Problems solved by technology

[0004] This method has huge system, huge investment, large floor area and high operating cost
The cost of electricity consumption is the main cost of sewage treatment, generally accounting for 70% of the cost of sewage treatment, and the cost is as high as tens of millions
There is secondary pollution in chlorine addition
Powerless for granular or dense substances, low treatment efficiency for slightly polluted water, garbage, leachate, printing and dyeing water decolorization, pharmaceutical sewage, etc., activated sludge causes secondary pollution, and the treatment cost is higher

Embodiment 1

[0031] The method and equipment for treating sewage by pyrolysis / combination combustion provided by the present invention include an outer cylinder 1 and an inner cylinder 2, and a sewage inner cavity 6 between the inner cylinder and the outer cylinder is separated by the cylinder. The plate 5 is divided into two chambers 7 and 8 communicating with each other. The difference between the outer diameter of the inner cylinder and the inner diameter of the outer cylinder is 8 centimeters. meters, and a cylinder with a diameter of 100 centimeters. The central fuel inlet of the dome 3 of the inner and outer cylinders is 5 centimeters in diameter, and the mixer 11 arranged above the fuel inlet is a commercially available general-purpose mixer, and the liquefied gas and air entering the mixer are first calculated by combustion chemical heat balance The amount, but generally adopt the stoichiometric air of about 1.2-1.3 times excess air.

[0032] First, the above-mentioned predetermin...

Abstract

The invention relates to a pyrolysis / combination combustion processing method for processing sewage water and the corresponding device, which comprises: getting the sewage water into a filter grid tank and a desilting tank to remove the floated or suspended substance, sand particles and other solid particles of the sewage water, mixing with 100-10000 ppm auxiliary agent, pyrolysis / combination combustion processing on the flame of high-temperature fuel in the temperature of 1800-2000 Deg. C in a pyrolysis / combination combustion processing device, then getting through a settling and filtering zone to reach the national primary emission standard and the germicidal ratio is 100%, the outlet hot water can be used in heating hot water or can be used in reclaiming heat by a heat exchanger.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a novel pyrolysis / combination combustion method and equipment for treating sewage. Background technique [0002] With the rapid development of industrial and agricultural production in various countries in the world, a large amount of domestic sewage and industrial sewage are produced accordingly. Due to the fact that sewage treatment technology lags behind the development of industrial and agricultural production, and the investment and operation costs of sewage treatment are huge, a large amount of industrial sewage and domestic sewage have not been produced. Discharge directly into rivers, lakes or the sea has caused a sharp deterioration in the quality of many rivers, lakes and coastal waters in the world, some of which have reached Grade IV or Grade V water quality, which not only seriously damages the balance of the ecological environment, but also exacerbates the shortage of...
