Problems solved by technology

The method of the present invention has wide applicability to various types of industrial high-phenol-containing wastewater, and the constructed functional flora overcomes the shortcomings of the above-mentioned single strains and exogenous strains, and the construction of functional flora has never deviated from the water quality of the original system The environment and the composition of the flora change dynamically, with strong adaptability. After adding, it can take effect quickly and be stable and long-lasting. It does not need to be continuously added for a long time. It is suitable for the recovery of abnormal states of biochemical systems, improving system processing efficiency and quick start after shutdown

Embodiment 1

[0057] Example 1 Sewage treatment plant A of a petrochemical company 2 / O system abnormal state repair project

[0058] At the beginning of 2014, due to the decline of crude oil quality, the phenol content of the sewage generated by the company increased sharply. A 2 The influent phenol content of the / O system reached 400-500mg / L, and the aerobic pool was strongly impacted. The activated sludge foam is serious, and the system is on the verge of collapse. The substandard treatment of the biochemical system seriously affects the subsequent treatment process. The only way to maintain the final effluent discharge is to meet the standard by limiting the influent flow. In order to repair the abnormal state of the system, the company once spent more than 500,000 yuan to purchase an imported bacterial agent. After adding and running for 3 months, the effect is acceptable but extremely unstable. Once the adding is stopped, the effluent will deteriorate, and the operating cost will co...

Embodiment 2

[0070] Example 2 Pilot test for increasing the treatment capacity of a coking company's sewage treatment plant

[0071] The company's early production scale was small, and the water flow rate of the biochemical system was always controlled at a low level, which did not reach the design flow rate, and the operation was in good condition. However, due to the expansion of production scale, it is planned to increase the system processing capacity in the near future. The company first utilized its 120m 3 A pilot test is carried out in the small aeration tank, and a rectification plan is formulated according to the situation of the pilot test. Without taking any measures, the influent flow rate was directly increased to 1.5 times the original flow rate. After 7 days, the volatile phenols in the effluent water began to increase, and increased to 150mg / L within 5 days. The pilot test failed. Adopt method provided by the invention to carry out pilot test subsequently, concrete implem...

Abstract

The invention belongs to the technical field of biochemical environmental protection and provides a method used for building functional florae by utilizing indigenous microorganisms and used for performing intensified treatment on industrial high phenol-content wastewater. The method mainly comprises the following steps: (1) sampling; (2) building the functional florae; (3) adding the functional florae into operation, and further establishing a complete set of integrated process of culture-use of the functional florae to realize the up-to-standard discharge of the phenolic wastewater. The method provided by the invention has wide applicability on various industrial high phenol-content wastewater; the building of the functional florae never separate from the water quality environment of an original system; the florae dynamically change in composition, are high in adaptability, can work fast after being added and has a stable and lasting effect, does not need to be added continuously for a long time, and is suitable for recovering the abnormal condition of a biochemical system, improving the treatment efficiency of the system and rapidly starting the system after shutdown. The method provided by the invention has a reasonable process, is low in cost, easy to popularize and implement and has good environmental benefits, economic benefits and social benefits.

Description

technical field [0001] The invention belongs to the technical field of biochemistry and environmental protection, and provides a method for constructing functional flora by using indigenous microorganisms and used for intensive treatment of industrial waste water with high phenol content. Background technique [0002] With the rapid development of petrochemical, coking, resin and other industries, the production of various industrial phenolic wastewater has also increased accordingly. Phenolic compounds are a class of toxic substances that are toxic to almost all organisms. Therefore, the treatment of industrial high-phenolic wastewater is urgent. At present, the treatment methods of phenolic wastewater mainly include solvent extraction, chemical oxidation, chemical precipitation and biochemical treatment. Among them, the biochemical method is economical, efficient, thorough, and has no secondary pollution, and has become the focus of research on the treatment of phenolic w...
