Abstract
The invention provides a peanut shell activated carbon water treatment agent. The peanut shell activated carbon water treatment agent consists of a peanut shell, an activator and water. A preparation method of the peanut shell activated carbon water treatment agent comprises the following steps: by taking the crushed peanut shell as a raw material and oxalic acid as the activator, dipping for 24h, adjusting the power of a microwave oven to reach 900W, with the irradiation time of 10min, and then washing a product obtained by irradiation (washing the activated material with warm water to enable the pH value of the activated material to be close to 7), and drying and crushing to obtain finished activated carbon. The average particle size of the peanut shell activated carbon prepared by utilizing a microwave method is about 50 microns, and carbon and oxygen elements of the peanut shell activated carbon are significantly lost, which shows that under the effect of high temperature, CO2 is generated by the combination of carbon and oxygen and is released, thereby causing a large number of pores inside the activated carbon. The saturated adsorption time of the product is 120min, and the adsorption effect is good at a relatively high temperature (50 DEG C).
Description
Technical field
The invention belongs to water treatment agent field, particularly relate to a kind of Activated Carbon Made from Peanut Shells water treatment agent.
Background technology
Global shortage of water resources problem has caused mondial great attention.Along with the development of China's economy, environmental pressure also constantly increases the weight of, and problem of environmental pollution has become China's problem demanding prompt solution.But China's industrial water consumption is but wasted surprising; main cause is that recycling rate of water used by the industries is lower; therefore; improve the service efficiency of industry or civilian recirculated water; adopt environmentally friendly water treatment agent, saving water resource, reduction production cost and protection of the environment are all had very important significance.
The method of the process waste water of current use mainly contains: physical partition method, biological degradation method, chemical decomposition method, but these methods all have some limitations, and are unfavorable for sustainable development.Thus, people start to be devoted to develop efficient, low energy consumption, applied widely and have the pollutant clearance technique of deep oxidation ability.
Active carbon, owing to having efficient suction-operated, makes it have a wide range of applications in fields such as industry, scientific research, national defence.In recent years, water factory is to organic matter, pigment, interfacial agent and the foul smell etc. in the advanced treating of running water also in extensive use charcoal absorption water.Active carbon in use can lose vigor gradually, finally loses adsorption capacity.Because the regeneration cost of current active carbon is higher, and regeneration rate neither be too high, therefore the active carbon losing adsorption capacity of use about 3 years is normally worked as offal treatment by water treatment plant, so not only wastes resource and adds operating cost, and easily cause environmental pollution.
At present, domestic industry enterprise uses reverse osmosis membrane (RO) technology to carry out technique waste water Treatment for Reuse mostly, but existing RO treatment process ubiquity easily blocking, cleaning is frequent, pollutant removal is not thorough, aquifer yield is low, the shortcomings such as operating pressure is high, one of the main reasons is that in former water, electrolyte concentration is larger, although the pretreating process adding inorganic coagulant of routine can remove part heavy metal ion, the pollutants such as organic matter, but electrolyte concentration in water can not be reduced to greatest extent, namely the electrical conductivity in water can not effectively be reduced, there are some researches show: the increase fouling with electrical conductivity will be more and more serious.Therefore, the electrical conductivity in counter-infiltration system water inlet will have an impact to aquifer yield.
Summary of the invention
The object of the invention is to overcome the production method that the deficiencies in the prior art provide a kind of active carbon, and the method is with low cost, simplifies production routine, technique is simple; The water treatment agent of preparation is applicable to the advanced treating of various waste water, environmental protection non-secondary pollution.
Its preparation method is: using the peanut shell that crushes as raw material, take oxalic acid as activator, dipping 24h, and adjustment microwave power reaches 900W, exposure time 10min, then washes irradiation products obtained therefrom and (use warm water washing activated material, make its pH value.Close to 7), drying, pulverize and to get product active carbon.
Beneficial effect of the present invention:
(1) material source of the present invention is extensive, with low cost, and technique is simple, and low to the requirement of equipment, operability is good;
(2) water treatment agent that prepared by the present invention can remove water middle and high concentration organic pollution, is applicable to the advanced treating of various waste water, environmental protection non-secondary pollution, and has antibacterial, deodorizing, can adsorb the advantages such as other heavy metal ion; Water treatment efficiency is good, can be recycled, and can promote at water treatment field, has significant practical value and wide market prospects.

The average grain diameter of the Activated Carbon Made from Peanut Shells utilizing microwave method to prepare is about 50um, and its carbon and oxygen element have significantly lost, and this illustrates under high temperature action, and carbon and oxygen combine and generates CO2 and discharge, and causes the hole that active carbon is inner a large amount of.The saturated adsorption time of this product is 120min, and when temperature is higher, (50 DEG C) adsorption effect is better.
