Problems solved by technology

[0005] has a good removal effect on phenols and benzenes, but it can treat some refractory organic substances such as quinolines, indoles, pyridines, and carbazoles The effect is poor, making it difficult for the CODcr of the coal chemical industry to meet the first-level standard
At the same time, the coal chemical industry wastewater has the problem of high chroma and turbidity after being treated by the activated sludge method (due to the organic matter containing various chromophores and auxochromes, such as 3-methyl-1,3,6 heptatriene , 5-norbornene-2-carboxylic acid, 2-chloro-2-norbornene, 2-hydroxy-benzofuran, phenol, 1-methylsulfonyl-4-methylbenzene, 3-methylbenzo Thiophene, naphthalene-1,8-diamine, etc.)

Embodiment Construction

[0011] Refer to the attached figure 1 A biochemical treatment device for coal chemical wastewater invented will be described in detail below.

[0012] The present invention is mainly composed of regulating pool 1, biochemical pool 2, sedimentation pool 3, and discharge pool 4, which are connected in two phases through pipelines in turn; regulating pool 1 is provided with a water inlet pipe to flow into waste water, and discharge pool 4 is provided with a water outlet pipe to discharge treated water . The hydraulic retention time of the adjustment pool 1 is above 12h, and an underwater mixer is installed in the pool to mix the water quality to ensure sufficient mixing of the workshop drainage; the hydraulic retention time of the biochemical pool 2 is 60h-72h; the biological carrier is made of modified polyurethane as the main material The carrier has the characteristics of small specific gravity, large specific surface area, strong adsorption capacity, and good biocompati...

Abstract

The invention relates to a wastewater treatment device, in particular to a biochemical treatment device for wastewater from the coal chemical industry. The wastewater biochemical treatment device is mainly composed of a balancing tank, a biochemical tank, a sedimentation tank and an effluent tank which are sequentially connected with one another through pipes. The wastewater is treated in the processes such as homogeneous adjustment, biochemical treatment, separation and settlement and the like. Compared with the prior art, the wastewater treatment device has the advantages of simple process, scientific design, high automation degree, good effect and low treatment cost, etc.

Description

technical field [0001] The invention relates to a waste water treatment device, in particular to a waste water treatment device designed for the biochemical treatment of coal chemical waste water and effectively aiming at the characteristics of high ammonia nitrogen and poor biochemical performance. Background technique [0002] The wastewater discharged by coal chemical enterprises is mainly high-concentration gas washing wastewater, which contains a large amount of phenol, cyanide, oil, ammonia nitrogen, etc. [0003] Toxic and harmful substances. CODcr in comprehensive wastewater is generally around 2000mg / L, ammonia nitrogen is 500-1000mg / L, organic pollutants in wastewater include phenols, polycyclic aromatic compounds and heterocyclic compounds containing nitrogen, oxygen and sulfur, etc. Typical industrial wastewater containing refractory organic compounds. The easily degradable organic substances in wastewater are mainly phenolic compounds and benzene compounds; py...
