Problems solved by technology

[0005] There are many of these small paper mills in various provinces and cities in Northeast China, and almost every city and county has 1-5, but they still cannot meet the needs of the market. It has stimulated a number of related industries and is the pillar of the township first-level industry, but it has also brought a lot of pollution problems. The specific manifestations are: due to the small scale of the enterprise and insufficient funds, it is not conducive to the adoption of advanced environmental protection equipment and technology, so the pollution is relatively serious, and there are no corresponding measures. They adopt a muddling attitude, stand still, and stagnate. They are afraid of cutting them down and dare not invest in construction, which seriously hinders the development of production.

Abstract

The invention relates to a method for treating papermaking sewage, in particular to a method and a tower for quickly precipitating the papermaking sewage. The papermaking sewage of small papermaking enterprises is treated by a two-stage quick precipitation method through synergy of a radial water outlet device, an inclined plate precipitation device, a buffer slot and a spherical filtering filler layer on the quick precipitation tower and process steps of filtering and screening, first-stage precipitation, second-stage precipitation, sewage and slag removal and the like; and the process technology is reasonable, equipment has a simple structure, and the aims of treating papermaking industrial pollution, saving energy and reducing emission can be fulfilled.

Description

technical field [0001] The invention relates to a treatment method for papermaking sewage, in particular to a rapid sedimentation method for papermaking sewage and a sedimentation tower thereof. Background technique [0002] According to the data, the per capita paper consumption in my country is about 25kg, while the per capita paper consumption in developed countries reaches more than 100kg, so the demand for paper shows whether a country is developed and a standard of people's living standards. [0003] Therefore, with the improvement of people's living standards in our country, the demand for paper has increased greatly, and small paper mills have sprung up all over the country. Waste paper has become one of the important sources of pollution in people's lives. Using waste paper to remake paper and turning waste into treasure can greatly reduce environmental pollution, but material conversion is prone to secondary pollution. [0004] According to statistics, the paper a...
