Problems solved by technology

Methanol is toxic, flammable, and explosive. It is dangerous to transport and store, and only some denitrifying bacteria can use methanol as a carbon source. The COD in the effluent is often high, which limits the application of methanol. The market is gradually using dangerous Sodium acetate trihydrate, a substance with less toxicity and less environmental risk
However, the concentration of sodium acetate is generally 10%~20%, the content is low, the dosage and transportation volume are large, and the theoretical calculation of the amount of substances consumed to remove 1 ton of nitrate nitrogen is to transport 1 ton of sodium acetate trihydrate. Compared with the transportation of about 0.31 tons of methanol, the storage and transportation costs are relatively high
The addition of a large amount of sodium acetate leads to a high sludge yield, which is manifested as an increase in the amount of residual sludge and an increase in the cost of sludge treatment and disposal. It is almost impossible to add sodium acetate on a large scale in sewage plants
In addition, sodium acetate is easy to crystallize and precipitate, and its solubility is low at low temperature, so it is not suitable for use in northern water plants in winter

Abstract

The invention discloses a power source growth promoting composite agent which is prepared from the following raw materials in parts by mass: 2.5-5 parts of calcium acetate, 0.5-2.5 parts of acetic acid, 5-15 parts of sodium acetate, 5-15 parts of ethanol, 10-20 parts of brown granulated sugar or molasses, 0.2-1 part of ferric chloride, 0.5-2 parts of manganese chloride and 0.5-3 parts of biological enzyme.

Description

technical field [0001] The invention relates to the field of preparation of chemical medicaments, in particular to a power source growth-promoting composite medicament and a preparation method thereof. Background technique [0002] In recent years, with the accelerated development of urban processes and industries, the amount of sewage discharge has increased year by year, and the country has higher and higher requirements for sewage treatment. The standard of class A is raised to quasi-class IV, or even higher. The core indicators after upgrading and transformation are SS, total nitrogen, and total phosphorus concentrations in the effluent. For the upgrading of SS and total phosphorus, it can be achieved by strengthening chemical phosphorus removal and efficient precipitation separation, and the upgrading of total nitrogen becomes the current sewage The bottleneck problem of the factory. [0003] For the removal of total nitrogen, sewage treatment plants mainly through bi...
