Coated purification deodorant for sewage treatment and preparation process thereof

Abstract

The invention relates to the field of water treatment, and provides a coated purification deodorant for sewage treatment and a preparation process thereof. A slow-release cementing material comprises an inner core, a transition layer and an outer coating layer which are sequentially arranged from inside to outside, wherein the inner core is honeycomb ceramic particles doped with water treatment agent; the transition layer is polyacrylamide gel doped with water treatment agent supported inorganic fibers, the outer coating layer is silica-alumina gel doped with water treatment agent supported composite fibers, the water treatment agent is reasonably coated and designed in a multi-layer mode, multiple purification effects of biological purification and chemical purification are achieved, the sewage treatment efficiency is greatly improved through sequential progressive cooperation, the purifying and deodorizing effects are good, the effect taking is fast, the lasting effect is long, the comprehensive benefits are obviously improved, and the process is worthy of popularization and application.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a coated type purification deodorant for sewage treatment and a preparation process thereof. Background technique [0002] With the continuous development of my country's industrialization process, the chemical industry has played an increasingly important role in the development of my country's economy, but the development of the chemical industry has also brought new environmental problems. Every year, the wastewater produced by the chemical industry will cause difficulties to the environment. Therefore, properly solving the problem of chemical wastewater treatment is the key to achieving the coordinated development of environmental protection and economic growth. [0003] According to the principle of action, chemical wastewater treatment methods can be divided into four categories: physical method, chemical method, physical chemical method and biological method. The p...

Problems solved by technology

Among the above treatment methods, the physical method usually has low treatment efficiency and is only used as a pretreatment method; most of the chemical and physical chemical methods have problems such as high equipment investment and high operating costs, and are rarely used in actual projects; biological treatment has operating costs However, due to the complex water quality of chemical wastewater, high biological toxicity, and poor biochemical properties, it is rarely used alone, and is usually used in combination with physical, chemical, and physical chemical methods.
