Embodiment Construction

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

[0017] Such as figure 1 As shown, the crushed lime enters the mixing tank through the lime feed pipe 8, and the low-temperature acidic waste water enters through the waste water inlet pipe 9, and after entering, it is divided into two parts, one part of the waste water enters the mixing tank 2, and the other part of the waste water enters the medium With the water tank 1, the lime that enters the mixing tank through the lime feed pipe 8 and the mixing reaction of the wastewater stirring paddle, the heat generated by the dissolution of the lime is transferred from the tank wall of the mixing tank 2 to the outside of the tank and neutralizes the waste water in the tank ; After the lime in the mixing tank 2 is stirred and reacted with the acidic wastewater, the lime sediment sinks to the bottom of the tank and is discharged through the sediment discharge pipe 4 . Now, in...

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 waste water treatment equipment, in particular to a synchronous neutralization heating device for low-temperature acid waste water. 2. Background technology [0002] At present, most of the sewage treatment in our country is treated by biochemical method. In biochemical sewage treatment, according to the influence of temperature on the growth and metabolism of microorganisms, it is generally considered that low-temperature sewage refers to sewage with a temperature below 10 °C. As the viscosity of sewage increases at low temperature, the diffusion and sedimentation of organic matter in sewage are slow, which may easily lead to sludge swelling or a large loss of activated sludge, resulting in high effluent SS; low temperature will increase the amount of dissolved gas in sewage, which will easily lead to sludge floating, Severe acidification and low methane yield; low temperature can also significantly reduce the activity, qu...
