The invention relates to a method for recycling dibasic acid byproducts from adipic acid waste liquor, which comprises steps as follows: dibasic acid waste liquor is preheated by a preheater and enters a climbing film evaporator; the concentrated solution from the climbing film evaporator naturally flows to a falling film evaporator; the discharged material from the bottom of the falling film evaporator is in a molten state; after a seal tank is subjected to vacuum isolation, a safe evaporating tank is operated under normal pressure; and the liquor naturally flows to the safe evaporating tank to be buffered, and enters a flaker to form flakes, thereby obtaining the dibasic acid flake byproducts. Compared with the prior art, the invention enhances the evaporization efficiency, lowers the steam consumption, implements continuous operation of evaporative concentration of adipic acid waste liquor, implements continuous discharge to avoid the possibility of explosion due to overpressure of equipment, ensures the discharge requirement for water content and the stable operation of the flaker, can adapt to great incoming material fluctuation or steam pipe network fluctuation, reasonably utilizes the energy, and lowers the comprehensive energy consumption of the products.

The invention discloses a sewage treatment method capable of adjusting nitrogen and phosphorus removal capacity, belonging to the field of sewage treatment. The sewage of the present invention passes through the reaction tank and the secondary sedimentation tank in turn to realize enhanced nitrogen and phosphorus removal. When the operation mode beyond sludge is adopted, the total phosphorus removal rate is >90% or the effluent TP<1mg / L, ΔBOD / ΔTN<4, within the system The maximum flow flux in each area does not exceed 2.2Q, and the phosphorus content of the sludge in the return sludge is >4%. It has high-efficiency nitrogen and phosphorus removal, energy-saving and low-carbon operation, high load, and less land occupation. It can realize denitrification and phosphorus removal and TN removal. The efficiency is not limited by the reflux ratio, the control is simple, the operation and management are convenient, etc. The system of the present invention is composed of a reaction tank, a secondary settling tank and connecting pipelines. The reaction tank is sequentially composed of a pre-anoxic zone, an anaerobic zone, a middle sink zone, an aerobic nitrification zone, a denitrification zone, Aerobic decarbonization area, water outlet area, connecting pipelines include main water inlet pipe, branch water inlet pipe, water outlet pipe, sludge overflow pipe, sludge return pipe, excess sludge discharge pipe, etc., the process flow is simple.

The invention discloses a rapid starting method of an efficient autotrophic nitrogen removal system used for treating high-ammonia nitrogen wastewater, and belongs to the technical field of wastewaterbiological nitrogen removal. The problems are solved that in the prior art, a related system needs to occupy a large land, the inoculation amount is too large, starting time is long, the nitrogen removal load is low, impact resistance is poor, and the system is easily affected by water-entering organic matter. Pure film denitrificaiton is combined with mud film one-part form autotrophic nitrogenremoval, a denitrification pond is arranged in the front, an autotrophic nitrogen removal pond is arranged in the rear, and outgoing water returns. Three operation modes of the rapid starting method can be realized and include the parallel operation mode, the double-series A operation mode and the double-series B operation mode, the water outlet direction of four reaction ponds is controlled through a communication valve, and therefore the reaction ponds are connected in series or in parallel or operate independently; by means of inoculation, fed-batch and others, rapid starting of the technology is realized; according to treatment requirements, different technological arrangement modes are realized. The rapid starting method has the advantages that occupied land is small, the inoculationproportion is small, starting is rapid, the nitrogen removal load is high, the impact resistance is high, and resistance to water-entering organic matter is good.

The present application discloses a method, device, medium and equipment for controlling the output power of a dual internal-combustion unit. The method includes: judging whether the target output power required by the target dual internal-combustion unit is greater than the rated output power of a single internal-combustion unit in the target dual internal-combustion unit ; If so, then run the first internal combustion group and the second internal combustion group; the three-phase alternating current output by the first internal combustion group and the second internal combustion group is converted into the first direct current and the second direct current; the voltage of the first direct current and the second direct current Adjust the value to be consistent; when the first internal combustion set and the second internal combustion set realize DC grid connection, adjust the three-phase alternating current output by the first internal combustion set and the second internal combustion set, so that the first internal combustion set and the second internal combustion set The sum of the output power output is the target power. It can be seen that through this method, the respective output powers of the first internal combustion unit and the second internal combustion unit of the dual internal combustion units can be flexibly adjusted.
