Embodiment Construction
[0029] Below in conjunction with embodiment, further illustrate the present invention.
[0030] see figure 1 As can be seen, a kind of disc type reverse osmosis of the present invention processes the technique of citric acid waste water, comprises the following steps:
[0031] (1) The waste water is adjusted through the adjustment tank, and then enters the coagulation sedimentation tank after being softened by the chemical agent;
[0032] (2) The waste slag after the coagulation sedimentation tank is processed by the sludge treatment system, and the waste water treated by the coagulation sedimentation tank is transported to the buffer pool;
[0033] (3) The waste water after passing through the buffer pool is sent to the multi-media filter, and then sent to the security filter after passing through the multi-media filter;
[0034] (4) The waste water treated by the security filter is transported to DTRO for treatment, and the treated concentrated water is transported to the ...

The invention discloses a disk tubular reverse osmosis treatment process for citric acid wastewater. The process comprises the following steps: (1) regulating the amount of wastewater by virtue of a regulating tank, softening the wastewater by virtue of a medicament, and introducing the wastewater into a coagulating precipitation tank; (2) treating slag obtained from the coagulating precipitation tank by virtue of a sludge treatment system, and conveying the wastewater treated by the coagulating precipitation tank to a buffer water tank; (3) conveying the wastewater treated by virtue of the buffer water tank to a multi-medium filter, and conveying the wastewater treated by virtue of the multi-medium filter to a security filter; and (4) conveying the wastewater treated by virtue of the security filter to DTRO for treatment, conveying treated concentrated water to a concentrated water tank, and conveying the treated wastewater to a water production tank. According to the process, the citric acid wastewater is subjected to advanced treatment by virtue of a DTRO technique, so that the technical problems that the industrial citric acid wastewater has complex components and is large in water amount, and the standardized discharge is difficult to realize are solved, and the guarantee is provided for the reuse of the citric acid wastewater, the saving of water resources and the lowering of the production cost.
Description
technical field [0001] The invention relates to a waste water treatment process, in particular to a disc tube reverse osmosis process for treating citric acid waste water. Background technique [0002] Citric acid is widely used as a sour agent in videos and beverages because of its pleasant sour taste, refreshing taste, safety and non-toxicity; it can form complexes with divalent or trivalent cations, and is used as a chelating agent and cleaning agent for metal processing. Cleaning agents; and its derivatives are widely used as raw materials in the organic chemical industry. It is an organic acid with a large demand in the world and is widely used in food, chemical industry, construction, leather, agriculture, casting, electronics, textiles, petroleum, Industrial fields such as photography, plastics and ceramics [1]. The main manufacturers of citric acid are currently concentrated in China, the United States, Europe and other countries and regions. my country is the main ...
