As shown in fig. 6, steps are as follows with method for early warning for detection automatically for the water nutrition of described device:
Water acquisition pumps 2 one end and gos deep under the waters surface such as ocean, lake, river, and water acquisition pump 2 is taken out water sample to be measured by water pipe 13 From the water surface, water sample inlet triplet for water 14 divides for two-way, is connected all the way with settling tank 3;Another way is connected with detection cell 27;
In settling tank 3, water sample enters the pipe with holes 20 being connect with water inlet 1, through the hole on pipe 20 with holes Outflow, flows down, the solenoid valve 2 18 of water outlet 1 is in closed state, funnel bottom solenoid valve at this time along 3 inner wall of settling tank One 17 are in open state, and water sample is flowed out through pipe 20 with holes rinses 3 inner wall of settling tank, is flowed out from solenoid valve 1;It is heavy to complete After dropping the flushing of pond 3, solenoid valve 1 is closed, and water acquisition pump 2 persistently draws water, and settling tank 3 starts water storage, after reaching setting time, adopts Water pump 2 is stopped;Settling tank 3 overflows water and is discharged by overflow conduit 22, prevents the too high equipment that is spilled over to of 3 water level of settling tank from putting down Platform 1, after reaching the predetermined sedimentation time, particulate matter is settled down to 3 bottom of settling tank, and solenoid valve 2 18 is opened, and water sample is by water inlet two 28 flow into backwash filter 4;
The water sample for flowing into backwash filter 4 enters cylinder 26, is flowed out by water outlet 2 29 after the filtering of filter core 25;
25 filtered water sample of filter core is pumped into detection cell 1 by compression pump 5 by three-way magnetic valve 1, and water storage is nutrition Salt detecting instrument 8 cleans, after water storage to water level there is not the detection window of overnutrition salt detecting instrument 8, from three-way magnetic valve 1 Third road is discharged, and nutritive salt detecting instrument 8 starts to detect after water storage success again, and data transmission obtains number with warning module 10 According to beyond normal range (NR) alarm and notifying user;After the completion of one detection cycle, nutritive salt detecting instrument 8 stops acquisition number According to the solenoid valve 2 18 of water outlet 1 is closed, and the 3 electronic impeller 19 in inside of settling tank stirs water body containing deposit, then settles 3 bottom solenoid valve 1 of pond is opened, the sewage discharge in settling tank 3.
Meanwhile compression pump 5 reversely extracts the water sample in detection cell 1, water sample enters filter through three-way magnetic valve 1 Filter core 25 is permeated by 25 interior of filter core, rinses out the impurity screening outside filter core 25, and solenoid valve 2 18 is closed, recoil The solenoid valve 3 27 for washing 4 bottom of filter is opened, and backwashing sewage water is discharged from magnet valve 3 27, and water sample backwash can prevent filter Filter core 25 blocks, and after the completion of back flush, the remaining water of one 6 funnel bottom of detection cell is arranged by one 30 third road of three-way magnetic valve It is empty;
In detection cell 27, water storage first is cleaned for water quality sensor 9, and water storage to water level there was not multi-parameter water quality sensing It after the detection window of device 9, is discharged from the third road of three-way magnetic valve 2 31, again multi-parameter water quality sensor 9 after water storage success Start to detect, data transmission obtains data with warning module 10, beyond normal range (NR) alarm and notifies user;One detection week After the completion of phase, discharge of the water sample from three-way magnetic valve 2 31.
Assessment of Eutrophication Status model is using eutrophication index method, calculation formula in seawater:
E=(CCOD×CDIN×CDIP×106)/4500 (1)
Wherein,
E:Eutrophication index;
CCOD:COD concentration, unit mg/L;
CDIN:Inorganic nitrogen concentration, i.e. nitrite-nitrogen (NO2-N), nitrate-nitrogen (NO3-N), ammonia-nitrogen (NH4-N) are dense The summation of degree, unit are mg/L;
CDIP:Reactive phosphate concentration, unit mg/L.
Work as E<When 1, water body is in non-eutrophic state, and warning module 10 does not send out alarm;
As 1≤E≤3, water body is in lightly eutrophicated, and data transmission sends out the slight rich battalion of yellow with warning module 10 Fosterization alarm;
When 3<When E≤9, water body is in moderate eutrophication, and data transmission sends out orange moderate richness with warning module 10 and seeks Fosterization alarm;
Work as E>When 9, water body is in serious rice-nutrient, and data transmission sends out red serious rice-nutrient with warning module 10 Alarm.
Lake eutrophication evaluation uses mathematic(al) mode determining method, when [chemical oxygen consumption (COC) (mg/L) × Phos (p pm) × inorganic nitrogen (ppm)/1500] >=l when water body reach eutrophic state, data transmission sends out red richness with warning module 10 Nutrient laden alarm.
The generation of red tide or wawter bloom by the factors such as nutritive salt, illumination, temperature, salinity, dissolved oxygen, turbidity synthesis shadow It rings, according to Zou Jingzhong (1983), the research of water logging et al. (1994) takes pH>8.22 or saturation dissolved oxygen>110% or leaf Green element>10mg/L is red tide threshold value, and data transmission is compared analysis with warning module 10, and monitoring data reach arbitrary wherein one When a threshold value, the blue early warning of red tide or wawter bloom is sent out.
