The invention relates to the technical field of waste treatment and solidification, and discloses a fly ash slag and sludge synergistic stabilization treatment method which comprises the following steps: S1, raw material pretreatment: dehydrating fly ash by using a centrifugal dehydrator until the water content is lower than 10%, and treating the fly ash and slag by using a vibrating screen and a jaw crusher until the particle size is 0.5-2 mm; dehydrating the sludge until the water content is lower than 30% by using a belt filter press, and then drying the sludge in a hot air drying furnace until the water content is lower than 10%; s2, raw material mixing: mixing the pretreated fly ash, slag and sludge according to a set mass ratio; s3, adding a curing agent: adding the curing agent into the mixture, and uniformly stirring. By optimizing the proportion and selecting the proper curing agent, the problems of insufficient stability of a cured body and incomplete sealing of harmful substances are solved, and by treating the raw materials, adding the curing agent and optimizing the curing agent, the problems of poor sealing effect of heavy metals and high treatment cost are solved.

The invention relates to the technical field of fan variable-pitch systems, in particular to a method and a system for transforming a variable-pitch system of a sea-mounted fan, which comprises the following steps: analyzing the sea-mounted fan, obtaining the existing problem of the variable-pitch system, designing a transformation scheme of the variable-pitch system of the fan according to the existing problem, and transforming and debugging the variable-pitch system on site according to the transformation scheme and equipment transformation implementation conditions. The variable pitch system of the sea-mounted fan is improved, an original direct-current variable pitch motor of the fan is replaced with an alternating-current permanent magnet synchronous motor, and a super capacitor is used for replacing a lead-acid battery to serve as a back-up power source of the variable pitch system. The durability of the device is improved, and the work such as battery replacement and motor carbon brush cleaning which originally need frequent maintenance is reduced. The super capacitor has a longer life cycle, and the replacement frequency is reduced, so that the long-term maintenance cost and the spare part consumption cost are reduced.

The invention provides a water pump operation control method and system, an air conditioner water pump and an air conditioning unit. The water pump operation control method comprises the steps that when the water pump starts to be in an operation stopping state, the minimum value of the operation interval duration of the water pump is obtained, and timing is started; when the timing time reaches the minimum value, obtaining and identifying current electricity price information sent by the power grid; and adaptively adjusting the operation interval duration of the water pump according to the current electricity price information. According to the water pump operation control method, the technical problem that in the prior art, in the transition season or under the condition that the unit does not operate for a long time, dynamic changes of electricity price signals are not fully considered when the water system air conditioning unit starts the water pump regularly, and operation cost is possibly increased is effectively solved.
