Abstract

The invention relates to the technical field industrial water treatment and discloses a drilling wastewater treatment device. The drilling wastewater treatment device comprises a tank body and a device support, wherein the tank body is connected with the device support; a water inlet pipe is arranged at the lower end of the tank body; an exhaust pipe is connected with the upper end of the tank body; an aeration component used for conveying gas is arranged in the tank body; the aeration component is communicated with the outer side; upper and lower two water distribution plates are respectively arranged in the tank body; a plurality of water distribution holes are formed on the water distribution plates; a sludge adding pipe and a water draining pipe are connected with the upper end of the tank body. Compared with the prior art, the technical scheme has the advantages that the existing density of the microbial community is increased, the capacity of high load resistance of the fluidized bed is increased, the reaction between the microbial community and the pollutant is more sufficient, the physical form of the fluidized bed is more stable and the effect of aerobiotic treatment or anaerobic treatment is better.

Description

technical field [0001] The invention relates to the technical field of industrial water treatment. Background technique [0002] In oil and gas exploration, drilling and production operations, in order to ensure the normal operation of drilling operations and provide high-quality wellbores and stable well walls for later operations, a large number of high-color, high-pollution, and refractory polymers are used in drilling operations. mud system. However, a large amount of drilling fluid enters the drilling wastewater during use, causing the drilling wastewater to become industrial wastewater with high solid content, high chroma, high organic content, high heavy metal content, and high mineral oil content. This industrial wastewater has high concentration, Pollution, difficult to degrade characteristics. [0003] The hazards caused by the discharge of such industrial wastewater into the environment include: ①Wastewater flushed into rivers or infiltrated into formations will...
