Embodiment 1

[0033] A treatment agent for improving biochemical purification efficiency of sewage, which comprises the following components in parts by weight: 80 parts of diatomite, 10 parts of biological growth stimulator (a mixture of lanthanum chloride and ferric chloride in a weight ratio of 1:5) , 90 parts of biological nutrients (the mixture of glucose and acetate in a weight ratio of 10:50, the weight of glucose and acetate is based on the weight of carbon element respectively);

[0034] Preparation:

[0035] (1) Mix lanthanum chloride and ferric chloride in a ratio of 1:5 by weight to form a biological growth stimulant, dissolve 10 parts of the biological growth stimulant in water, and make a solution with a total concentration of 0.1mol / L ;

[0036] (2) immerse 80 parts of diatomaceous earth in the solution obtained in step (1) for 5 hours, dry at 80°C to constant weight, and then roast at 600°C for 5h to make the primary treatment agent;

[0037] (3) the mixture of glucose and...

Embodiment 2

[0043] A treatment agent for improving biochemical purification efficiency of sewage, which comprises the following components in parts by weight: 60 parts of activated carbon, 20 parts of biological growth stimulator (a mixture of cerium nitrate and iron nitrate in a weight ratio of 1:5), biological nutrient 120 parts (the mixture of glucose, acetate and phosphate in a weight ratio of 1:10:5, the weight of glucose and acetate is calculated by the weight of carbon element, and the weight of phosphate is calculated by the weight of phosphorus element);

[0044] Preparation:

[0045] (1) Cerium nitrate and ferric nitrate are mixed in a ratio of 1:5 by weight to form a biological growth stimulator, and 20 parts of biological growth stimulants are dissolved in water to form a solution with a total concentration of 0.05mol / L;

[0046] (2) immerse 120 parts of activated carbon in the solution obtained in step (1) for 2 hours, dry at 100°C to constant weight, and then roast at 500°C ...

Abstract

The invention discloses a primer for improving biochemical and purifying efficacy of sewage, comprising the following components in parts by weight: 50-100 parts of carrier, 1-20 parts of biological growth stimulant and 10-150 parts of biological nutritional agent. The invention also discloses a preparation method and an application method of the above primer. The primer of the invention is used in the middle and rear stages for processing structures by an activated sludge method so as to improve the activation of activated sludge and improve purification effect.

Description

technical field [0001] The invention belongs to the field of sewage treatment engineering, and in particular relates to a treatment agent for improving the efficiency of sewage biochemical purification, a preparation method and a use method thereof. Background technique [0002] Activated sludge process is the mainstream method of wastewater treatment. The process is simple, the operation and control are more convenient, and it is widely used in wastewater treatment. With the development of modern industry in recent years, the waste water containing various toxic organic pollutants is increasing day by day, and the treatment is very difficult. Especially in the development of industrial parks, the collected wastewater has complex components and great differences in biochemical properties. Taking printing and dyeing comprehensive wastewater as an example, the wastewater contains not only easily biodegradable pollutants such as starch, but also difficult biodegradable pollut...
