivated with mussels, and the water outlet end of the artificial wetland is provided with a water storage tank. The high-efficiency artificial wetland sewage treatment system has a simple structure, and can effectively improve the processing effect of the artificial wetland and the purification degree of the yield water of the artificial wetland.

Description

technical field [0001] The invention relates to a sewage treatment system, in particular to a sewage treatment system based on artificial wetlands, belonging to the field of environmental protection. Background technique [0002] Since 1804, the British first used sedimentation and filtration technology as a centralized water treatment plant. In 1884, the Americans invented the coagulation, sedimentation, filtration, and chlorine disinfection technology, which has been used for 120 years. There are new discoveries and improvements in treatment, but the treatment process of domestic water basically remains the same, essentially no update and breakthrough. However, the water source to be treated has undergone great changes: the water source a hundred years ago was not polluted due to the underdevelopment of industry and agriculture. Over the past few decades, the development of modern industry, especially the sudden and rapid development of the chemical industry, the discharg...
