Abstract

The invention discloses a treatment device for high-concentration wastewater in the coal chemical industry, which comprises a purification box. A feed pipe is arranged in the middle of the upper end of the purification box. A stone filter layer and an activated carbon filter screen are arranged in the feed pipe sequentially from top to bottom. The purification box at the bottom of the filter layer is provided with a net pocket, and the water outlet on the lower right side of the purification box is connected to the liquid inlet pipe of the flocculation reaction device through a conduit, and a water pump is worn on the liquid inlet pipe. The invention has a simple and reasonable structure, guarantees the biochemical treatment effect, thereby reducing membrane fouling, low membrane cleaning frequency and long service life, and the MBR effluent is stable without suspended matter, which can ensure the deep treatment effect, and is also suitable for hydrolytic acidification. At the same time, the mixing of materials can be accelerated through the stirring frame, which greatly improves the hydrolysis efficiency and has strong practicability.

Description

technical field [0001] The invention relates to a wastewater treatment device, in particular to a high-concentration wastewater treatment device for coal chemical industry. Background technique [0002] Globally, coal is more plentiful and relatively cheap than oil and natural gas, and oil shortages are growing. Some coal-rich countries such as the United States, Australia, India, Germany, etc., are stepping up research or development of coal chemical projects. In recent years, my country has also researched and developed new coal chemical technology, established a number of coal chemical demonstration projects, and built the world's largest direct coal to oil project. However, for coal chemical projects in areas rich in coal resources but short of water resources, in the case of large water consumption and sewage discharge, there is an urgent need for a feasible high-concentration coal chemical wastewater treatment process to ensure the local economic and social benefits o...
