Description

Synchronous dephosphorization system of integration sewage treatment device

Technical Field

The utility model relates to a water treatment technical field especially relates to a synchronous dephosphorization system of integration sewage treatment device.

Background

Phosphorus is a source for causing eutrophication of water, and although the phosphorus content of domestic sewage is very low, the discharge water amount is extremely large. If the water body is directly discharged without being treated, the water environment can be seriously polluted. Phosphorus is an indispensable nutrient for organisms and has no toxicity. However, problems arise when large amounts of phosphorus, copper and other nutrients are discharged into the water. The massive growth of algae causes the imbalance of ecological balance of the water body, resulting in eutrophication of the water body, and the consequences thereof are very serious.

The mass propagation of the algae can quickly reduce the dissolved oxygen in the water, so that aquatic organisms are suffocated and die due to lack of oxygen, and finally the ecological systems of water bodies such as lakes and the like are unbalanced; secondly, after a large number of organisms die in the water body, the corpses of the organisms are oxidized and decomposed to generate some toxic and harmful gases, such as hydrogen sulfide and the like, so that the water quality is deteriorated. Moreover, organic matters secreted by the algae are decomposed to generate substances such as humic acid and the like which are difficult to degrade, and toxic and harmful substances are released; in addition to the above hazards, landscapes are also affected, and water surfaces are easily covered with a large amount of algae, which hinders the beauty of the water body. More notably, people drinking water containing phosphorus for a long time can cause osteoporosis of human bodies and have pathological changes such as necrosis of mandible and the like.

A plurality of sewage treatment processes are adopted at home and abroad, wherein the processes are mainly divided into chemical phosphorus removal and biological phosphorus removal. The chemical phosphorus removal is mainly realized by generating phosphate precipitation with phosphate radical, thereby achieving the effect of phosphorus removal. However, the method removes phosphorus, has more factors influencing the formation of phosphate precipitate, introduces new metal ions, has higher cost for treating wastewater and also influences the effluent effect.

Biological phosphorus removal mainly depends on the action of microorganisms to achieve phosphorus removal. But phosphorus removal mainly depends on the activity of microorganisms, and the activity of the microorganisms is influenced by various factors such as environment, sewage condition, air temperature and the like.

In the process of implementing the present invention, the inventor finds that there are at least the following problems in the prior art:

1. the environmental adaptability is weak, the water needs to be prevented from freezing in winter, and the water outlet is unstable along with seasonal changes.

2. The total phosphorus in the effluent reaches the standard, the effluent needs to be subjected to anaerobic treatment, and the cost of the tank body is increased;

3. the requirement on the debugging personnel is higher.
