Safety inspection well system of septic tank

Abstract

The invention discloses a safety inspection well system of a septic tank. The safety inspection well system comprises an inspection well, a well frame and a well lid and further comprises a gas concentration sensor, a gas pressure sensor and an exhaust valve, wherein the gas concentration sensor, the gas pressure sensor and the exhaust valve can be arranged on the well lid, and a gas inlet of the exhaust valve directly faces a ventilation hole formed in the well lid. The working principle of the safety inspection well system is as follows: the gas concentration sensor and the gas pressure sensor are used for sensing concentration or pressure of gas such as biogas and the like in the septic tank, after the concentration or the pressure reaches a set value, the exhaust valve is controlled to be opened automatically by the aid of a sensing signal triggering controller, the septic tank and the atmosphere are communicated for exhaust, exhaust is performed automatically by the aid of the exhaust valve, the pressure or the concentration of the gas can be reduced, the pressure or the concentration of harmful gas in the septic tank is automatically kept within a safety value, public surrounding environment safety and public personal safety can be guaranteed, and the system is convenient to operate and maintain and high in practicability.

Description

technical field [0001] The invention belongs to the field of municipal environmental protection infrastructure, and in particular relates to a septic tank safety inspection well system. Background technique [0002] Among the existing municipal environmental protection infrastructure, septic tanks are an essential infrastructure facility, with a huge number and wide application areas, and are extremely important municipal environmental protection facilities. Nowadays, in many cities in our country, septic tank has become one of the basic measures of environmental protection. Septic tank is a basic sludge treatment facility and also a pretreatment facility for urban domestic sewage. Its functions are as follows: [0003] 1. Ensure the environmental sanitation of the living community and avoid the spread of domestic sewage and pollutants in the living environment. [0004] 2. In the working environment of anaerobic corrosion in septic tanks, kill mosquito eggs. [0005] 3. ...

AI Technical Summary

Problems solved by technology

Biogas is a mixed gas, which contains a large amount of flammable gases such as methane, ammonia, nitrogen and carbon dioxide, and contains toxic gases such as carbon monoxide and hydrogen sulfide. When the gas concentration reaches the explosion limit, it will explode when it encounters open flame or other frictional energy. At the same time, due to the presence of a large amount of toxic gas in the septic tank, there are tragic cases of poisoning and death among the personnel who clean up the septic tank

Therefore, septic tanks are extremely dangerous
