Rapid testing instrument for basic water quality items in five types of surface water

The synopsis of project
The ERUN-SP series rapid testing instrument for basic water quality items in five types of surface water developed and produced by Erun Group is suitable for quick testing of on-site water quality of rivers, lakes, canals, channels, reservoirs and other surface waters. The multi parameter rapid testing instrument for Class I to V surface water can test the concentration values of basic water quality parameters in GB3838 surface water environmental quality standard, including water temperature, pH value, dissolved oxygen, COD, BOD, ammonia nitrogen, total phosphorus, total nitrogen, heavy metals, inorganic salts, petroleum, fecal coliform bacteria, etc. The portable five types of water quality basic item analyzer can be used for centralized surface water sources, habitats of rare aquatic organisms, spawning grounds/wintering grounds for fish and shrimp, aquaculture areas and other fishery water bodies, as well as swimming areas, agricultural water areas and general landscape requirements water bodies, to determine whether it is a Class I, II water body, or Class III, IV, and V water body.
The contents of project

1、Five types of surface water functional classification:

(1)Class Ⅰ

Mainly suitable for source water and national nature reserves.。

(2)Class 

Mainly suitable for centralized surface water source protection areas, habitats of rare aquatic organisms, spawning grounds for fish and shrimp, and feeding grounds for juvenile and juvenile fish, etc。

(3)Class 

Mainly suitable for centralized drinking water surface water source secondary protection areas, fish and shrimp wintering grounds, migration channels, aquaculture areas and other fishery water bodies and swimming areas。

(4)Class 

Mainly suitable for general industrial water use areas and entertainment water use areas that are not directly in contact with the human body。

(5)Class 

Mainly suitable for agricultural water use areas and water bodies with general landscape requirements。
