Problems solved by technology

[0004] However, the core factor of activated sludge technology, activated sludge needs to be in the working state for a long time to maintain its own activity. Once the working state is interrupted, it is easy to cause the activated sludge to grow rapidly and cause its own activity to decline, which affects the sewage treatment effect, and even because of The interruption of nutrient supply causes a large number of microorganisms in the activated sludge to die, and also affects the sewage treatment effect of the activated sludge.

Embodiment 1

[0037] see Figure 1-6 A sustainable use of microbial attachment piles for coal chemical wastewater treatment pools, comprising a microbial attachment pile main body 1, a filling cavity is excavated in the microbial attachment pile main body 1, and a partition ring is fixedly connected to the inner wall of the filling cavity to fill the space in the cavity With the partition ring as the boundary, it is divided into three parts: supplementary cavity 2, exchange channel 3, waste material area 4 and fixed cavity 6. The supplementary cavity 2 and waste material area 4 are respectively located on the upper and lower sides of the exchange channel 3 and the floating ball 5. The exchange channel 3 communicates with the supplementary chamber 2 and the waste area 4, the fixed chamber 6 is located outside the floating ball 5, and the separated ring is fixedly connected with an exchange semi-permeable membrane 7 matching itself, and the exchange semi-permeable membrane 7 is located in the ...

Abstract

The invention discloses a sustainable microbial attachment pile for a coal chemical wastewater treatment pond, and belongs to the field of coal chemical wastewater treatment. According to the sustainable microbial attachment pile for the coal chemical wastewater treatment pond, in the normal working process of the scheme, microbial colonies stored in a fixation cavity absorb a nutrient solution to grow, along with the increase of the volume of the microbial colonies, the microbial colonies penetrate through permeation holes, grow to the outer side of a microbial attachment pile main body and grow into larger-volume microbial colonies, and under the impact of sewage, the microbial colonies located on the outer side of the microbial attachment pile main body are flushed into the sewage for sewage treatment. When sewage treatment is stopped, microbial colonies in the fixation cavity and a microorganism growth cavity are in a closed environment, most of the microbial colonies can fall into a dormancy period, the activity of microbial communities for sewage treatment can be kept for a long time, and the situation that the activity of sewage treatment microorganisms is reduced due to long-time work interruption is avoided.

Description

technical field [0001] The invention relates to the field of coal chemical wastewater treatment, more specifically, relates to a sustainable microbial attachment pile for a coal chemical wastewater treatment pool. Background technique [0002] Coal chemical industry refers to the process of using coal as raw material and converting coal into gas, liquid and solid fuels and chemicals through chemical processing. It mainly includes coal gasification, liquefaction, dry distillation, tar processing and calcium carbide acetylene chemical industry. Coal Chemical Processing Process. The chemical structure of organic matter in coal is a macromolecular structure with aromatic-based condensed rings as the unit core, interconnected by bridges, and various functional groups. Through thermal processing and catalytic processing, coal can be converted into various fuels and chemicals. [0003] The wastewater produced by coal chemical industry includes a large amount of aromatic hydrocar...
