Abstract
The artificial wetland device comprises a sewage treatment part, a water inlet part and a water outlet part, and the sewage treatment part is used for providing physical, chemical and biological water purification environments; the water inlet part is used for inputting sewage into the sewage treatment part; the water outlet part is used for discharging purified water treated by the sewage treatment part; the water inlet part comprises a first water inlet pipe and a second water inlet pipe, the first water inlet pipe is arranged at the starting end of the sewage treatment part and used for continuously conveying horizontal flow sewage, and the second water inlet pipe is arranged to extend towards the water outlet part and used for conveying vertical flow sewage to the sewage treatment part. The constructed wetland device can effectively purify sewage discharge under different conditions, and has universality. The invention also provides a sewage purification method.
Description
technical field [0001] The invention relates to the field of environment, in particular to the field of polluted water purification. Background technique [0002] At present, my country's urban drainage pipe network is not perfect, the problem of mixed connection of pipe networks is common, the efficiency of sewage interception projects is not high, and the direct discharge of sewage into the river causes serious pollution, and the river receives a high pollution load. Among them, the short-term impact of the initial rainwater and overflow pollution on the water quality of the river is particularly prominent due to the serious mixing of rain and sewage in the split pipe network or the small interception multiple of the combined pipe network. [0003] Constructed wetlands are currently the most studied sewage purification technology in China, but there are still problems such as poor denitrification capacity and slow purification treatment speed, especially for large-flow sew...
