Normal temperature and pressure working conditions, low-voltage direct current, no acid-base pre-regulation, no chemical hazardous waste sludge, low energy consumption; Biodegradability of wastewater improved after treatment , partial neutralization of acid and alkali, partial reduction of salinity, partial reduction of COD dry weight; replacing traditional three-effect evaporation, Fenton oxidation, iron carbon oxidation, etc.
Normal temperature and pressure conditions, extremely low energy consumption, high-purity products such as ammonium sulfate or ammonium chloride with strong anti-pollution properties recycled from ammonia nitrogen in wastewater, normal operation under high hardness and high suspended solids; replacing traditional Desalination, steam ammonia, crystallization of magnesium ammonium phosphate, chlorination breakpoint, etc.
Combination of intermittent oxygenation and continuous oxygenation, combination of falling aeration and forced aeration, rapid start of engineering bacteria, assembly design of process elements, simultaneous nitrification and denitrification, energy consumption and land occupation less than traditional A2O, SBR, etc. Particularly applicable in System reconstruction and expansion and limited site.
Diffusion dialysis is used to recycle residual impurity acids in wastewater. High-concentration heavy metals are recycled by ion exchange. The complex state of heavy metals is electrolyzed. Up-to-standard emissions of heavy metal with minimal solid waste is achieved by higher efficient heavy metal capture agents and reduction of limes and coagulant.
According to the sludge yield in different organic matter load conditions of the activated sludge process and biofilm process , the biochemical Residual sludge and coagulated chemical sludge generated in the water treatment process are minimized by making full use of the microbial hydrolysis process and hydrogen production and acetic acid process and anaerobic methanogenesis process.
Based on the vibrating membrane equipment, further concentration and reuse of the waste liquid or the reduction of its outbound disposal are to reduce the risks and costs of hazardous waste disposal. The anti-pollution performance is far superior to conventional processes such as ultrafiltration, and can be matched with other process for purification and reuse of produced water.
Atmospheric equipment which can be skid-mounted and mobile-processed is to convert biochemical sludge with higher water content after mechanical dehydration into biomass fuel with ultra-low water content and high burning value. There is no any harmful substance added or generated in the treatment process.
According to the distribution of ion types in salty wastewater, the optimal combination is made from high-density sedimentation, multi-media filtration, ion exchange, ultrafiltration, nanofiltration, reverse osmosis, high pressure reverse osmosis, and dish membrane. The investment and operation costs of the subsequent evaporation and crystallization section are reducted by liquid phase concentration.
No additional civil construction is required on the basis of conventional biochemical and coagulation treatment. It is directly transformed based original constration. The discharge is directly upgraded from the indirect discharge standard to the direct discharge standard.
The combination of cleaning technology and microbial repair technology can achieve the goals of oil recovery and site purification for tank bottom sludge, floor sludge, mud drill cuttings, oily soil, etc.
Ozone catalysis and electrolytic catalysis is used to further decompose the residual organic matter and improve the B / C ratio of it, an An improved biofilm method is followed to lower the concentration of COD and nitrogen and phosphorus pollutants under high hydraulic load and low organic load to meet increasingly stringent emission standards.
The engineering measure is used in homogenization and stabilization of the influent salinity, the combination of the salt-resistant engineering bacteria and microbial activation technology, a nutrient-based suspended bed and trapped contact fillers, rapid inoculation, proliferation and stabilization of microorganisms, which solves the problem of low and stable biochemical efficiency and low stability caused by medium and high salinity.
