We have solved the problem of sewage treatment for many chemical enterprises and successfully achieved standard discharge or reuse, and have been rated as a pioneer in Shandong's sewage treatment industry by some environmental protection departments. Especially in the treatment of pharmaceutical intermediate wastewater, cotton protein wastewater, refined cotton wastewater, cotton protein wastewater, PVC wastewater, as well as the treatment and reuse of black liquor wastewater and starch wastewater from paper mills, it has reached a relatively high level in China.

IC anaerobic reactor is a new type of anaerobic reactor after UASB and EGSB. It divides the reactor into upper and lower chambers through two layers of gas collection hoods, and the two chambers are combined together through an internal circulation device. Most of the organic matter entering the IC anaerobic reactor is digested in the lower reaction chamber, and the generated biogas is blocked and collected by the lower gas collection hood into the riser. Due to the density difference between the liquid inside and outside the riser, the fermentation liquid is continuously lifted to the gas-liquid separator. After separating the biogas, it flows back to the lower reaction chamber, forming a continuous cycle of fermentation liquid. Considering that the internal circulation occurs in the lower reaction chamber, the lower reaction chamber has a high hydraulic load. The high hydraulic load and high-yield gas load fully mix the sludge with organic matter, leaving the sludge in a fully expanded state. The high mass transfer rate greatly improves the anaerobic digestion rate and organic load. The upper reaction chamber is the low load area of the reactor, which only digests a small amount of organic matter that cannot be digested in time in the lower reaction chamber, resulting in low biogas production. The gas production load is low, and the internal circulation does not enter the upper reaction chamber. The lower gas production load and lower hydraulic load in the upper reaction chamber are conducive to sludge sedimentation and retention, thereby maintaining a higher sludge concentration in the reactor. Due to the fact that anaerobic digestion rate depends on sludge concentration and mass transfer rate, the factors affecting mass transfer are gas production load and hydraulic load. They are important factors for enhancing mass transfer and are also the fundamental cause of sludge loss. The IC anaerobic reactor, with its internal circulation device, changes the direction of gas production load and hydraulic load, which can avoid sludge loss under high loads, To some extent, the separation of high load and sludge loss has been achieved, which enables the IC anaerobic reactor to have higher organic load than UASB and EGSB.
1. Has a high volumetric loading rate. The IC anaerobic reactor has strong internal circulation, good mass transfer efficiency, and large biomass. Its water inlet load rate is much higher than that of ordinary UASB reactors, generally about three times higher. When treating high concentration organic wastewater with COD ranging from 10000-15000MG/1, the volumetric loading rate can reach 15-30KGCOD/M3?.
2. Strong resistance to shock loads. Due to the IC reactor achieving its own internal circulation, the circulation volume can reach 10-20 times that of the inlet water. Because the circulating water and influent are fully mixed at the bottom of the reactor, the concentration of organic matter at the bottom of the reactor is reduced, thereby improving the impact load resistance of the reactor. At the same time, the large amount of water also allows the bottom sludge to expand, ensuring full contact reaction between organic matter and microorganisms in the wastewater, and increasing the treatment load.
3. Good water stability performance. Because the IC reactor operates in series with the upper and lower UASB reactors, the lower reactor has a high organic loading rate and plays a rough treatment role, while the upper reactor has a low load and plays a fine treatment role, resulting in good and stable effluent quality.
