Reclaimed water pretreatment equipment for a new power plant

Abstract

The invention provides reclaimed water pretreatment equipment for a new power plant. The equipment comprises a mechanical acceleration clarification tank, and a water inlet main pipe is movably mounted on the outer surface of one side of the mechanical acceleration clarification tank; a pH regulating tank is arranged on the other side of the mechanical acceleration clarification tank; a first dosing bin is arranged in the middle of the outer surface of the upper end of the mechanical acceleration clarification tank; a variable-pore filter tank is arranged on one side, far away from the mechanical acceleration clarification tank, of the pH regulating tank; a clean water tank is arranged on one side, far away from the pH regulating tank, of the variable-pore filter tank; and communicating pipes are movably mounted among the mechanical acceleration clarification tank, the pH regulating tank, the variable-pore filter tank and the clean water tank. According to the reclaimed water pretreatment equipment for the new power plant, by adjusting the pH value of reclaimed water, supersaturated calcium carbonate is prevented from precipitating in the variable-pore filter tank, microorganisms are prevented from breeding on the surface of the filter tank, various agents in the clarification tank are mechanically accelerated to be independently added, agent mixing is avoided, the variable-pore filter tank filters uniformly, the filtering effect is improved, and meanwhile filtered impurities are convenient to clean.

Description

technical field [0001] The invention relates to the technical field of reclaimed water treatment, in particular to reclaimed water pretreatment equipment for a new power plant. Background technique [0002] With the rise of circular economy and green economy, reclaimed water discharged from urban sewage treatment plants can be used as replenishment water for power plant circulating water. When reclaimed water is used as the replenishment water source of recirculating water for power plants, in order to ensure long-term stable operation of the system, it is necessary to reduce the carbonic acid in the water. Salt hardness, to prevent power plant units from scaling under the operating conditions of high concentration ratio of circulating water, the reclaimed water advanced treatment process needs to be implemented, but the current reclaimed water treatment equipment has certain defects: 1. The reclaimed water is clarified in the mechanically accelerated clarifier After that, i...

[0002] With the rise of circular economy and green economy, reclaimed water discharged from urban sewage treatment plants can be used as replenishment water for power plant circulating water. When reclaimed water is used as the replenishment water source of recirculating water for power plants, in order to ensure long-term stable operation of the system, it is necessary to reduce the carbonic acid in the water. Salt hardness, to prevent power plant units from scaling under the operating conditions of high concentration ratio of circulating water, the reclaimed water advanced treatment process needs to be implemented, but the current reclaimed water treatment equipment has certain defects: 1. The reclaimed water is clarified in the mechanically accelerated clarifier After that, it directly enters the variable pore filter. Due to the high pH value of the clarified water, it is easy to produce supersaturated calcium carbonate and precipitate in the variable pore filter, and at the same time, it is easy to breed microorganisms at the bottom of the tank. The same dosing tube is used for dosing, because the wall of the dosing tube is wet, it is easy to adsorb various medicines on its surface, resulting in mixing of medicines, which affects the effect of dosing treatment. 3. The reclaimed water entering the variable pore filter is concentrated in A certain area of ​​the packing affects the filtering effect, and the impurities after the packing are filtered are not easy to clean
