Abstract:
The hot spot of monitoring and evaluation of black and odorous water in rural area was investigated. A method suitable for black and odorous water evaluation in rural area was established by sampling and analyzing the black and odorous water in rural area of Henan Province. The goodness of fit between the sensory and monitoring factors evaluation result and the result evaluated by urban black and odorous water classification standard in descending order was as follows: sensory index and NH3-N (88.8%)> sensory index and ORP (83.8%)> sensory index and DO (70.0%)> sensory index alone (65.0%), and NH3-N (the best evaluation factor) was closely related to the formation of black and odorous water. The sensory index and NH3-N evaluation method is economical, rapid and efficient, which is suitable for rural black and odorous water evaluation, and has great significance for the identification and treatment of black and odorous water in rural area of China.
