Problems solved by technology

If the naturally occurring VFA content is insufficient, it is necessary to add VFA in the anaerobic section, and the steps are relatively cumbersome
[0004] The steps of the above-mentioned phosphorus removal process are relatively cumbersome, the effect of phosphorus removal is not very good, and the environment of the sewage during phosphorus removal needs to be controlled, so a new phosphorus control process is needed to solve the above problems

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.

Description

technical field [0001] The invention relates to the technical field of sewage purification, in particular to a process for replenishing water and controlling phosphorus in landscape lakes. Background technique [0002] In the prior art, most of the methods of phosphorus removal in sewage are biological phosphorus removal, which means that aerobic bacteria will nitrify and decompose organic phosphorus or partial phosphorus under certain conditions, and a part of phosphorus will be absorbed by microorganisms, thus becoming It is microbial sludge; another part of phosphorus will be decomposed and converted into small orthophosphorus molecules. In the subsequent treatment, small orthophosphorus molecules will continue to be precipitated by chemical methods. In terms of phosphorus removal efficiency, the biological phosphorus removal method cannot treat phosphorus to a low concentration. The first reason is that the ability of microorganisms to decompose organic phosphorus is lim...
