With the rise and development of the aquaculture instry in the soft-shelled turtle, pond culture discharge water increasingly serious threat to the surrounding environment also.This paper, Eichhornia crassipes, Bacillus subtilis, snail as a test material handling objects, as a man-made ditch water discharge of waste water, soft-shelled turtle breeding spectrophotometer was monitored ring the test water total nitrogen (TN), total phosphorus (TP)content changes.The results show that, Eichhornia crassipes - Bacillus subtilis - snail three joint processing of water, nitrogen and phosphorus removal effect is remarkable. According to the test ring the data show, the total nitrogen content by 6.3148mg / L of dropped 0.492162mg / L, TN removal rate of 92.20%; TP down of to 0.13652mg / L 1.278mg / L, removal rate reached 89.31% .Superior from the results, the effect of Eichhornia crassipes - Bacillus subtilis - snail Joint repair of soft-shelled turtle farming water, the preferred biological combination can be used as a water body restoration.热心网友 时间:2023-11-16 10:02
With the rise and development of soft-shelled turtle aquaculture, aquaculture ponds drain water to the surrounding environment of the escalating threat. The water hyacinth, Bacillus subtilis, snail as test material, the soft-shelled turtle aquaculture wastewater artificial ditch water as the processing object, using spectrophotometer method monitoring test ring water total nitrogen ( TN ), total phosphorus ( TP ) content change. The results show that, water hyacinth and Bacillus subtilis - snail three to water treatment, nitrogen and phosphorus removal effect. According to the test data ring the show, total nitrogen content from 6.3148mg/L to 0.492162mg/L, TN removal rate reached 92.20%; TP decreased from 1.278mg/L to 0.13652mg/L, the removal rate of 89.31%. From the results, water hyacinth and Bacillus subtilis - snail joint on turtle breeding water body restoration effect is good, can be used as the preferred biological combined water restoration.热心网友 时间:2023-11-16 10:03

Along with the Chinese turtle in the rise and development of the animal husbandry, breeding pond water discharge on the surrounding the threat to the environment is increasingly serious. This paper using eichhorina crassipes, bacillus subtilis, spiral lions as test material, with Chinese turtle breeding wastewater of artificial ditch water as treatment object, using spectrophotometer method monitoring ring the trial of water in total nitrogen (TN) and total phosphorus (TP) content changes. The results show that eichhorina crassipes - bacillus subtilis - three water snails to joint processing, denitrification and dephosphorization effect is remarkable. According to the test period data show that the total nitrogen content from 6.3148 mg/L fell to 0.492162 mg/L, TN removal rate of 92.20%; TP from 1.278 mg/L fell to 0.13652 mg/L, removal rate reached 89.31%. From the result, the eichhorina crassipes - bacillus subtilis - the snails combined the lumen of aquaculture repair effect is superior, can be used as the preferred water body restoration biological combination.热心网友 时间:2023-11-16 10:04
