Problems solved by technology

[0003] Nowadays, there are various types of phosphorus removal agents on the market. Although they can meet people’s needs, there are still some shortcomings. The phosphorus removal effect of the phosphorus removal agents on the market is not good, and the efficiency of phosphorus removal is low. Phosphorus removal agent can complete the purpose of phosphorus removal, and the existing phosphorus removal agent only has phosphorus removal effect, and has no removal effect on other harmful substances in sewage. It has a single function, high manufacturing cost, and complicated manufacturing methods and processes. Increased difficulty of batch preparation

Abstract

The invention discloses a high-efficiency composite phosphorus removal agent and a preparation method thereof, and the preparation method comprises the following steps: step 1, weighing raw materials; step 2, crushing the aggregate; step 3, dissolving and extracting; step 4, mixing and emulsifying; step 5, high-temperature drying; step 6, biological material carbonization; step 7, crushing and mixing; step 8, ultrasonic treatment; and 9, drying and packaging. Coconut shells, straw and dead wood are carbonized and then added into the composite phosphorus removal agent, the carbonized material is rich in pores and large in specific surface area, the adsorption effect of the composite phosphorus removal agent is improved, other harmful substances are removed while phosphorus is removed, calcium ions in shells, pig bones and bovine bones are extracted through hydrochloric acid, soluble calcium ions are obtained, and the calcium ions are added into the composite phosphorus removal agent. Calcium ions and phosphorus elements are easily synthesized into insoluble substances, the phosphorus removal effect and efficiency of the composite phosphorus removal agent are enhanced by cooperating with polyferric chloride and polyaluminum chloride for use, waste is turned into wealth, waste is utilized, economic benefits are improved, and meanwhile environmental protection is facilitated.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a high-efficiency composite dephosphorization agent and a preparation method thereof. Background technique [0002] Phosphorus removal agent is an item for coagulation and turbidity removal treatment of urban water source water and phosphorus removal. It can achieve the purpose of deep phosphorus removal while coagulation and turbidity removal treatment of urban water source water, and reduce the phosphorus content in the treated drinking water to the limit. Below the value, there is no need to change the raw water treatment process, and no need to add large-scale water treatment structures. It is simple, economical and practical, and can obtain significant social and economic benefits. [0003] Nowadays, there are various types of phosphorus removal agents on the market. Although they can meet people’s needs, there are still some deficiencies. The phosphorus removal ef...
