Malodorous gas will not only emit unpleasant odors, but also cause serious secondary pollution. Some toxic and harmful malodorous polluting gases will have adverse effects on the human respiratory system, digestive system, endocrine system and spirit. High concentrations can also lead to poisoning and even death.
The sources of malodorous pollutants can be divided into two types: natural sources and artificial sources: natural sources specifically refer to malodorous gases produced by the decomposition and deterioration of animals and plants, and artificial sources can be subdivided into industrial production pollution sources and centralized life management There are two sources of facilities.
1. Natural source:
(1) The stench of agriculture and animal husbandry. The stench produced by livestock farms, poultry farms, slaughter plants, and fish processing plants in agriculture and animal husbandry. Such as dung odor, fish odor, rotten & decaying odor, rotten fruit odor, wild vegetable odor, etc. are all produced in the agricultural production and processing.
Â
2. Artificial sources:
(1) Odor from industrial production. The odor generated in industrial production, the main sectors that produce odor are petroleum refineries, food processing, paper industry, rubber industry, alcohol brewing, plastic processing, pharmaceuticals and pesticides, paint production, etc. The malodorous substances produced by these sectors include sulfides, hydrocarbons, aldehydes, ketones, benzenes, teas, amines, tar, pitch steam, ammonia and various organic solvents.
(2) The stench of centralized living treatment facilities. Such as waste incineration plants, landfill plants, sewage treatment plants, sewage pumping stations, hospitals, public toilets and other public facilities, such as sewage odor, medicine odor, disinfectant odor, urine odor, hospital odor, bathroom odor, etc. .
Due to the strong timeliness of the odor emission, the wide range of sources and many uncertain factors, it is difficult for the environmental protection department to trace the source, obtain evidence, enforce the law, and govern. Therefore, there is an urgent need to establish a real-time, efficient and rapid automatic monitoring system for odor. The odor situation is continuously monitored for 24 hours.
Tianjin Zhiyi Times Technology Development Co., Ltd. has developed an integrated online monitoring of odor concentration (OU), ammonia (NH3), hydrogen sulfide (H2S), and total volatile organic compounds (TVOC) for the monitoring of odor pollutants. The equipment, the product quality is high, the price is competitive, and the product performance is stable, which can provide strong data support for the supervision and treatment of malodor.
As people pay more attention to malodorous gas pollution and the establishment and improvement of relevant policies and regulations, it is believed that the monitoring, prevention and treatment of malodorous pollution sources will rise to a new stage.
Saline Injection Machine
Stainless Steel Manual Chicken Saline Injection Machine Saline Injection Machine Price
1. The fully automatic saline brine injection machine can evenly inject the pickling solution prepared with brine and auxiliary materials into the meat, which not only shortens the pickling time, but also makes the pickling agent evenly distributed, greatly improving the taste and yield of meat products.
2. This meat saline injection is easy to clean and has a reasonable structure. The whole machine is made of 304 stainless steel and is clean and hygienic. It is an indispensable equipment in the meat industry.
3. According to different technological requirements, the stepping speed, the stepping distance, the gap between the pressing plate and the injection pressure can be adjusted to inject the pickling liquid evenly and continuously into the meat to achieve the ideal injection effect.
