Problems solved by technology

In addition, detergent can emulsify and disperse hydrophobic organic pollutants such as petroleum products and polychlorinated biphenyls entering the water body. A large number of foams in detergent sewage and detergent content reach a certain concentration, which will bring difficulties to wastewater treatment.

Embodiment Construction

[0019] Such as figure 1 A laundry wastewater treatment system is shown, the system includes: 1-reservoir, 2-grid pool, 3-sediment pool, 4-multifunctional treatment pool, 5-disinfection pool, 6-residue pool, 7 -Automatic feeding bin, 8-clean water pool. Wherein, the waste water generated during the process of washing clothes in the laundry is connected to the water inlet of the storage tank 1 through the waste water pipeline, and the water outlet of the water storage tank 1 is connected to the water inlet of the grille pool 2 through the pipeline, and the waste water is filtered out of the clothes in the grille pool 2 Buttons that may fall off on the top, or metal scraps left in pockets, etc., enter the sediment tank 6 through the pipeline, and the outlet of the grid tank 2 is connected to the water inlet of the sediment tank 3 through a pipeline. In the sediment tank 3, the standing time is long For 1 hour, filter and precipitate the soil, fine particles and a little fabric f...

Abstract

The invention discloses a treatment system for laundry waste water. The system includes a water storage pool, a grid pool, a sediment pool, a multifunctional treatment pool, a disinfection pool, a residue pool, an automatic feeding bin, a clear water pool and the like. The multi-functional treatment pool is designed as an inverted trapezoid, the top of the pool is horizontal to the ground, one end of the water inlet is suspended above the ground, and one end of the water outlet is connected to the ground. The angle between the trapezoidal slope and the ground is 30°. Anti-corrosion material, plus a waterproof and heat-insulating layer inside. For the laundry wastewater treated by this system, the treatment effect of COD can reach more than 99.5%, the treatment effect of suspended matter can reach more than 99.9%, the treatment effect of ammonia nitrogen can reach more than 98.3%, and the treatment effect of total phosphorus can reach more than 98.0%. The treatment effect of anionic detergent can reach more than 97.0%, and the treatment effect of Escherichia coli and microorganisms can reach more than 99.8%.

Description

technical field [0001] The invention relates to a laundry wastewater treatment system, which belongs to the wastewater treatment field in environmental protection. Background technique [0002] Analysis of main pollutants in laundry wastewater, pollutants come from detergent. The main active ingredients of detergents are surfactants and builders. In addition, they also contain auxiliary ingredients such as bleaches, fluorescent whitening agents, anti-corrosion agents, foam regulators, and enzymes. Commonly used surfactants in detergents are sodium alkylbenzene sulfonate (ABS) and sodium linear alkylbenzene sulfonate (LAS). ABS is not easy to biodegrade and has a long retention time in the environment. The biodegradability of LAS has been significantly improved, but both have benzene nuclei and cannot be completely decomposed. Both ABS and LAS require phosphate as a builder. Phosphate discharge into water bodies is an important cause of eutrophication. In addition, deterg...
