The invention relates to a zero discharge treatment method of VOCs waste gases. The method comprises the following steps: treating organic matters, namely carrying out organic matter treatment on waste gases generated by VOCs waste gas sources, wherein the organic matter treatment adopts one or a combination of more of an assimilation recycling method, an adsorption recycling method, a condensation recycling method, an incineration method, a catalytic incineration method, a plasma method and a biological method to remove VOCs in the waste gases; recycling exhaust gases, namely returning the waste gases subjected to the organic matter treatment to the VOCs waste gas sources. With the adoption of the zero discharge treatment method of the VOCs waste gases, zero discharge of the VOCs waste gases is realized, the technical problem of the zero discharge of the VOCs waste gases which is desired to be solved but cannot be solved by environmental protection equipment manufacturing enterprises over the years is overcome, and emission pollution of the VOCs waste gases to the environment is completely eliminated; the whole treatment process is simple and easy to operate and high in treatment efficiency, requires less equipment, has low energy consumption of the equipment, well meets requirements of modern enterprises on energy saving and emission reduction, improves requirements of production benefits and has great significance on saving resources and reducing costs.

The invention provides a method for producing a compound microbial fertilizer by a microbial inoculum coating method, comprising the following steps of: preparing solid microbial inoculum; adding abamectin waste liquid to an inorganic fertilizer and pelletizing to prepare organic fertilizer particles; compounding the organic fertilizer particles with the solid powdery microbial inoculum, wherein the weight proportion of the microbial inoculum to the finished-product compound microbial manure is 5-15%; and mixing and then drying, wherein the temperature of materials in a drying cylinder is not higher than 80 DEG C. The method for preparing the granular compound microbial fertilizer is divided into two steps of organic granule pelletization and organic granule coating, which ensures the certain viable count in the compound microbial fertilizer; the products of the compound microbial fertilizer realize the breakthrough from powdery form and disc and drum pelletization to guniting pelletization, which lays a foundation for improving commodity value, effectiveness and area promotion of the compound microbial manure; in addition, the invention simultaneously finds out a way with high added value for the resource utilization of the abamectin waste liquid.

The invention provides a method for producing a compound microbial fertilizer with insecticidal effect, comprising the following steps: preparing liquid microbial agent; adding waste abamectin liquid to inorganic fertilizer, and granulating the inorganic fertilizer into granular organic fertilizer; compounding the granular organic fertilizer and the liquid microbial agent which is 0.5-1.5 percent of the weight of the finished product of the compound microbial fertilizer; and airing or drying. The invention breaks the normal method for producing the compound microbial fertilizer and provides a novel method for producing the granular compound microbial fertilizer by granulating the inorganic fertilizer into the organic fertilizer and coating the liquid microbial agent by the granular organic fertilizer. The powdery compound microbial fertilizer is replaced by the granular compound microbial fertilizer, and the granular compound microbial fertilizer has a certain activity, thus a good foundation is laid for popularizing the granular compound microbial fertilizer on a large scale. The invention also provides a method for recycling the waste abamectin liquid.

The invention provides a production method of granular bioorganic fertilizer. The preparation method comprises steps of preparing a liquid microbial preparation, making organic granules from amino acid waste liquid and organic matter raw material, and mixing organic granules with the liquid microbial preparation. The liquid microbial preparation is uniformly adsorbed on the surfaces of amino acid organic granule, and the addition proportion in bioorganic fertilizer finished product is 0.5-1.5 wt%. The production method breaks the normal procedures, adopts granulation of organic granules and adsorption of liquid microbial preparation onto the organic granules, and ensures certain viable count in the bioorganic fertilizer. The bioorganic fertilizer product realizes the breakthrough from powder, pan or drum granulation to spray granulation, and lays a foundation for improving the commercial quality and the effectiveness of the bioorganic fertilizer and promoting the bioorganic fertilizer.
