Abstract

The invention discloses a sewage zero-discharge treatment device and a sewage zero-discharge treatment method. The device comprises a sewage collection pool, a catalytic oxidation device, a flocculation precipitation pool, a sludge filter pressing device, a sludge crushing device, a drying device, a sewage filtering device, a sewage conveying device and a sludge conveying device, wherein the sewage collection pool is connected to the catalytic oxidation device through the sewage conveying device, the catalytic oxidation device is connected to the flocculation precipitation pool through a pipeline, the sewage outlet in the upper portion of the flocculation precipitation pool is connected to the sewage filtering device, the sludge outlet in the bottom of the flocculation precipitation pool is connected to the sludge filter pressing device through the sludge conveying device, the sewage outlet of the sludge filter pressing device is connected to the sewage collection pool through a pipeline, a sludge cake outlet is connected to the sludge crushing device through a conveying belt, and the sludge crushing device is connected to the drying device. According to the invention, with the method and the device, the sewage assistant process is short, the treated sewage can be recycled as reclaimed water, volume reduction and decrement are achieved after the drying treatment of sludge, resource treatment is achieved after harmless treatment, and pollution hazards are avoided.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a sewage zero discharge treatment device and method. Background technique [0002] Decentralized sewage treatment is a new, economical and environmentally friendly sewage treatment model. The smaller the water volume, the higher the project cost per unit of water volume, and it cannot be effectively connected to the sewage pipe network. For centralized sewage treatment that is not suitable, we should choose and develop decentralized sewage treatment and local treatment according to local conditions. [0003] The main advantages of decentralized sewage treatment: sewage pipelines do not need to cross large rivers, the construction speed of the pipeline network is fast, the construction difficulty is relatively low, there are relatively few lifting pump stations, the investment and operation management costs of the sewage collection system are low; the construction meth...
