Problems solved by technology

However, the existing common sewage fillers have disadvantages such as complex composition, poor fixation, and poor phosphorus removal effect.
[0004] In addition, the inventor found that in practical applications, the existing various fillers cannot be directly used in conjunction with the corresponding sewage treatment equipment or phosphorus removal / nitrogen removal equipment, and further cutting or processing is required, resulting in waste of fillers; further, the current Some of the phosphorus-removing fillers contain aluminum powder. The aluminum powder used in the preparation process is prone to secondary pollution or even explosion, and the cost of aluminum powder is relatively high, so it is not easy to promote on a large scale.

Embodiment Construction

[0035] In actual implementation, fly ash, diatomaceous earth, cement, and foaming agent can be mixed in a weight ratio of 55:10:10:5, and quicklime and water can be added at the same time.

[0036] During specific preparation, as another preference, block raw materials of fly ash, diatomite and unslaked lime can be used through crushing and grinding; cement powder raw materials can be used directly, and the foaming agent can be made into a concentration of 5 to 5% by weight. 6% solution.

[0037] As a preference, the particle size of the filler is 10-50mm; the specific surface area of ​​the filler is (50-60)×10 4 cm 2 / g;

[0038] The phosphorus adsorption capacity of the filler is 6-6.5mgP / g, and the compressive strength is 4.0-4.5Mpa;

[0039] The density of the filler is 1.0 ~ 1.2g / cm 3 , the bulk density is 0.6~0.75g / cm 3 .

[0040] Concrete preparation method flow process is as follows:

[0041] (1) The fly ash, diatomaceous earth, quicklime, cement, foaming agent ...

Abstract

The invention provides sewage treatment packing and a preparation method of the packing. Besides, sewage can be subjected to high-efficiency phosphorous removal treatment through combination with theprepared packing; meanwhile, the packing can be cut into particles, blocks, columns or balls with corresponding sizes as required in the preparation process, thereby directly cooperating with sewage treatment equipment or phosphorous removal equipment for use, that is, the packing is directly put in an adsorption column or a corresponding adsorbent container of the sewage treatment equipment or the phosphorous removal equipment in a filled manner.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment filler, a preparation method and related uses. Background technique [0002] Sewage treatment is one of the important issues facing environmental protection. With the continuous enhancement of human activities, the nitrogen and phosphorus pollution of water bodies is becoming more and more serious. For example, the eutrophication of water bodies has caused serious water pollution of rivers and lakes; among them, the most important controlling factors are phosphorus and nitrogen; nitrogen and phosphorus elements enter The water directly leads to the eutrophication of the water body, and phosphorus is the deeper cause of the eutrophication of the water body. In addition, the development of urban industry will also discharge a large amount of sewage, and the current situation of extensive farming in rural areas will also lead to the generation of a large amount of...
