Synthetic rubber processing waste water treatment device and method

Abstract

The invention discloses a synthetic rubber processing waste water treatment device which comprises a water-collecting well, a grit chamber, a reaction tank, an air floatation tank, a grilling well, an adjusting tank, a hydrolysis tank, an A tank, an O tank, a secondary sedimentation tank, a clean water tank, a carbon filter canister, a drainage well and a sludge thickening tank. The water-collecting well is connected with a production waste water discharge port, an output end of the water-collecting well is connected to the grit chamber, an upper liquid output end and a lower sludge output end are arranged on the grit chamber, the lower sludge output end of the grit chamber is connected to the sludge thickening tank, the upper liquid output end of the grit chamber is connected to the reaction tank, the reaction tank is connected with the air floatation tank, an output end of the air floatation tank is connected to the adjusting tank, the grilling well is connected with domestic waste water output end, an output end of the grilling well is connected to the adjusting tank, and the adjusting tank is connected with a process waste water output end. Synthetic rubber processing waste water is treated by the aid of various processes in a united manner, discharged water can reach standards, waste materials can be turned into materials of value, and resources are comprehensively utilized.

Description

technical field [0001] The invention relates to the technical field of rubber processing wastewater treatment, in particular to a synthetic rubber processing wastewater treatment device and method. Background technique [0002] The composition of synthetic rubber wastewater is very complex, and it is difficult to biochemically degrade. It has the characteristics of high salt content and high chroma. Synthetic rubber wastewater mainly comes from the coagulation, washing and extrusion processes in the production of synthetic rubber. The discharge volume is large, the toxicity is strong, and the water quality is complex. Among them, the COD is 300-2000mg / L, and the BOD is 100-360mg / L. If it is discharged directly, it will be serious. pollute the ecological environment. With the increasingly stringent environmental protection regulations, the research on synthetic rubber wastewater treatment technology will become an important topic in the rubber industry. Several synthetic ru...

Problems solved by technology

5 Existing problems and development direction Synthetic rubber wastewater is a kind of wastewater that is difficult to treat. Using physical, chemical, or biological methods alone, the effect is not ideal, and the wastewater is difficult to discharge up to the standard

[0032] According to the above description, we can know that although the synthetic rubber processing wastewater treatment process has been developed to a relatively mature level, there are still many problems in the field of synthetic rubber processing wastewater treatment. If the emission reaches the standard, the existing process must be integrated, and a combination of multiple processes can be used to discharge the standard, and even turn waste into treasure to achieve the purpose of comprehensive utilization of resources.
