DETAILED DESCRIPTION

[0017] To make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Identical parts are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.

[0018] The ingredients of the biological agent include a combination of multiple organic nitrogen sources, a complex amino acid system, a vitamin complex and a trace element chelate group;

[0019] Diverse organic nitrogen source combination: Carefully selected high-quality peptones, including tryptone and casein peptone, are rich in peptides and amino acids. They can provide microorganisms with sufficient and diverse nitrogen sources, meeting the specific nitrogen requirements of different microbial species during growth and reproduction, effectively promoting the proliferation of microorganisms and enhancing metabolic activity.

[0020] Composite amino acid system: It covers a variety of essential amino acids such as lysine, methionine, tryptophan and threonine, as well as other non-essential amino acids with important physiological functions. These amino acids can not only be directly absorbed and utilized by microorganisms, accelerating the protein synthesis and cell renewal process of microorganisms, but also play a key catalytic and regulatory role in the enzymatic reactions and energy metabolism of microorganisms, further enhancing the overall activity of microorganisms and their ability to decompose and transform pollutants in sewage;

[0021] Vitamin complex: including B vitamins, vitamin C and vitamin E. Vitamins play an indispensable role as coenzymes and antioxidants in the growth and development of microorganisms. They participate in many key physiological and biochemical reactions, such as cellular respiration, electron transfer, and antioxidant defense. They can significantly improve the stress resistance and environmental adaptability of microorganisms, ensuring that microorganisms maintain high activity and stability in complex and changeable sewage environments.

[0022] Trace element chelate group: composed of chelates formed by trace elements such as iron, manganese, zinc, copper, molybdenum, and boron and specific chelating agents. These trace element chelates can effectively prevent the precipitation and inactivation of trace elements in the solution, ensuring that they exist in a form that can be efficiently absorbed and utilized by microorganisms. They play a vital role in the composition of microbial enzyme active centers, gene expression regulation, and maintenance of cell membrane stability, providing strong guarantees for the normal growth, reproduction, and stable operation of metabolic functions of microorganisms.

[0023] B vitamins such as thiamine, riboflavin, niacin, pantothenic acid, and biotin.

[0024] Certain chelating agents include ethylenediaminetetraacetic acid and diethylenetriaminepentaacetic acid.

[0025] The steps of preparing a biological agent for sewage treatment are as follows:

[0026] All types of raw materials are strictly screened and quality tested to ensure that their purity and activity meet high standards. For organic raw materials such as peptone and amino acids, advanced ultrafiltration and reverse osmosis technologies are used to remove impurities, salts and harmful microorganisms, while ensuring the integrity and effectiveness of nutrients. For trace element chelates, high performance liquid chromatography is used for precise analysis and quality control to ensure the accuracy of chelation effect and trace element content.

[0027] According to the pre-designed optimized formula ratio, with the help of a high-precision automated batching system, pretreated peptone, amino acids, vitamin complexes and trace element chelates are added in sequence to strictly sterilized deionized water. In a constant temperature environment of 28-32°C, high-speed stirring equipment is used to continuously stir at a speed of 200-300 rpm for 45-60 minutes to ensure that all ingredients are fully dissolved and evenly mixed to form a stable and uniform nutrient matrix solution. During this process, the pH value, conductivity and other parameters of the solution are monitored in real time, and fine-tuning is performed as needed to ensure the chemical stability and biocompatibility of the nutrient.

[0028] The prepared microbial nutrient solution is sterilized by sterile filtration equipment to remove any residual microorganisms and impurity particles to ensure the sterility of the product. Subsequently, the nutrient solution is packaged in a specific packaging container using aseptic packaging technology.

[0029] The application of biological agents in sewage treatment is to set up an online water quality monitoring system at the water inlet of the sewage treatment plant to continuously monitor the carbon, nitrogen, phosphorus content of the sewage as well as key water quality parameters such as pH value, water temperature, dissolved oxygen, etc. in real time. Based on the dynamic changes of the influent water quality, big data analysis and intelligent algorithms are used to accurately calculate the type and addition amount of the required microbial nutrients, ensuring that the carbon, nitrogen and phosphorus ratios in the sewage can be quickly adjusted to the optimal range suitable for microbial growth and metabolism, and then the nutrients are added. Efficient hydraulic stirring devices or aeration equipment are set near the addition point. Through strong hydraulic stirring and aeration, the nutrients can be quickly and evenly mixed with the sewage in a short time, ensuring that the microorganisms can obtain nutrients in a timely and uniform manner. In order to maximize the activation and promotion effect of nutrients, a series of advanced monitoring instruments and sensors are installed in the sewage biochemical treatment system, such as microbial respiration rate meters, sludge activity detectors, water quality online analyzers, etc., to track and monitor key indicators such as changes in microbial activity, sludge sedimentation performance, and removal efficiency of pollutants in sewage in real time. According to the feedback from monitoring data, the dosage, frequency, and method of microbial nutrients are adjusted in time to achieve dynamic optimization and refined management of the sewage treatment process, ensure that the biochemical system always maintains an efficient and stable operating state, and can quickly recover and maintain normal treatment capacity even when the influent water quality fluctuates violently or is impacted.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
