Description
Technical field
The invention belongs to the biochemical treatment of industrial wastewater technical field, be specifically related to a kind of multifunctional composite biological nutrient for industrial wastewater biochemical treatment.
Background technology
Serious at water resource pollution and water demand increases day by day today, the importance of sewage purification also increases day by day, and the processing of industrial and agricultural wastewater and sanitary sewage is subjected to extensive concern, and people work out various water treatment method in succession.In various sewage disposal technologies, especially the biochemical processing process of sewage, the processing methodes that adopt based on activated sludge process, its principal feature are that the living microorganism in the active sludge intermixture that utilizes in the bio-reactor is degraded to the intravital pollutent of water and reached the purpose of removal pollutent more.But, for trade effluent, lacking in it as the more complete nutritive element that is suitable for microorganism growth of sanitary sewage, many employing microorganisms " domestication " make the microorganism in the active sludge adapt to waste water quality usually.And for the trade effluent of difficult degradation, especially petrochemical complex class industrial production waste water, even by the main component of taming its active sludge is bacterium and algae, common protozoon and metazoan exist hardly, cause trade effluent to be difficult to reach the requirement of sewage drainage standard, often need to increase follow-up advanced treatment facility in the biochemical treatment stage.Industrial production waste water is because water quality and quantity changes greatly, and there are some sudden accidents such as the unexpected rising of pH value in regular meeting or reduce simultaneously, and difficult degradation or toxic substance exceed standard and all can cause the biochemical treatment system paralysis, thereby cause the delay of production.Therefore, be badly in need of a kind of biological nutrient that ensures the normal operation of biochemical treatment of industrial wastewater system, in the hope of shortening the activated sludge acclimatization cycle, Industrial Wastewater Treatment is started fast, make the fast quick-recovery of system when preventing to cause the biological treatment system abnormal running because of the variation of trade effluent water quality and quantity or sudden accident.
Seen known biological nutritive agent, mainly as vegetable fertilizer and animal-feed to soil improve (Xu Chunzhou. poly effective biological nutritive agent [P] .CN1377860), perhaps for the nutrition agent that promotes certain material to degrade fast (Zhang Yingpeng etc. a kind of nutrition agent that promotes the quick decomposition of stalk and preparation method thereof and use [P] .CN101225002), for biological wastewater treatment, someone reported a kind of bacterium composite nutrient, this bacterium composite nutrient is mainly used in the bacterium in the fast culture sanitary wastewater treatment system, make it in the short period of time, make required bacterial species of the normal operation of sanitary wastewater treatment system and quantity (Liu Yingxu etc. a kind of bacterium composite nutrient [P] .CN1966672).And solve the biological domestication fast of biochemical treatment of industrial wastewater and multifunctional composite biological nutrient and the compound method thereof that the fast quick-recovery of system is used, then do not appear in the newspapers.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, providing a kind of can shorten the activated sludge acclimatization cycle, industrial wastewater treatment system is started fast, can make the multifunctional composite biological nutrient for industrial wastewater biochemical treatment of the fast quick-recovery of biochemical treatment system as buffer reagent and nutritive substance when variation of trade effluent water quality and quantity or sudden accident again.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of multifunctional composite biological nutrient for industrial wastewater biochemical treatment, it is characterized in that, and form by following raw materials by weight percent:
