Abstract: The present disclosure providing an LED lamp with a heat sink and with a power supply received in a housing, includes the housing, a body, the power supply received in the housing, and a first connecting member arranged between the housing and the body. The body includes the heat sink, and a plurality of first LED plates installed on the heat sink and electrically connected to the power supply; the first connecting member including an upper portion clamped with the housing, and a lower portion fixed with the heat sink. The present disclosure provides the first connecting member to separate the power supply from the heat sink and increase a distance between the power supply and the heat sink to reduce heat transferred from the first LED plates to the power supply; the first connecting member is clamped with the housing, which is convenient for assembling the LED lamp.

Abstract: A method for processing fluoride-containing wastewaters from a factory, which includes the following steps: Step 1: collecting the fluoride-containing wastewaters into three pools: an acidic high-fluoride wastewater, an acidic low-fluoride wastewater, and an alkaline wastewater; Step 2: adding a calcium compound to the acidic low-fluoride wastewater to produce a calcium-containing solution; Step 3: reacting a portion of the calcium-containing solution with the acidic high-fluoride wastewater at a calcium-to-fluoride molar ratio of from about 0.5:1 to about 1.

Abstract: A method for effectively degrading and destroying many pharmaceutical and personal care compounds in aqueous solutions. The method includes providing an aqueous solution containing at least one pharmaceutical or personal care compound (e.g., estrogene hormone, antibiotics, and the like) to a reactor. A source of ultrasound is provided having a predetermined energy and intensity. The aqueous solution is sonicated in the reactor to degrade and destroy the at least one pharmaceutical or personal care compound. Further provided is a related method for degrading and destroying many pharmaceutical and personal care pollutants in aqueous sludge while simultaneously enhancing the biodegradability and dewaterability of the aqueous sludge. Still further provided is a related method for predicting the first order ultrasound-induced degradation rate constant of any estrogen compound present in an aqueous solution based on the rate constant of estrone.
