Problems solved by technology

In the prior art, rubber processing plants mostly use anaerobic and facultative pond systems, oxidation pond systems, activated sludge systems, biological turntable methods, ground discharge, etc. to treat rubber production wastewater. These methods are not perfect, both The organic matter in the wastewater cannot be used as a resource, nor can the wastewater meet the national discharge standards; another treatment method is to use methane bacteria to anaerobically ferment the wastewater to generate biogas, which is used as part of the heat source for drying rubber, but the fermented The waste liquid still does not meet the national discharge standards; another treatment method is to make the rubber waste water into liquid fertilizer directly through liquid fermentation. The concentration of the liquid fertilizer obtained by this method is too low, and it is inconvenient to transport during the sales process, and the transportation cost is high.

Embodiment 1

[0009] 80 tons of pineapple peel, pineapple core, passion fruit skin, passion fruit seeds and other pomace (approximately 15 tons of dry matter) and 20 tons of sawdust (approximately 15 tons of dry matter), fermented microbial flora culture agent, mixed evenly It is a solid material, which is made into a stockpile and fermented. When the temperature of the stockpile rises above 70°C, the stockpile is turned over. After turning over the stockpile, the temperature of the stockpile drops. After the waste water, the moisture content in the solid material reaches 65%. After that, the rubber waste water is injected every 2 days. The ratio of the injection amount of the rubber waste water to the dry weight of the solid material is 1:1. Fermentation, and finally, 35 tons of finished bio-organic fertilizers were obtained.

[0010] The high-temperature fermentation process evaporates and removes excess water in rubber wastewater. At the same time, the solids in rubber wastewater are con...

Embodiment 2

[0012] Mix 30 tons of chaff, 10 tons of rubber oil, 10 tons of sawdust, and fermented microbial flora culture agent to form a solid material. Use rubber waste water to adjust the moisture content of the solid material to about 65% to make a material with a height of 80 cm. When the pile temperature rises above 70°C, turn the pile. After turning over, the pile temperature drops. When the pile temperature rises above 70°C again, inject rubber wastewater into the pile to make the moisture content in the solid material reach 70%. After that, rubber waste water was injected every 2 days, and the ratio of the amount of rubber waste water injected to the dry weight of solid materials was 1:1.25 each time. After the fifth water injection, the pile was immediately turned over for post-fermentation. Finally, 51 tons of finished bio-organic fertilizers were obtained. . The high-temperature fermentation process evaporates and removes excess water in rubber wastewater. At the same time, th...

Abstract

The invention discloses a treatment method of rubber production wastewater. The rubber wastewater is adsorbed by a solid material, wherein the solid material is a biological organic material which is a single raw material or mixed material of plant residues such as sawdust, chaff, straw, pericarp and pomace, leftovers in production of agricultural products and the like; the rubber wastewater is added into the solid material so that the total water content of the solid material is 60-70%; and the solid material is fermented at the temperature of 70-85 DEG C in the presence of fermentation microbe groups, wherein during the fermentation, the rubber wastewater can be injected into the solid material stack for multiple times, and the fermentation microbe groups are high-temperature fermentation microbe groups. In the method provided by the invention, the concentration and conversion of the rubber wastewater are performed at the same time, per ton of solid carrier can absorb 4-6 tons of wastewater to prepare more than 1 ton of organic fertilizer, the rubber wastewater is completely utilized without odor and pollution, and wastes are turned into valuable things; and compared with the prior art, the method provided by the invention has the advantages of environmental-friendly benefits, social benefits and relatively high economic benefits.

Description

Technical field [0001] The invention belongs to a treatment method for waste water, in particular to a treatment method for resource utilization of rubber production waste water. Background technique [0002] Rubber production wastewater has the characteristics of acidity, high solid content, and high nitrogen content. The acidity is caused by the use of coagulants such as acetic acid, formic acid, and sulfuric acid in the rubber production process. The rubber production wastewater is discharged into the environment to corrupt and produce stench. Seriously affect the lives of residents. In the prior art, rubber processing plants mostly use anaerobic and facultative pond systems, oxidation pond systems, activated sludge systems, biological turntable methods, ground discharge, etc. to treat rubber production wastewater. These methods are not perfect, both The organic matter in the wastewater cannot be used as a resource, nor can the wastewater meet the national discharge stan...
