Pollution Source Detection
Portable detector solution for gas detection in septic tanks
The septic tank is a device for processing feces and filtering. The principle is that the solidified material is decomposed at the bottom of the pool, and the hydrated objects in the upper layer enter the pipeline and flow away, preventing the pipeline from clogging and providing solidified objects (feces and other garbage)with enough time to hydrolyze.
In recent years, news about the explosion of septic tanks has occurred frequently, and the reason for the explosion of septic tanks is nothing more than the production of toxic and harmful gases such as biogas, carbon dioxide, and hydrogen sulfide from the sludge deposited in the septic tanks. In an enclosed area with no air circulation, flammable gases such as methane or biogas may cause fire or even explosion if sparks are accidentally generated by external power.
In order to achieve the purpose of safety forecasting, there are two methods are popular now, one is a portable gas detector, and the other is a networked gas detector. Flammable gas alarms and toxic gas detectors use gas sensors independently developed by Winsen Technology, which have high detection accuracy and selectivity, large measurement range, low maintenance, good anti-interference to chemical poisons, suitable for gas monitoring in septic tanks.
Supporting solution for pollution source detection:
Portable solution for biogas sensor
The portable gas detector can use the ZE03 H2S sensor module of Winsen Technology, adopt the non-split infrared absorption principle and the electrochemical principle to measure the gas concentration of CH4 and CO2 generated in the biogas production process, and at the same time,analyzing the pH of biogas slurry with an external pH probe, which is easy and convenient to operate.
Ammonia sensor creates smart public toilet
The intelligentization of urban public facilities has become an important symbol of the construction of "smart cities". As a modern urban public place, public toilets have clean surrounding environment and fresh air in the toilets, which are an important civilization symbol of modern urban construction. It directly affects people's perception of the city.
Therefore, in order to comprehensively improve the management level of public toilets, establish a long-term management, build a modern new city and create intelligent public toilets in a "smart city"; realize intelligent remote management of public toilet flow monitoring, odor detection, toilet flow detection, automatic deodorization, etc., adopt the latest Internet of Things, cloud computing, etc. It realizes the perfect integration of sanitation public toilet management and intelligent technology. "Smart public toilets" can not only eliminate the unpleasant odor, but also provide a scientific and reasonable management method for the environmental sanitation of public toilets, making the city's sanitation public toilet management more efficient, intelligent and orderly.
