Embodiment

[0023] This embodiment is a ceramic processing wastewater treatment system, which has a first treatment zone, a second treatment zone, a sludge concentration treatment zone, and a recovery zone. In this embodiment, the classified collection of 11 types of wastewater is taken as an example. The wastewater is sludge non-recycling production wastewater, high-temperature-polishing production wastewater, low-temperature-polishing production wastewater, matt production wastewater, ceramic tile production wastewater, and corresponding wastewater. Mud does not recycle raw material wastewater, high temperature-polishing raw material wastewater, low temperature-polishing raw material wastewater, matte raw material wastewater, ceramic chip raw material wastewater, waste gas treatment wastewater.

[0024] The first treatment zone includes 5 reaction tanks-1 for treating raw material wastewater, respectively corresponding to collecting sludge without recycling raw material wastewater, high tem...

Abstract

The invention relates to a process and a system for treatment of ceramic processing wastewater, and solves the problems that in the prior art, the treatment of the ceramic processing wastewater adopts centralized treatment, and recovering use has high difficulty. The system comprises a first treatment district, a second treatment district, a sludge concentration treatment district and a recovery district. Through wastewater classification collection and quality-classifying treatment of the system, the treated water can be completely reused, and precipitated sludge produced can be comprehensively utilized, comprehensive utilization of sewage and sludge can be realized and zero emission can be realized.

Description

Technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a ceramic processing wastewater treatment process and system. Background technique [0002] The ceramic processing industry has a large amount of water, tens of thousands of tons per day. At present, centralized treatment and discharge processes are generally used, or simple wastewater treatment and reuse. This not only causes waste of water resources, but also pollutes the environment. The sludge produced is recycled because of its complex composition. Difficult to use. For example, the Chinese utility model patent with application number 201220143815.1 discloses a ceramic handicraft wastewater treatment device, which includes a regulating tank, an acid-base neutralization tank, several reaction tanks, a sedimentation tank, and a clean water tank connected in sequence. The regulating tank in this patent Collecting waste water in one place, which means that all waste wat...
