Problems solved by technology

[0008] Aiming at the cumbersome and heavy workload problems of classification, identification, counting and statistics of micro-animal communities in the prior art, the present invention provides a method for monitoring the effect of biofilm water treatment based on the speed analysis of micro-animals; the inventors found that : In biofilm sewage treatment, when the environment is good, the movement speed of micro-animals is normal, and the sewage treatment effect is good; when the ecological system environment is bad, the movement of micro-animals is affected, the speed slows down, the sewage treatment effect becomes worse, and the movement speed of micro-animals It is a comprehensive reflection of the water treatment environment

Embodiment 1

[0056] A method for monitoring the effect of biofilm water treatment based on micro-animal speed analysis in this embodiment, the specific process is:

[0057] 1) Collection of K3-type suspended filler biofilm micro-fauna: In the reactor of K3-type filler biological contact oxidation method for treating urban sewage, scrape a small amount of mature biofilm from the filler, dilute with distilled water to make a mixed solution, and use a small amount of Pipette 25uL of the mixture onto a glass slide and cover with a coverslip.

[0058] 2) Microscopic observation of common micro-animal movement and morphological changes, tracking and shooting the movement process of the top 20 micro-animals ranked by dominance and recording them into videos. Use image-pro plus software to draw the motion track of this video, analyze the motion mode and calculate the average motion speed of each micro animal.

[0059] 3) Establish the correlation function between the movement speed and the remova...

Embodiment 2

[0070] A method for monitoring the effect of biofilm water treatment based on micro-animal speed analysis in this embodiment, the specific process is:

Abstract

The invention discloses a microfauna velocity analysis-based biofilm process water treatment effect monitoring method, and belongs to the technical field of sewage treatment. A method for monitoring the pollutant removal effect through observing the movement mode of microfauna indicated by behaviors in a sewage biofilm process system and analyzing the movement velocity is built by judging the complexity and the triviality of water quality indexes of sewage for time consumption of analysis through chemical indexes at present and community characteristics of the microfauna. Specifically, the movement mode of the microfauna indicated in a biofilm is observed, the movement velocity of the microfauna is calculated and the sewage treatment effect is analyzed and monitored through dynamic microscopic video shooting and static picture analysis methods; and an more effective method is provided for water quality monitoring of sewage treatment and process operation condition judgment and management.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and more specifically relates to a method for monitoring water treatment effect of a biofilm method based on micro-animal speed analysis. Background technique [0002] In sewage treatment, the water quality chemical analysis can be used to judge the quality of the sewage, but the chemical analysis is not only time-consuming, but also the analysis process is cumbersome. Therefore, usually by analyzing some macro indicators (MLSS, MLVSS, SV, SVI) to monitor whether the biological treatment system (activated sludge method, biofilm method) is mature or not, normal or abnormal, and to monitor the effect of sewage treatment. However, macro indicators are often indirect, lagging, and less accurate. [0003] The sewage biological treatment system is a complex system composed of microscopic ecosystems and their organic and inorganic substances. The micro-animals (protozoa, metazoa) are at a hig...
