Description

A sampling device for sewage detection

technical field

The utility model relates to the field of water source sampling equipment, in particular to a sampling device for sewage detection.

Background technique

Living sewage is mainly a variety of detergents and sewage, garbage, and feces used in urban life. Most of them are non-toxic inorganic salts. Domestic sewage contains nitrogen, phosphorus, and sulfur, and many pathogenic bacteria. Domestic sewage is also a low-temperature heat source and a source of methane generation. It is also one of the main pollution sources of water bodies. Mainly feces and washing sewage, sampling refers to the process of taking individuals or samples from the population, that is, the process of testing or observing the population. There are two types of random sampling and non-random sampling. The former refers to a sampling method that draws samples from the population in accordance with the principle of randomization, without any subjectivity, including simple random sampling, systematic sampling, cluster sampling and stratified sampling. The latter is a method of extracting samples based on the researcher's point of view, experience or related knowledge, with obvious subjective color.

The existing sampling method for sewage treatment only uses a container to collect sewage manually by sewage inspectors during sampling. Due to the phenomenon of stratification of sewage when it is left standing, only the sewage on the surface of the sewage pool can be obtained in this way, and sewage sampling is generally correct. The surface water is sampled, and it is impossible to go deep into the water to sample water at different depths, which has the disadvantages of difficult sewage extraction, poor detection stability, and low accuracy.

Therefore, it is necessary to provide a sampling device for sewage detection to solve the above technical problems.
