Embodiment Construction

[0017] The water biological compound nitrogen reduction technology of the present invention uses the aquatic biological food chain as a carrier to remove organic matter and inorganic salts such as nitrogen from the reservoir to reduce the nitrogen content of the reservoir water. The establishment of the aquatic biological food chain includes:

[0018] A Calculate the amount of active agent potassium dihydrogen phosphate that needs to be added according to the water body, dissolve the food additive grade potassium dihydrogen phosphate in water, and sprinkle it evenly in the water body, so that the phosphorus-nitrogen ratio reaches 8:1, and establish a normal material cycle and the water quality environment to maintain the normal productivity of the water body;

[0019] Calculation of the amount of active agent potassium dihydrogen phosphate, according to the water chemical analysis data, total phosphorus (TP), PO43- and total nitrogen (TN), nitrate nitrogen (NO3—N) and nitrite n...

Abstract

The invention discloses a nitrogen reduction technology through compounding of biological organisms in a water body. An aquatic organism food chain is taken as a carrier, organic matters such as nitrogen and inorganic salt are removed out of a reservoir, and the content of nitrogen in the reservoir is reduced. According to the technology, the content of nitrogen in the reservoir can be reduced, and the technology has high stability and reliability, is flexible to control and low in cost and has good economic benefits.

Description

technical field [0001] The invention relates to a water body biological compound nitrogen reduction technology. Background technique [0002] Wangwu Reservoir is located in the middle and upper reaches of the Yellow River in Longkou City, Shandong Province, in Shiliang Town and Qijia Town. With a basin area of ​​320km2, it is a large (two) type reservoir integrating flood control, irrigation, urban and rural water supply, and fish farming, with a total storage capacity of 121 million m3 and a total area of ​​10.4km2. It is the only large reservoir in Longkou City. Responsible for the urban water supply of Longkou City, it supplies about 30 million m3 of drinking water, industrial and agricultural water, and ecological water to urban and rural areas every year, and is the main water source of Longkou City. The water quality is required to meet Class III surface water. Due to the extensive use of chemical fertilizers in the rural planting industry within the reservoir basin...
