In water treatment, sewage treatment and other fields, harmful gases produced in the hydrolysis process, such as carbon dioxide, hydrogen sulfide, ammonia, etc.

There are a variety of applications for users to choose. From the gas detector and purity analysis, we have professional products to meet the requirements of complex environment.

There are many places in water + sewage treatment facilities that contain dangerous gases and toxic and explosive chemicals. It is necessary to select different gas detection instruments according to the use environment and implement monitoring.

The sewage treatment plant gathers urban domestic sewage, industrial sewage, runoff sewage and so on. It is collected by urban pipeline and should pass through urban sewage treatment plant. There are a lot of organic matter, virus and bacteria in the sewage. Among them, gas hazards cause great trouble to the inside and surrounding of the plant. The wastewater was collected and fermented to produce hydrogen sulfide (H2S), ammonia (NH3), methane (CH4) and carbon monoxide (CO). The odor that people smell is hydrogen sulfide and ammonia.

Soluction

1. Selection of real time on line monitoring system equipment (gas detector) for ammonia, hydrogen sulfide and methane in the sewage treatment plant.

Since the detection range of ammonia, hydrogen sulfide and methane detectors is 20-30 square meters, it is very good to judge the number of ammonia, hydrogen sulfide and methane concentration detectors in relatively closed environment, such as production workshop. It only needs to divide the average volume of the detection environment by 20-30 square meters.

For outdoor and other open environment, the number of ammonia, hydrogen sulfide and methane concentration detectors used in the sludge treatment plant should be considered from the perspective of safety protection. At this time, gas leakage detectors must be installed at the points easy to leak (pipeline interface, etc.) and the designated safe places for safety detection, In this case, we need to customize the number of ammonia, hydrogen sulfide and methane detectors for specific environment.

2. Matters needing attention in installation of real time online monitoring system for ammonia, hydrogen sulfide and methane in sewage treatment plant.

The real-time gas on-line monitoring system of sewage treatment plant is composed of ammonia, hydrogen sulfide, methane detector and alarm controller host. The gas detector is installed in the operation site, while the alarm control host is installed in the monitoring room and other convenient monitoring environment. For the installation location of ammonia, hydrogen sulfide and methane detectors in sludge treatment plant, the location where ammonia, hydrogen sulfide and methane are easy to leak is mainly selected to install the ammonia detector equipment, and the location where the operating personnel do not affect the normal operation is also selected to install the ammonia, hydrogen sulfide and methane detectors.
