Embodiment 1

[0027] In order to make the present invention clearer, a high-concentration organic wastewater treatment device of the present invention will be further described below in conjunction with the accompanying drawings. The specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] Such as figure 1 Shown, a kind of high-concentration organic waste water treatment device comprises dilution tank 1, is characterized in that:

[0029] The dilution tank 1 is connected to a carbon washing tower 2 through the first water inlet pipe 17, and the top of the carbon washing tower 2 is provided with a group of spray pipes 7 connected to the first water inlet pipe 17, facing the carbon washing tower below the spray pipe 7. Tower 2 both sides are provided with a pair of powder blowing device 8, and powder blowing device 8 comprises a pulverized coal bin 8b that is connected on the side wall of carbon washing tower 2 and a blow...

Abstract

The invention relates to a high-concentration organic wastewater treatment device, which comprises a dilution tank (1), a carbon washing tower (2), an oxidation tower (3), a secondary carbon washing tower (4) and a resin adsorption tank (5) which are connected in sequence, and a spray pipe (7), a powder blowing device (8), a vibration plate (9) and a sieve plate (10) are arranged in the carbon washing tower (2); an oxidation liquid sprayer (11) and a rotary spray pipe (12) are arranged in the oxidation tower (3), one end of a rotary spray pipe (12) is connected with a rotary motor (13), and agroup of spray openings (14) are formed in the rotary spray pipe (12); a water distribution pipe (15) and a pulverized coal adsorption plate (16) are arranged in the secondary carbon washing tower (4), and a water outlet (5a) is formed in the bottom of the resin adsorption tank (5). The method has the advantages that the traditional activated carbon can be replaced to purify the wastewater, the cost is reduced, the wastewater is purer after layer-by-layer filtration and contact reaction, the peculiar smell is eliminated, and the treatment effect is improved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment equipment, in particular to a high-concentration organic wastewater treatment device. Background technique [0002] High concentration organic wastewater mainly has the following characteristics: [0003] (1) High concentration of organic matter: COD is generally above 2000mg / L, some even as high as tens of thousands or even hundreds of thousands. Relatively speaking, BOD is relatively low, and the ratio of BOD to COD in many wastewaters is less than 0.3; [0004] (2) The composition is complex: the organic substances in toxic wastewater are mostly aromatic compounds and heterocyclic compounds, and also contain sulfides, nitrides, heavy metals and toxic organic substances; [0005] (3) High chroma and peculiar smell: some wastewater emits a pungent stench, which has adverse effects on the surrounding environment; [0006] (4) It has strong acid and strong alkali, which will make the...
