Embodiment Construction

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like figure 1 As shown, the crushed lime enters the mixing and stirring box from the lime feed pipe 8, and the low-temperature acidic waste water enters the waste water inlet pipe 9, and is divided into two parts after entering. With the water tank 1, the lime entering the mixing and stirring tank from the lime feed pipe 8 and the waste water stirring paddle are mixed and reacted under the stirring, and the heat generated by the dissolution of the lime is transferred from the wall of the mixing and stirring tank 2 to the outside of the box to neutralize the waste water in the water tank. ; After the lime in the mixing tank 2 and the acid waste water are stirred and reacted, the lime sediment sinks to the bottom of the tank and is discharged through the sedimentation discharge pipe 4. At this time, lime water with a certain temperature is in the mixing tank 2, and...

Abstract

The invention discloses a device for synchronously neutralizing and heating low-temperature acidic waste water, which comprises a neutralization water tank (1), a waste water inlet pipe (9) and a waste water outlet pipe (7), a mixed stirring tank (2) which takes a tank body as a heat conduction material is provided in the neutralization water tank (1); a stirring paddle (3) is provided in the mixed stirring tank (2), a communicating pipe (5) which is communicated with the neutralization water tank (1) is provided at the upper part of the mixed stirring tank (2), a non return valve (6) is provided in the communicating pipe (5), a lime inlet pipe (8) is provided at the upper part of the mixed stirring tank (2), a deposition drain tube (4) is provided at the bottom of the mixed stirring tank (2), the waste water inlet pipe (9) is respectively communicated with the neutralization water tank (1) and the mixed stirring tank (2); the waste water outlet pipe (7) is arranged on the upper part of the neutralization water tank (1). According to the invention, waste water can be heated by using waste heat to achieve the purposes of treating waste by waste and energy saving as well as consumption reduction.

Description

1. Technical field [0001] The invention relates to a wastewater treatment equipment, in particular to a synchronous neutralization heating device for low-temperature acidic wastewater. 2. Background technology [0002] At present, the vast majority of sewage treatment in my country is treated by biochemical methods. In biochemical wastewater treatment, according to the influence of temperature on the growth and metabolism of microorganisms, low-temperature wastewater is generally considered to refer to wastewater with a temperature below 10 °C. Because the viscosity of sewage increases at low temperature, the diffusion and sedimentation of organic matter in sewage is slow, which is easy to cause sludge expansion or a large amount of activated sludge to be lost, and the effluent SS is high; Serious acidification and low methane yield; low temperature can also significantly reduce the activity, quantity and population distribution of microorganisms in activated sludge, weaken...
