Problems solved by technology

Doing so will also have other adverse effects, such as: causing pipeline scaling or corrosion of equipment; phosphate radicals and metal ions in wastewater precipitate, and the sludge contains high inorganic matter, which affects sludge settling or increases the amount of remaining sludge; Due to the low absorption rate of phosphorus, the phosphorus content in the effluent exceeds the standard, which increases new pollution and wastes phosphorus

Embodiment 3

[0046] The biologically active phosphorus nutrient obtained in Example 2 is used in the sewage treatment plant of the petrochemical plant, and after dilution and mixing are uniformly made using the original disodium hydrogen phosphate device, it is added into the pH adjustment tank with a metering pump, and The pretreated water is fully mixed, and then enters the biochemical treatment section to provide nutrients such as phosphorus required for the growth of activated sludge.

[0047] The effect is as follows:

[0048] (1) The average COD removal rate of the biochemical system reaches 90.12%, and the highest value reaches 94.3%, which is about 8 percentage points higher than before use on average.

[0049] (2) The sludge concentration in the aeration tank decreased significantly, the average value decreased from 31181mg / l before use to 28568mg / l, an average decrease of 8.3%, which effectively reduced the total amount of sludge in the system.

[0050] (3) The content of organi...

Abstract

The invention provides a bioactive phosphorus nutritional agent which comprises one or more of phosphorus pentoxide, phosphoric acid or a phosphorus-containing salt and also comprises trace element salts, organic acid, carbohydrate, deep-sea alga, enzymes, an alkyl polyglycoside surface active agent and a fat-soluble pollen extract. The bioactive phosphorus nutritional agent can be pointedly used for industrial waste water which is lack of phosphorus nutrition so as to solve the problem of the undergrowth of active sludge due to the lack of the phosphorus nutrition in biochemical treatment. By utilizing the bioactive phosphorus nutritional agent, the dosage of phosphorus can be greatly reduced so as to avoid the waste and the new pollution of phosphorus.

Description

technical field [0001] The invention relates to the field of environment, in particular to a biologically active phosphorus nutrient used for wastewater treatment. Background technique [0002] The use of activated sludge to treat wastewater is a common treatment method. However, some wastewater, such as the lack of phosphorus in papermaking wastewater, will cause the growth of activated sludge microorganisms due to the lack of phosphorus nutrition, which will affect the treatment effect. [0003] The usual solution is to add a phosphorus nutrient source, such as phosphoric acid or phosphate salts, to the wastewater. Doing so will also have other adverse effects, such as: causing pipe scaling or corrosion of equipment; phosphate radicals and metal ions in wastewater precipitate, and the sludge contains high inorganic matter, which affects sludge settling or increases the amount of remaining sludge; Due to the low absorption rate of phosphorus, the phosphorus content in the ...
