Abstract
The invention relates to a production process of a pecan shell water treatment filter material. A raw material of high-quality pecan shell is subjected to crushing, polishing, steaming drug preservative treatment, and two screening to process the filter material. The filter material is applicable to water treatment for oil refining enterprises, has the advantages of high hardness, abrasion resistance, good anti-pressure property and strong adsorption sewage capability, can be directly used in backwash before the filter, and has significant treatment effect for oily wastewater.
Description
Technical field
The present invention relates to a water treatment filter material, specifically a kind of production technology of pecan shell water treatment filter material.
Background technology
Water treatment filler and filtrate are for the carrier mass that the filter media material of materializing strategy and the microorganism of biochemical treatment are perched in water treatment technology, are the links that can not lack of direct relation treatment effect in modern water treatment technology.
In filtering technique, the formation of filtrate and filter material layer is the key determining filter plant performance quality, and they decide the water quality of the rear water of filter, decide the key property of filter plant.Therefore, the research and improvement that form filtrate and filter material layer are depended in the development of filtering technique to a great extent.Along with improving constantly of human living standard, the requirement of people to filtrate is more and more higher.Through years of researches and development, kind and the specification of filtrate are increasing, quality and performance progressively improves, range of application constantly expands, the needs of the national economic development are adapted to, especially obtain good effect at water treatment field, progressively promote progress and the development of China's Water treatment filtration technology.
Summary of the invention
For prior art Problems existing with not enough, technical problem to be solved by this invention is, provides a kind of production technology of pecan shell water treatment filter material, high-quality pecan shell is adopted to be raw material, wash through fragmentation, polishing, steaming, medicine preservative treatment, twice screening processes, and is applicable to the water treatment of petroleum refining enterprise, there is hardness high, the advantages such as wear-resistant, crushing resistance is good, and absorption retaining power is strong, directly can adopt the front backwash of filter, to oily waste water treatment Be very effective.
For solving the problems of the technologies described above, the technical solution used in the present invention is, a kind of pecan shell water treatment filter material production technology, comprises the steps:
The first step, screening, carries out just screening by pecan shell, too broken, have screening out of insect bite;
Second step, broken polishing, utilize crushing mechanism to carry out fragmentation the pecan shell screened, particle diameter reaches 1.6-2mm;
3rd step, steams and washes and medicine preservative treatment, and steaming is washed temperature and reached 80-120 degree Celsius;
4th step, postsearch screening, carries out postsearch screening by the pecan shell filtrate handled well, packaging warehouse-in.
Above-mentioned a kind of pecan shell water treatment filter material production technology, the 3rd step, steams and washes and medicine preservative treatment, and steaming is washed temperature and reached 90 degrees Celsius.
The production technology of pecan shell water treatment filter material of the present invention, high-quality pecan shell is adopted to be raw material, wash through fragmentation, polishing, steaming, medicine preservative treatment, twice screening processes, and is applicable to the water treatment of petroleum refining enterprise, there is hardness high, the advantages such as wear-resistant, crushing resistance is good, and absorption retaining power is strong, directly can adopt the front backwash of filter, to oily waste water treatment Be very effective.
