Because the current social water pollution is serious, and the conventional method cannot eff ectively manage alltypes of water pollution, and its single eff ect cannot be satisfactory, we must seek new and eff ective treatment. Thepaper is a comprehensive review of the best practices of the conventional wastewater treatment method with referenceto the experiments and research results of nanotechnology in sewage treatment. Comparison of nanotechnology canbe compared with conventional methods to make the particles have a special function, and some special performancejust in the sewage treatment medium to a good effect: the depth of the catalytic method can be effective in thedecomposition of many types of organic pollutants such as halogenated hydrocarbons Class, chlorinated phenols,cyanide, various organic acids and can handle metal particles; adsorption method for the water heavy metal pollutiontreatment costs less, simple and widely used, nanofi ltration membrane can replace the adsorption and electrochemicalmethods, Pulping and precipitation are one of the most eff ective methods for the treatment of colloidal wastewater. Itcan eff ectively reduce the turbidity and chroma of waste water, remove a variety of macromolecular organic matter andsome heavy metal ions ( Mercury and lead); organic / inorganic composite nanoparticles with its excellent inorganicmaterials, light, electricity, magnetic and other properties, organic materials, excellent processing performance,biocompatibility, for many diffi cult to deal with water pollution control, which has a corresponding method, can besimple and eff ective to solve the problem. The application of nanotechnology in water treatment has shown a broadprospect, but needs further research and improvement.

This study found a new type of immobilized mycelial pellet GX-1310, which can better treat industrial wastewater. Among them, Aspergillus fumigatus G-13 (degradable lignin) was combined with Bacillus cereus X10-1-2 (having the ability to produce cellulase), and the two synergistically produce strong degradation ability. Taking combined mycelial pellet as the research object, its ability to treat papermaking wastewater, heavy metal wastewater and dye wastewater was investigated. The combined mycelial pellet was superior to the single fungal mycelium in the degradation of lignocellulose, removal of heavy metal ions and adsorption capacity of dyes. And the combined mycelial pellet has a wide range of application conditions (temperature range 28-34°C and pH range 4-8), which can maintain high processing capacity for papermaking wastewater, heavy metal wastewater and dye wastewater. After three batches of wastewater treatment, the combined mycelial pellet still maintains high activity and can continuously treat wastewater. The study fixed the single fungal mycelium together with cellulose-degrading bacteria, the strains producing different enzymes were combined to form a multi-functional combined mycelial pellet. This method provides a new way for industrial wastewater treatment.
