3. water body treating example
The water body administered is Wuhan City river, and flow is greater than 200,000 ton/days, and there are agricultural and aquaculture wastewater in upstream
It imports, nutriment is rich in water, leads to water body extreme eutrophication, becomes black smelly water, seriously affect the water environment in the river.
At the Zhou Qiao of Baima, total phosphorus is up to 5mg/L, and total nitrogen is up to about 40mg/L, and wherein ammonia nitrogen is up to about 20mg/L.
We establish fence at the sewage remittance in the river at this plan, are separated out processing pond 1, but since water is too big,
Fence is easy to be washed away.Complex microorganism preparations are periodically launched thereto, but effect is not obvious.We guess, Ke Nengyuan
Although because being to have launched complex microorganism preparations, since the microorganism cast does not have suitable surface to carry out fixation, quilt
Flowing water washes away, and does not have the effect of enrichment nutrient.Further, since many microorganisms must have anchor surface that could have height
The metabolism of effect, the microorganism to suspend in water can not efficient fixed nitrogen and phosphorus.
Based on considerations above, we are provided with a microorganism attachment device 1 in processing pond 1, and in the water being immersed in,
