Nutrients, especially nitrogen and phosphorus, are accumulating in other places.
Organic pollution: COD, BOD, total suspended solids, nitrogen and phosphorus;
Nitrogen and phosphorus in lakes(by catchment size and type);
Pollution, in particular the buildup of nutrients such as nitrogen and phosphorus in the environment.
As a more stringent measure, nitrogen and phosphorus removal may be needed(tertiary treatment), if the status of the waters in the recipients so requires.
Notably, the drainage waters contain sulphates, chlorides, sodium, and pesticides,as well as nitrogen and phosphorus compounds.
According to the status of recipient waters, the nitrogen and phosphorus removal is recommended for wastewater treatment plants with> 10,000 PE.
For drinking water capture zones under sensitive areas,it also requires compliance with standards for nitrogen and phosphorus.
Two key nutrients, nitrogen and phosphorus, remain vital to sustaining crop production and ensuring food security.
Most municipal WWTPs built in the 1970s and 1980s were not designed to remove nutrients, nitrogen and phosphorus.
Greenhouse-gas emissions, biodiversity loss, nitrogen and phosphorus overuse and ocean acidification have reached alarming levels.
In addition to local pressures on surface waters, there are also transboundary pressures, for example,due to nitrogen and phosphorus.
Common forms of pollution- particularly nutrients(nitrogen and phosphorus)- and diffuse discharges adversely affect the status of surface waters.
Issue: Nitrogen and phosphorus enrichment can result in a chain of undesirable effects, starting with excessive growth of plankton algae, which increases the amount of organic matter settling to the bottom.
Extensive use of irrigation and diffuse pollution from the use of nutrients(nitrogen and phosphorus) in agriculture and from livestock also exert pressure.
The combined use of nitrogen and phosphorus fertilizers on the permanent sowing of wheat was economically justified, because it increases the quality of grain and profit per hectare.
Agriculture leads to problems with high contents of nutrients, such as nitrogen and phosphorus in surface waterand groundwater, coastal water and the marine environment.
In previous and current blogs, we have discussed the problems associated with animal production such as the tendency to overformulate with protein and the downsides to this approach,as well as nitrogen and phosphorus waste that escapes the farm.
For example, there have been cases where nitrogen and phosphorus flow into lakes and ponds from agricultural land, which has led to deterioration of water quality.
Because of the importance of deep sea sediments in biogeochemical cycles, marine bacteriophage must influence the carbon, nitrogen and phosphorus cycles, but the exact influences are currently not understood.
For example, there have been cases where nitrogen and phosphorus have flowed into lakesand ponds from agricultural land, which has led to a deterioration in water quality.
Existing wastewater treatment facilities have limited capacity for dealing with industrial wastewater discharges,particularly biogenic substances, nitrogen and phosphorus, but also casein, which comes from milk processing plants;
The enrichment of water by nutrients such as nitrogen and phosphorus can also lead to eutrophication, which again can have significant environmental effects.
Agriculture is another pressure factor: as a significant water user it has impacts on water quantity and as user of pesticides as well as manure and/or nitrogen and phosphorus fertilizers it has impacts on the quality of surface waters or groundwaters.
Elevated nutrient concentrations,especially nitrogen and phosphorus which are key components of fertilizers, can increase periphyton growth, which can be particularly dangerous in slow-moving streams.
Agriculture is another pressure factor: as a significant water user it has impacts on water quantity, and through the use of pesticides,manure and/or nitrogen and phosphorus fertilizers it has impacts on the quality of surface waters or groundwaters.
Determination of the technological indicators for nitrogen and phosphorus compounds is based greatly on the expert assessment due to the small number of projects using BATand due to the differences in the technologies applied.
The biggest point sources of organic and nutrients loads on SWBs are untreated wastewaters of Kyiv and Chernigiv(Table 8.) and the biggest amount of organic matter, nitrogen and phosphorus are discharged together with wastewaters into the rivers.
Danube countries obtained results on nitrogen and phosphorus emissions via various pathways, their contributions to the total emissions for the Danubeand the share of the countries within the Danube River basin for the period 1998-2000 tons/year; percentage.
Activities focus on the improvement of contaminated watercourses,polluted especially by heavy metals, nitrogen and phosphorus, mainly from agriculture, industry and transportation, and prevention of further eutrophication.
