Overview
The second-generation rapid detection technology for microbial activity (industrial park wastewater poisoning early warning rapid detector) achieves quantitative analysis of microorganisms by analyzing the concentration of ATP (adenosine triphosphate) in microbial cells. In the field of sewage treatment, this technology can establish direct observation methods for the activity and status of microorganisms in sludge and obtain real-time quantitative data; Complementing MLSS, microscopy, and other methods, it helps sewage treatment plants accurately understand the status of microorganisms, thereby improving the stability of process control.
Product Details
Application Scenario:
Wastewater treatment: toxicity warning for incoming water, detection of active microorganisms, process optimization;
The sewage treatment plants in industrial parks are often affected by the biochemical processes of the plants due to the production enterprises in the park illegally discharging, changing processes, and altering raw materials. The heavy metals, high ammonia nitrogen, high phosphorus, high salt content, toxic substances (including fluorides), and difficult to degrade components contained in the discharged sewage will have a certain impact on the activated sludge, affecting the removal efficiency of COD and ammonia nitrogen. In severe cases, the sludge may even need to be replaced.
Working Principle:
ATP (adenosine triphosphate) is the direct source of energy required for all life activities of microbial cells. The concentration of ATP reflects the speed of microbial metabolism and can therefore also be used to characterize the activity of sludge.Industrial park sewage poisoning warning rapid detectorThe application of wastewater toxicity warning in industrial parks is to quantitatively analyze the ATP concentration in the active microbial cells of sludge under different inflow conditions to determine whether the inflow is toxic to microorganisms.
Product advantages：
1.Chemical Industry Park Sewage Poisoning Warning Quick DetectorbaseAt ATThe P (adenosine triphosphate) luciferase method calculates the ATP concentration in a sample by measuring the brightness produced when ATP and luciferase are mixed;
2During the operation, ATP concentration in microbial cells is released and accurately measured through steps such as breaking the wall to remove interference;
3.Industrial park sewage poisoning warning rapid detectorThe sensitivity can reach 0.1pg/mLATP (100 ME/ml, 100 microbial equivalents per milliliter)
Principles of toxicity analysis:
1. Mix the incoming water and activated sludge in a certain proportion, simulate the conditions in the reaction tank, and mix with or without aeration for 1 hour
2.Industrial park sewage poisoning warning rapid detectorTake samples for ATP analysis and compare the analysis results
Bottle analysis is the most commonly used method for toxicity testing of incoming water. Bottle analysis can simulate the real mixing state of sewage and activated sludge under process conditions, accurately evaluating the comprehensive toxicity of sewage. If the bottle analysis results show that ATP loss exceeds 30%, it can be determined that the toxicity of sewage has exceeded the tolerance of sludge.
Case sharing:
（one）Toxicity analysis of unknown incoming water in an industrial park in Shanxi Province
Operation Challenge：Chemical Hospital Park,There are multiple sources of incoming water, and there are cases of illegal dischargeworkmanshipAffected by the toxicity of incoming water, undertake some external sewage treatment tasks.
Usage strategy: Conduct incoming water toxicity analysis on each sewage stream separately, evaluate the incoming water toxicity, and design appropriate mixing methods to reduce overall toxicity.
（two）Toxicity analysis of unknown components
A certain factory is considering using a new raw material in its production process, but at the same time, it is concerned that the components in the new raw material may have an impact on downstream sewage treatment processes. Therefore, it has decided to conduct toxicity testing on the sludge from the aerobic process section first. During the testing process, new raw materials were added to the sludge according to different concentration gradients (100-1000mg/L), and the changes in sludge activity were tracked for 24 hours. The experimental results showed that the new substance would temporarily inhibit the activity of sludge in a short period of time, and the degree of inhibition would increase with the increase of concentration. However, the inhibition of sludge activity by the substance is reversible. After 24 hours, the activity of sludge recovered by 90%, proving that the sludge has sufficient self-regulation ability to resist toxicity.
（three）Daily monitoring of reaction tank
When using ATP for daily toxicity water warning, continuous monitoring can be used to detect the time point when the ATP concentration in sludge drops sharply. If the daily ATP concentration fluctuation is greater than 25% of the daily average value, it can be judged that the incoming water has obvious toxicity. Water samples can be taken for static unknown incoming water toxicity analysis (such as Case 1) for verification, and corresponding protective measures can be taken to protect the process. At the same time, when monitoring ATP on a daily basis, a system can be set based on experience to allow low ATP values, leaving a certain buffer space during operation to improve the system's shock resistance. For example, northern sewage treatment plants can prepare in advance when the autumn and winter seasons change.
