Part IV Water Glossary
1 Scope
This standard specifies the terms provided specifically for the characteristics of water quality.
2 Terminology
Between 2.1 intertidal intertidal zone
At the average high tide and low tide water level within the average range of the coastal zone.
With 2.2 tidal subtidal zone
Lower than the average low tide level of the coastal zone.
2.3 crushing comminution
Coarse solids in the waste water, by mechanical crushing or grinding into small particles, to facilitate further processing.
2.4 coagulation coagulation
Coagulant, the colloidal dispersion destabilization and coagulation (chemical coagulation and flocculation) process.
2.5 interstitial water interstitial water
The gap between the solid particle (hole) memory of water left.
2.6 biodegradability biodegradability
Biodegradable organics performance.
2.7 ion balance ionic balance
In aqueous solution, the total of all cations and anions of ionic charge number and the molar concentration of algebra and should be zero. If the actual analysis
Results calculated algebraic and not equal to zero, then the measurement item incomplete (some ions not determined), or there is an error in the analysis.
2.8 pycnocline pycnocline
Water maximum aqueous layer density gradient layering.

Low, long sludge age (about 50 d), the remaining sludge is generally stable, but slow growth of microorganisms in the system more stable, can be oxidized to remove it
His way is difficult to degrade substances.
2.18 mobile water treatment equipment package plant
Typically used to handle small amounts of water and sewage prefabricated compact device.
