Foreword

To implement the "People's Republic of China Environmental Protection Law", "People's Republic of China Water Pollution Prevention Law," protecting the environment, safeguarding human health Kang, standardized quality vocabulary, the development of this standard. This standard is the "quality first and second portions Vocabulary" (GB 6816-86) and "Water quality - Vocabulary - Part III Part VII "(GB 11915-89) amendments. This standard were first issued in 1986 and 1989, the original drafter of China National Environmental Monitoring Center, this is the first revision. The revised standard is divided into seven parts. 1. Water quality - Vocabulary section; 2. The second part of the vocabulary of water quality; 3. Water quality - Vocabulary - Part III; 4. Water quality - Vocabulary - Part IV; 5. Water Vocabulary Part V; 6. Water quality - Vocabulary - Part VI; 7. Water quality - Vocabulary - Part VII. Words defined in this section is designed for term water quality characteristics provided mainly include "Water quality - Vocabulary - Part V," and the term Define (including the corresponding English terminology), it Terminology published at home and abroad may be the same, but when applied to different areas, they The definition may be different. This section vocabulary equivalent to international standards "Water quality - Vocabulary - Part 5" (ISO 6107.5-2004), with English terms ISO 6107.5-2004 consistent. Some entries may appear twice, but the interpretation is different for different situations to explain. From the date of implementation of this standard, the former State Environmental Protection Agency October 10, 1986 approved by the State Environmental Protection issued the standard "water Vocabulary quality first and second portions "(GB 6816-86) and the former State Environmental Protection Agency December 25, 1989 approved, release Environmental Standards "Water quality - Vocabulary - Part III - Part VII" (GB 11915-89) abolished. This standard is developed by the Ministry of Environmental Protection Science, Technology organization. This standard is mainly drafted by. China National Environmental Monitoring Center, the Liaoning Provincial Environmental Monitoring Experiment Center. This standard MEP November 5, 2010 for approval. This standard since March 1, 2011 implementation. The standard explanation by the Ministry of Environmental Protection. Water Vocabulary Part V

Some PAHs, including benzo [a] pyrene, indeno [1,2,3-cd] pyrene and benzo [b] fluoranthene, has been shown to be carcinogenic in experimental animals, people may Body cancer. 2.7 zooplankton zooplankton Plankton fauna class. 2.8 plankton plankton Rafting or biological suspended in water. Mainly by small plant or animal composition, including poor exercise capacity of the larger species. 2.9 Phytoplankton phytoplankton Plankton flora category. 2.10 humic acid humic acids In alkaline solution dissolved in the acid solution and precipitated humus component. 2.11 humus humic substances An amorphous complex macromolecular polymeric organic material. Animals and plants are in the soil and sediment humification product, make surface water presents Yellowish brown features. 2.12 fulvic acid fulvic acids Acid, alkali solution can dissolve humus component. 2.13 senses organoleptic Through the senses to describe the characteristics of the water, such as color, taste, smell and appearance. 2.14 filterability filterability; filterability filtrability In the sludge treatment process, showing the difficulty of separating the solid-liquid phase by filtration. 2.15 combined sewer system combined sewerage system Wastewater and surface runoff water systems share the same set of drains and sewers. 2.16 riverbank storage bankside storage Raw water storage reservoir on the shore. 2.17 environmental adaptability acclimatization Biological populations to natural changes in the environment or long-term changes (such as industrial wastewater and domestic sewage discharge duration) applied to human adaptation process. NOTE. In some countries, acclimation and acclimatization as synonyms. 2.18 carps cyprinid Belonging carp fish, sometimes used as a biological indicator of water quality. For example, roach, rudd, carp. 2.19 fluidized bed fluidized bed In the upward flow, under the action of air or a combination of both, to form a free small particles suspended in the filter bed. 2.20 membrane filtration membrane filtration Through a certain pore size of the membrane filtration to remove particulate matter and microbial or enriched (excluding free virus) technique from the fluid. NOTE. This technique is applied to a variety of physical - chemical and microbiology, for example. liquids and gases "sterile" and separating the microorganisms from the free virus Virus isolation test for the quantitative evaluation. 2.21 Reversal turnover Natural forces (normally by the wind) caused the rapid destruction of freshwater body of water (such as lakes or reservoirs) layering effect. 2.22 plate count plate count; colony counting colony count Estimates of the number of a certain volume of water living microorganisms (including bacteria, yeasts and molds). Under specified conditions, the number by a The number of colonies in a given medium or the surface is obtained. 2.23 destratification destratification With the forces of nature or artificial means, so that the surface water and the lower water lake or reservoir mixing. 2.24 hypoxia anoxic The dissolved oxygen concentration is too low leads to the use of microorganisms priority nitrogen, sulfur or carbon oxidation state as a state of the electron acceptor. 2.25 (sludge) heat treatment heat treatment (of sludge); heat regulating thermal conditioning It is adjusted by heating the sludge (often required pressure), so that the sludge is dewatered in a static or dynamic dewatering easier. 2.26 dissolved organic carbon dissolved organic carbon, DOC That is not part of the organic carbon removal from the water with a specific filtration methods.
