[0014] (III) Beneficial Effects

[0015] This invention provides a modular treatment device for efficiently treating high-concentration organic wastewater, which has the following advantages:

[0016] 1. This modular treatment device for high-concentration organic wastewater is designed with a sedimentation chamber, a filtration chamber, an aeration chamber, and aeration pipes. During operation, wastewater is introduced into the sedimentation chamber for settling. Coagulants and flocculants are added to coagulate and settle colloids and fine suspended solids in the wastewater. A sludge discharge pipe at the bottom allows for periodic sludge removal. The pre-treated wastewater is then transported to the filtration chamber on one side for further filtration, where residual suspended solids are effectively retained. The pre-purified wastewater flows into the aeration chamber through pipes. The aeration pipes have evenly distributed micropores on their surface. Connected to an external air pump, air is continuously supplied to the wastewater in the form of fine bubbles, promoting full contact between the wastewater and microorganisms, enhancing biodegradation. This multi-stage treatment works synergistically to significantly improve the treatment efficiency of high-concentration organic wastewater, ensuring that the effluent meets standards.

[0017] 2. This modular treatment device for high-concentration organic wastewater is designed with a stirring mechanism. During stirring, chemicals are added to the wastewater to accelerate flocculation. The drive motor rotates the stirring rod to ensure thorough mixing. Combined with the scrapers on both sides, impurities adhering to the inner wall can be scraped off, thus cleaning the inner wall of the sedimentation chamber and preventing impurities from accumulating on the inner wall, which would cause inconvenience for subsequent cleaning operations.
