Abstract
The invention discloses a landscape lake water replenishing and phosphorus control process, and belongs to the technical field of sewage purification. The process is simple in steps and convenient tooperate, the oxygen content in water does not need to be controlled, calcium ions of calcium carbonate and phosphate ions in water can generate hydroxyl calcium phosphate, the hydroxyl calcium phosphate precipitates downwards, and calcium ions released by calcium carbonate on the lower layer are not influenced; no filtering device needs to be placed in the phosphorus removal process, the replacement cost of the filtering device is reduced, meanwhile, the cleaning time of the filtering device is also saved, and in addition, only similar water needs to be purified. The purification process can be suitable for various sewage purification projects with different scales, can also ensure the ecological safety in the purification process, is scientific and reasonable, is safe and convenient to use, is low in calcium carbonate price, is very easy to purchase, and is convenient to popularize and apply.
