Abstract

The invention discloses a cotton pulp wastewater treatment integration technology. Cotton pulp wastewater subjected to biochemical treatment is placed in a catalytic oxidation tower, and meanwhile an oxidizing agent is pumped into the catalytic oxidation tower through an oxidizing agent adding box; a catalyst is arranged at the inner bottom of the catalyst oxidation tower; air is blown in through an air blower while the wastewater enters the tower; the sewage treated by the catalytic oxidation tower enters a contact pond, and an efficient air diffusion system is arranged in the contact pond; water flowing out of the contact pond enters a flocculation and sedimentation pond; a flocculating agent is pumped into a flocculation pond body of the flocculation and sedimentation pond through a flocculating agent adding box, meanwhile a coagulant aid is pumped into the flocculation pond body of the flocculation and sedimentation pond through a coagulant aid adding box, a stirrer and a water pump in the flocculation pond body of the flocculation and sedimentation pond are linked, and water flowing out of the flocculation and sedimentation pond can meet standards and be discharged. The COD and the chromaticity removal rate are high, the operation process is stable and reliable, operation is easy, the treated sewage can be reused, and economic benefits are considerable.

Description

technical field

[0001] The invention relates to the technical field of sewage treatment, in particular to an integrated process for the treatment of cotton pulp wastewater. Background technique

[0002] Cotton pulp is one of the important raw materials for the chemical fiber industry. With the rapid development of social economy, the chemical fiber industry has higher and higher requirements on the quality of cotton pulp raw materials, and the demand is also increasing. However, the cotton pulp project is a large water consumer and polluter, and black liquor is the most important pollutant produced in the production process of cotton pulp. Therefore, whether the black liquor can be effectively treated is the main environmental protection issue of the project, and it is also the current issue of the cotton pulp project. key constraints to development. Cotton pulp production has a large amount of wastewater and a high pollution load. The black liquor produced in the cotton p...

Embodiment Construction

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0015] In the embodiment of the present invention, an integrated process for the treatment of cotton pulp wastewater consists of the following steps:

[0016] a. After the biochemical treatment, the cotton pulp waste water is lifted by the water inlet pipe 15 through the water pump 1, and then enters the water distribution system 3 in the catalytic oxidation tower 5 through the lifting sewage pipe 16, thereby entering the catalytic oxidation tower 5 tower, on the water inlet p...
