Abstract

The invention belongs to the technical field of water treatment, and relates to a preparation technology of a banana peel polymer coagulant for water treatment, which mainly adopts the "low temperature water extraction method" at 30°C to 50°C, including the following steps: (1) Under the condition of temperature and stirring, a certain amount of water is added to the crushed banana peel powder for leaching; (2) under the condition of certain temperature and stirring, add a small amount of sodium hydroxide solution; (3) optionally add A certain amount of sodium hypochlorite and stabilizer to obtain coagulant products with different effects and stability. The technology of the present invention can prepare a kind of banana peel utilization rate is higher, and preparation cost is lower, and effluent pH value is in neutral or slightly alkaline range, and stability is better, and water treatment effect is more excellent, especially to chromaticity, Banana peel polymer coagulant for water treatment with high heavy metal removal efficiency. The banana peel polymer coagulant for water treatment in the present invention can be widely used in the fields of drinking water, urban sewage, industrial waste water and the like.

Description

technical field

[0001] The invention belongs to the technical field of water treatment, and relates to a preparation technology of a banana peel polymer coagulant for water treatment using banana peel as a raw material. Background technique

[0002] The coagulation process is one of the most commonly used unit operations in many water treatment technologies, and it belongs to the physical and chemical treatment method of water. By adding coagulants (or water purifiers, flocculants) to water and waste water, the colloidal substances or smaller suspended solids that are difficult to settle are coagulated and flocculated, and then precipitated and separated to make drinking water and waste water All kinds of sewage (waste) water are purified. In drinking water treatment, coagulation, as an essential pre-operation process in the surface water purification process, can reduce the turbidity, color and other related physical and chemical indicators of raw water, and can also remov...
