Problems solved by technology

With people's emphasis on environmental governance, the treatment technology of phenol-containing industrial wastewater has not been developed and innovated, mainly physical methods, chemical methods and biological methods, and have achieved certain results in practical applications, but still There are many problems, mainly because the current technology is difficult to ensure the treatment efficiency and effluent quality of high-concentration phenol wastewater
[0003] Compared with physical and chemical phenol removal technologies, biological phenol removal technology is highly valued due to its low cost and no secondary pollution. However, due to the strong biological toxicity of phenol, it is difficult to achieve technical breakthroughs in biological technology Improving the phenol treatment capacity of wastewater

specific Embodiment approach

[0013] The bioaugmentation treatment method of phenol-containing wastewater of the present invention, its preferred embodiment is:

[0014] include:

[0015] Phenol-containing industrial wastewater is pretreated by front-end adjustment, air flotation or hydrolysis and acidification, and then enters the biological treatment pool. The biological treatment pool adopts the traditional A / O process or A 2 / O process structure, on the basis of maintaining the original process function, the A / O process or A 2 The O section of the / O process is divided into two or more sections, and the modified special biological treatment filler is added in the first section or the first few sections, and the obligate phenol is added in the latter section or the last few sections. Modified carrier of bacteria.

[0016] The special biological treatment filler uses a modified hydroxyl polymer hydrophilic polymer material as the growth carrier medium of the microbial flora. The special biological trea...

specific Embodiment

[0027] like figure 1 As shown, the method is as follows:

[0028] Phenol-containing industrial wastewater enters the method system after front-end pretreatment, and the system consists of traditional A / O process or A 2 / O process structure composed of 5, the wastewater is treated in the A pool and enters the O pool for biological enhancement treatment; the O pool is divided into two or more sections according to the engineering needs, and the modified special biological treatment filler 2 is added in the front section. Under the action of the device 1, it is in a uniform fluidized state in the pool, and together with the activated sludge, it undertakes the function of degrading organic matter in the wastewater; due to the special treatment of the filler 2, it has a better adsorption effect on the phenolic bacteria group. With the increase of time, a large number of phenolic bacteria are enriched on the surface of filler 2, thereby staying in the biological treatment tank for ...

Abstract

The invention discloses a biologically enhanced processing method of phenol containing wastewater. According to the method, phenol containing industrial wastewater is subjected to front end regulation, floatation or hydrolysis acidification pretreatment; then the wastewater is introduced into a biological processing tank, the biological processing tank adopts a conventional A / O technology or a A2 / O technology structure; on the basis that the processing functions of original technology are not changed, the O section of the A / O technology or A2 / O technology is divided into two or more sections; a dedicated biologically processed filling material, which has been modified, is added in the first section or front sections, and a modified carrier, where dedicated phenol-degrading bacteria are embedded, is added into the rear section or rear sections. The provided method can effectively process phenol containing wastewater through a biological mode. The phenol content of processed industrial wastewater is reduced to a low level, and thus processing difficulty and load of subsequent deep processing units are both reduced. The processing efficiency and discharged water quality of industrial wastewater in the whole system are improved. The qualified discharging and processing of wastewater are achieved.

Description

technical field [0001] The invention relates to an industrial wastewater treatment technology, in particular to a biointensified treatment method for phenol-containing wastewater. In particular, the waste water treatment method combining the embedding carrier process and the activated sludge process belongs to the field of environmental protection waste water treatment. Background technique [0002] Phenol-containing wastewater mainly comes from coking, oil refining, gas and other industries. Its quantity is large and harmful, so it has become a problem that cannot be ignored in industrial wastewater treatment and environmental protection. Phenolic compounds are protoplasmic poisons with strong biological toxicity, among which phenolic substances are one of the important components in phenolic substances. With people's emphasis on environmental governance, the treatment technology of phenol-containing industrial wastewater has not been developed and innovated, mainly physic...
