Problems solved by technology
[0007] The purpose of the present invention is to provide a safe operation system for sewage treatment impacted by soybean product industrial wastewater, which has the advantages of simple structure and relatively low cost, and solves the problem that the existing sewage pretreatment equipment is not easy to remove when filtering the wastewater. The waste residue and impurities on the filter screen can easily cause the filter screen to be clogged and affect the efficiency of sewage treatment.

The invention discloses a bean product industrial wastewater impacted sewage treatment safe operation system. The technical scheme includes the steps of: 1) according to the water quality condition ofbean product industrial wastewater and the different effects of impact time, impact water volume and impact water quality on an urban sewage treatment system, looking for a matching coagulant for treatment; 2) employing a composite coagulant to study the coagulation condition of coagulants with different proportions in bean product wastewater, and selecting a coagulant proportion with an optimalcoagulation effect according to the experimental result; 3) studying the coagulation condition of bean product wastewater under different coagulant dosages; and 4) studying the safe operation mode ofthe urban sewage treatment system under an impact load. The bean product industrial wastewater impacted sewage treatment safe operation system provided by the invention is connected to the urban sewage treatment system through innovation points of the whole system and device, and has the advantages of simple structure, low cost, good filtering effect and easy disposal of waste residue impurities on the filter net.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment safe operation system impacted by bean product industrial wastewater. Background technique [0002] The wastewater from soybean product processing plants mainly comes from soaking, soaking, pressing and washing wastewater of raw soybeans. The wastewater has high organic content and strong biochemical properties, and is a high-concentration wastewater that pollutes the environment. Before discharging these wastewaters, the suspended solids and scum in the wastewater need to be treated. [0003] The existing sewage pretreatment equipment has a complex structure and is expensive. Many series of bean product processing plants are very small in scale and cannot afford to purchase working wastewater treatment equipment. They will usually be discharged secretly, causing damage to the urban environment. pollution, and the existing sewage pretreatment equipmen...
