Four, landscape water body monitoring in campus arranges, and implementation step is as follows:
1. on bank and main body waters gauge is set, carries out the campus landscape water body water quantity monitoring in wet season and low water season;
2. carry out campus water quality of landscape water monitoring, comprising: the monitoring point is set, determines sampling point, the method for sampling, sample frequency, determine monitoring index, monitoring method, judgement criteria;
The monitoring point is artificial swamp water-in monitoring point 9, artificial wetland effluent mouth monitoring point 10, monitoring point, A lake 11, monitoring point, B lake 12, if the larger needs of landscape water body carry out the water body subregion, then at artificial swamp entrance and exit 1 monitoring point is set respectively, shoal in landscape water body both sides conveyance canal and shallow water stagnant area arranges 2 monitoring points, and 2 monitoring points are set in the main body waters; Sampling point is laid in each depth of water 0.5m place, monitoring point, and in the sampling of 1/2 depth of water place, sampling point was laid in the subglacial depth of water 0.5m place when water body was freeze-up during depth of water deficiency 1m; The method of sampling (SL219-98) is carried out by " monitoring water environment standard "; Sample frequency: one hydrological year of physical and chemical index six times (low water season, wet season, the period when a river is at its normal level each secondary), Biological indicators one hydrological years three times (low water season, wet season and the period when a river is at its normal level are respectively once), do not monitor 3 months winters, suitably increase the monitoring frequency 3 months summers, should strengthen monitoring during for the monitoring project that can not reach water quality requirement or generation pollution incident, normal until quality recovery; Monitoring index is water temperature, pH, dissolved oxygen, chemical oxygen demand (COD), five-day BOD, ammonia nitrogen, total phosphorus, total nitrogen, excrement colibacillus group, total coli group, chlorophyll a; Monitoring method by " water environment quality standard " (GB3838-2002) and " monitoring water environment standard " (SL219-98) method execution of requirements; Judgement criteria adopts " urban sewage reutilization water for scenic environment use water quality " (GB/T 18921-2002) ornamental water for scenic environment use lake class water quality standard.
Monitor tetrameric comprehensive action by campus view supply and configuration, the campus landscape water body recycle system, ecological treatment system and campus landscape water body, make the water yield of landscape water body reach planning requirement, water quality reaches " urban sewage reutilization water for scenic environment use water quality " (GB/T 18921-2002) ornamental water for scenic environment use lake class water quality standard substantially, and its leading indicator is:
BOD5≤6mg/L; Total phosphorus (in P)≤0.5mg/L; Total nitrogen≤15mg/L; Ammonia nitrogen (in N)≤5mg/L; Dissolved oxygen 〉=1.5mg/L; Excrement colibacillus group≤10000/L; PH value: 6-9.
Simultaneously do not have a floating matter apparent, noly beastlyly smell and distinguish the flavor of.
