Problems solved by technology

[0012] Aiming at the problems of high risk, high investment and high cost of the combined waste water zero-discharge process route, the present invention has invented a zero-discharge process route for enterprise production wastewater based on the 3R principle. The process route is guided by the 3R principle. Manage and reduce wastewater discharge to achieve reduction (Reduce); secondly, realize reuse (Reuse) by analyzing water demand; and then make water quality meet the requirements of reuse through simple treatment to achieve recycling (Recycle)

Embodiment 1

[0060] A zero-discharge process route for enterprise production wastewater based on the 3R principle. The schematic diagram of the process route is shown in figure 2 ,Specific steps are as follows:

[0061] Step 1: Wastewater source reduction

[0062] (1) Reduction measures for reverse osmosis concentrated water:

[0063] ①Using reverse osmosis concentrated water to backwash the pretreatment filter in the pretreatment, and reduce the frequency of backwashing to 24 hours / time, reduce the consumption of backwashing water, and save water by 5%;

[0064] ② Under the condition of ensuring the water quality of the produced water, return 10% of the reverse osmosis concentrated water to the water inlet of the reverse osmosis system for circulation treatment, and at the same time, the operating pressure of the reverse osmosis is increased by 10%, the water yield is increased by 10%, and the water is saved by 10%;

[0065] During this process, the reverse osmosis concentrated water d...

[0081] A zero-discharge process route for enterprise production wastewater based on the 3R principle. The schematic diagram of the process route is shown in figure 2 ,Specific steps are as follows:

[0082] Step 1: Wastewater source reduction

[0083] (1) Reduction measures for reverse osmosis concentrated water:

[0084] ①Using reverse osmosis concentrated water to backwash the pretreatment filter in the pretreatment, and reduce the frequency of backwashing to 48 hours / time, reduce the consumption of backwashing water, and save water by 10%;

[0085] ② Under the condition of ensuring the water quality of the produced water, 5% of the reverse osmosis concentrated water is returned to the water inlet of the reverse osmosis system for circulation treatment, and at the same time, the operating pressure of the reverse osmosis is increased by 5%, the water yield is increased by 5%, and the water is saved by 5%;

[0086] ③In the two-stage reverse osmosis-electric desalination ult...

Abstract

The invention discloses a 3R principle-based enterprise production wastewater zero discharge process route, and belongs to the field of water treatment. According to the process route, a 3R principle is taken as a guide; firstly, a wastewater discharge amount is reduced through strengthening management to realize reduction (Reduce); secondly, water demands are analyzed to realize reuse (Reuse); thirdly, water quality is enabled to meet the requirement of reuse through simple treatment, and to realize recycle (Recycle). On the basis of implementing the 3R principle, the wastewater amount is greatly reduced; zero discharge of wastewater is realized by reasonably selecting a low-investment and low-cost zero discharge process. According to the process, water is effectively saved on the premise of not increasing investment and operation cost; the wastewater discharge amount is greatly reduced; the investment and the treatment cost of wastewater treatment and zero discharge process facilities can be effectively reduced; the 3R principle-based enterprise production wastewater zero discharge process route has extremely good economic, social and environment benefits; compared with a simple end treatment and zero discharge mode, the technical economic advantages are very remarkable.

Description

technical field [0001] The invention relates to the field of water treatment, more specifically, a zero-discharge process route for enterprise production wastewater based on the 3R principle and its specific implementation technical scheme. Background technique [0002] In 2010, the National Development and Reform Commission promulgated the "National Water Resources Comprehensive Plan" compiled by the Ministry of Water Resources. Based on a systematic investigation of the current situation of my country's water resources, the plan made an overall plan for the utilization of water resources in the next 20 years, which has become the overall guideline for my country's water resources and water environment industries, and has great significance for water pollution control and water conservation. important guiding significance. The plan stipulates the red line indicator of national water consumption in 2030, that is, the total consumption of national water resources will be less...
