Problems solved by technology

[0004] However, if any water treatment method is used alone, the treatment effect achieved is average; and due to the chemical reaction between different methods of treatment agents, the agent becomes invalid, which reduces the treatment efficiency when multiple methods are used in combination; and, the combination of multiple methods It is often impossible to compound the medicaments during use, and can only be treated in sequence, so that the wastewater is treated with different medicaments in sequence. The operation is cumbersome, inefficient, and requires a lot of manpower and material resources, and the treatment cost is high.

preparation example Construction

[0052] The preparation method of iron carbon sphere particles: first, mix and stir iron powder, activated carbon, graphite, calcium carbonate powder, bentonite and attapulgite according to the mass ratio of 6:2:0.5:0.5:0.5:1, and perform wet granulation , dried and sieved to obtain raw material particles; then the obtained raw material particles were transferred to a tube furnace, and sintered at 800°C for 6 hours under the protection of nitrogen to form iron-carbon spherical particles. Among them, calcium carbonate powder can reduce the degradation energy of organic matter during the reaction process, and bentonite and attapulgite can slow down the compaction of iron-carbon sphere particles.

Abstract

The invention relates to a wastewater treatment agent as well as a preparation method and a use method thereof. The wastewater treatment agent comprises a compound A and a compound B; the compound A comprises the following components in part by weight: 20 parts of iron carbon sphere particles and 10 parts of citric acid; the compound B comprises the following components in part by weight: 30 partsof sodium persulfate, 20 parts of encapsulation-type potassium ferrate, 10 parts of lime and 10 parts of diatomite; and the mass ratio of the compound A to the compound B is 1:(2-6). In addition, theinvention further provides the preparation method and the use method of the wastewater treatment agent. According to the wastewater treatment agent prepared by the preparation method provided by theinvention and a method for wastewater treatment by the wastewater treatment agent, the treatment time of wastewater can be effectively shortened, and the degradation rates of various substances in thewastewater are improved.

Description

technical field [0001] The invention relates to water purification treatment technology, in particular to a waste water treatment agent, a preparation method and a use method thereof. Background technique [0002] With the development of urbanization and industrialization in China, the discharge of urban sewage continues to increase, and the amount and type of organic matter entering the water body increase sharply, resulting in serious pollution of water resources. For wastewater containing refractory organic pollutants, traditional biological treatment can no longer meet the treatment requirements, and more effective methods need to be used further. [0003] At present, the most effective method for treating refractory organic pollutants in wastewater is deep oxidation technology. The so-called deep oxidation technology refers to the water treatment technology that uses free radicals (such as OH) generated by advanced oxidants to quickly and completely oxidize organic matt...
