Processing technique for treating rubber block processing wastewater of rubber latex processing plant

Abstract

The invention discloses a processing technique for treating rubber block processing wastewater of a rubber latex processing plant, which comprises the following steps of: treating rubber latex solidified waste solution and rubber block processing wastewater, and establishing a plurality of continuous sedimentation filter tanks according to the discharge of the rubber block processing wastewater; before the rubber latex processing plant starts operating every year, cleaning the filter tanks, and fully filling the filter materials such as bagasse and the like into the plurality of continuous sedimentation filter tanks according to the volumes of the filter tanks; according to the condition of the final outlet wastewater of the filter tanks, the number of the filter tanks and the annual rubber latex processing time, gradually exchanging the bagasse or coconut fibers or banana cauloids in the filter tanks from the filter tank of the most front end, so that the filter capacity of the filter fermentation system is kept in dynamic balance and update; and preparing microbial culture mother solution containing probiotics such as yeast, lactic acid bacteria, bacillus licheniformis and the like, mixing, piling and fermenting the microbial culture mother solution, a sugar source, phosphate rock powder and the exchanged filter materials, and properly drying the fermented product to form a solid biological fertilizer. Generally, the method is simple, low in implementation and maintenance costs and the like.

Description

1. Technical field [0001] The invention relates to a processing technology for treating rubber block processing wastewater in a rubber latex processing plant. 2. Background technology [0002] In rubber latex processing plants, there are two main sources of waste water, one is rubber latex coagulation waste liquid, especially rubber concentrated latex whey coagulation waste liquid, and the other is rubber block extrusion and washing produced during rubber block processing , Waste water generated during the granulation process. Rubber coagulation waste liquid and rubber block extrusion waste liquid contain a lot of nutrients, which can be directly collected and fermented to produce bio-fertilizers. However, a large amount of waste water generated during the rubber block washing and granulation process, these rubber mixed processing waste water, nitrogen, phosphorus, potassium and other plant-available nutrient elements are low, the value of direct fermentation is not high, a...

AI Technical Summary

Problems solved by technology

However, a large amount of waste water is produced during the rubber block washing and granulation process. These rubber mixed processing waste water contain low levels of plant-available nutrients such as nitrogen, phosphorus, and potassium, and the direct fermentation value is not high. The amount of processing waste water is large. Difficult, usually discharged on site, causing water and environmental pollution around the processing plant

The traditional treatment of rubber processing waste water mixes rubber coagulation waste liquid and rubber block processing waste water. The amount of sewage is large, the pollution is serious, and the treatment is difficult.

So far, there is no proper treatment method for rubber processing wastewater
