请帮我用英语翻译一下问题补充里的这段话啊，不要在线翻译来的，毕业论文啊各位给力啊！

Question

我国印染企业每天排放废水约为300-400万吨。这些废水成分复杂、色度大、浓度高且生物难降物质多，特别是近年来，合成纤维的品种和数量的增加以及化学浆料(PVA)代替淀粉在印染工业中的应用，使得印染废水更加难处理。染料废水的处理方法很多,主要有氧化、吸附、膜分离、絮凝、生物降解等。单一生化处理工艺难以达到排放要求，本文介绍了高分子凝聚法、厌氧—好氧—生物炭接触氧化法、硅藻精土法等印染废水综合处理技术，这些技术具有处理效果好、出水水质稳定、设备简单、操作管理方便、能耗低等特点而且有较好的经济效益，达到了以废治废的目的。处理后水质达到城市截污管网标准要求，是较为理想的印染废水处理工艺。

Answer 1

China dyeing companies daily wastewater is about 300-400 tons. These wastewater complicated composition, chroma, high concentration and biological material, especially difficult to drop in recent years, synthetic fiber and the variety of the increase in the number of and chemical pulp (PVA) instead of starch in dyeing industry application, make printing and dyeing wastewater treatment more difficult. Dye wastewater treatment method is very much, basically have oxidation, adsorption, membrane separation, flocculation, biodegradable, etc. Single biochemical process cannot achieve emissions request, this article introduces the polymer condensed method, anaerobic -- aerobic - biological contact oxidation method, diatoms charcoal pure thickly etc printing and dyeing wastewater comprehensive treatment technology, and these technologies have better treatment effect, stable discharging water, the equipment is simple, convenient operation and management, energy consumption and has characteristics such as good economic benefits, achieve the purpose of using waste treat waste. After the treatment of water quality reach urban cut pollution pipe standards, is the ideal printing and dyeing wastewater treatment processes.

Answer 2

Printing and dyeing enterprises in China is about 300-400 tons of waste water per day. The water complex composition, color large, difficult to reduce high concentrations of biological substances and more especially in recent years, synthetic fibers and increase in the number of varieties and chemical pulp (PVA) instead of starch in the application of printing and dyeing industry, making printing and dyeing wastewater more difficult to solve. A lot of dye wastewater treatment, mainly oxidation, adsorption, membrane separation, flocculation, bio-degradation. A single biochemical process difficult to meet emissions requirements, this paper polymer coagulation, anaerobic - aerobic - biological contact oxidation of carbon, such as printing and dyeing wastewater Diatomite integrated treatment of indigenous technologies that have a good effect, water quality stable, simple equipment, easy operation and management, and low power consumption and a better economic efficiency, in order to achieve the purpose of waste by waste. Treated water to the city sewage interception pipeline network standards, is an ideal printing and dyeing wastewater treatment process.

Answer 3

In China printing and dyeing enterprises is about 300-400 tons of waste water per day. The water complex composition, color large, difficult to reduce high concentrations of biological substances and more especially in recent years, synthetic fibers and increase in the number of varieties and chemical pulp (PVA) instead of starch in the application of printing and dyeing industry, making printing and dyeing wastewater more difficult to solve. A lot of dye wastewater treatment, mainly oxidation, adsorption, membrane separation, flocculation, bio-degradation. A single biochemical process difficult to meet emissions requirements, this article describes polymer coagulation, anaerobic - aerobic - biological contact oxidation of carbon, such as printing and dyeing wastewater Diatomite integrated treatment of indigenous technologies that have a good effect, water quality stable, simple equipment, easy operation and management, lower energy consumption, but also good economic, reached the purposes of use waste to treat waste. Treated water reached city sewage interception pipeline network standards, is an ideal printing and dyeing wastewater treatment process.
