For these white clays containing 20-30% oil, some manufacturers will carry out secondary deep pressing to obtain mixed oil and waste white clay containing 5-8% oil. If you want to get oil from this waste white clay, the cost will be high , so manufacturers will treat it as waste. Due to the high processing cost, most of the oily waste soil in oil factories will be piled up or buried, which will cause environmental pollution, waste resources, and affect the sustainable development of resources and the environment.

Embodiment 1
[0028] A phenol-containing wastewater treatment agent, the raw material formula of which is: 30% of modified waste clay, 5% of ammonia water, 10% of zinc dihydrogen phosphate, 6% of microbial bacteria and 49% of cross-linked rectorite. The microbial bacterium is Pseudomonas phenololyticum (the bacterium is recovered and activated with medium first, and then the bacterium in logarithmic growth phase is domesticated for 5 days).
[0029] The preparation method of phenolic wastewater treatment agent is as follows:
[0030] (1) Heat 750kg of waste clay containing grease to 60°C, then add 150kg of citric acid and stir for 3 hours, and finally add 100kg of cellulose, stir and react at 80°C for 2 hours to obtain modified waste clay, and cool down to 30°C ;
[0031] (2) Add zinc dihydrogen phosphate to the modified waste clay, adjust the pH with ammonia water, the pH is about 7.5, then add microbial bacteria to stir, and balance for 5 days at a temperature of 30°C, and finally add th...
Embodiment 2
[0033] A phenol-containing wastewater treatment agent, the raw material formula of which is: 50% of modified waste clay, 7% of ammonia water, 5% of zinc dihydrogen phosphate, 6% of microbial bacteria and 32% of cross-linked rectorite. The microbial bacteria are Bacillus sphaericus, which are activated and domesticated before use.
[0034] The preparation method of phenolic wastewater treatment agent is as follows:
[0035] (1) Heat 500kg of waste clay containing grease to 80°C, then add 125kg of citric acid and stir for 2 hours, and finally add 100kg of cellulose, stir and react at 80°C for 3 hours to obtain modified waste clay, and cool down to 30°C ;
[0036] (2) Add zinc dihydrogen phosphate to the modified waste clay, adjust the pH with ammonia water, and control the pH to about 7.5, then add microorganisms and stir, and balance for 5 days at a temperature of 30°C, and finally add crosslinking Rectorite, stir evenly.
Embodiment 3
[0038] A phenol-containing wastewater treatment agent, the raw material formula of which is: 40% of modified waste clay, 5% of ammonia water, 10% of zinc dihydrogen phosphate, 6% of microbial bacteria and 39% of cross-linked rectorite. Wherein the preparation of microbial bacterium and treatment agent is with embodiment 1.

Abstract
The invention relates to a phenol-containing wastewater treatment agent and a preparation method thereof. The phenol-containing wastewater treatment agent is prepared from the following raw materials: 20 to 60 percent of modified waste clay, 1 to 7 percent of ammonia, 2 to 10 percent of zinc dihydrogen phosphate, 0.5 to 7.5 percent of microbial bacteria and 15.5 to 76.5 percent of cross-linked rectorite. The modified waste clay is prepared by heating greasy waste clay to 35 to 80 DEG C, adding citric acid and reacting under stirring for 2 to 3 hours, adding cellulose and reacting under stirring at a temperature of 60 to 80 DEG C. The preparation method of the treatment agent comprises the following steps: adding the zinc dihydrogen phosphate to the modified waste clay, adjusting the pH value to 7 to 9 with ammonia water, then adding the microbial bacteria and stirring, equilibrating for 5 to 6 days at a temperature of 28 to 35 DEG C, and finally adding the cross-linked rectorite, and stirring evenly. The phenol-containing wastewater treatment agent provided by the invention has a very good treatment effect and is prepared by using waste clay as a raw material, thereby realizing resource recycling and remarkably reducing the cost.
Description
technical field [0001] The invention relates to the field of phenol-containing wastewater treatment, in particular to a phenol-containing wastewater treatment agent and a treatment method. Background technique [0002] Under the highly developed modern civilization, industrial wastewater, urban sewage and domestic water are discharged, and a large amount of pollutants flow into rivers and lakes without treatment, making the river water suffer from organic pollution and become eutrophic water. As we all know, phenol-containing wastewater is one of the most harmful toxic wastewater, which is highly toxic and biodegradable to all organisms. In 1977, phenol-containing wastewater was listed as 129 kinds of limited control by the US National Environmental Protection Agency. It is one of the pollutants, and it is also one of the harmful wastewater that is mainly solved in my country's current water pollution control and the three wastes treatment objects that need to be solved urgen...
