test example 1
[0064] The test site is Jiangxia, Wuhan, with a breeding water surface of 2 mu and a water depth of 1.5 meters. Before application, the algae phase of the water body is mainly blue-green algae, and the water body is aging, with a transparency of only 15 cm. On June 18, 2008, the microbial agent was used, 8KG was used per mu, diluted with 100 times of clear water, and evenly sprinkled in the pond. After 7 days, the transparency increased to 35cm; dissolved oxygen increased from 772mg / L to 1299mg / L; total N, The total P content and permanganate decreased by 30.2%, 28.1% and 17.2%, respectively, and the number of cyanobacteria increased from 53000×10 3 pcs / L down to 9900×10 3 / L, the water body has been significantly improved.
test example 2
[0066] The test site is Makou, Hunan, with a breeding water surface of 80 mu and a water depth of 1.5-2 meters. Before application, the algal phase of the water body is mainly cyanobacteria, and the number of cyanobacteria is 27700×10 3 unit / L, the water body is aging, and the transparency is 25cm; on July 4, 2008, microbial agent was used, 5KG was used per mu, diluted with 100 times of clean water, and evenly sprinkled in the pool. After 5 days, the transparency increased to 40cm; dissolved oxygen increased from 927mg / L increased to 1896mg / L; the number of cyanobacteria decreased to 5200×10 3 / L, the water body has been significantly improved.
