Embodiment 1

[0042] like figure 1 As shown, the industrial inorganic sewage treatment system includes an inorganic filter tank one, an acid-base tank, an oxidation tank, an inorganic sedimentation tank, an inorganic filter tank two and a membrane filter tank connected in sequence. The grid gap size of the inner grid of inorganic filter tank 1 is 5~8cm. The industrial inorganic sewage flows through the grid of inorganic filter tank 1, and after filtering out the particles larger than 5~8cm, the liquid flows to the acid-base tank. Use Ca(OH) in acid-base pools 2 The liquid is made into a saturated solution, and the saturated solution flows to the oxidation tank, where it undergoes the ferrite method, and is 2+ ) / n(M 2+ ) = 15 after removing heavy metal ions, the liquid flows to the inorganic sedimentation tank. When the sewage is in the inorganic sedimentation tank, add an inorganic coagulant with a concentration of 25ppm to the pool. The inorganic coagulant is composed of chitosan with a...

Embodiment 3

[0066] like figure 1 As shown, the industrial inorganic sewage treatment system includes an inorganic filter tank one, an acid-base tank, an oxidation tank, an inorganic sedimentation tank, an inorganic filter tank two and a membrane filter tank connected in sequence. The grid gap size of the inner grid of the inorganic filter tank 1 is 7cm. The industrial inorganic sewage flows through the grid of the inorganic filter tank 1. After filtering out the particles larger than 7cm, the liquid flows to the acid-base tank. Use Ca(OH) in acid-base pools 2 The liquid is made into a saturated solution, and the saturated solution flows to the oxidation tank, where it undergoes the ferrite method, and is 2+ ) / n(M 2+ ) = 15 after removing heavy metal ions, the liquid flows to the inorganic sedimentation tank.

Abstract

The invention discloses an industrial inorganic sewage treatment system and belongs to the field of sewage treatment systems. The industrial inorganic sewage treatment system comprises a first filtering basin, an acid-base pond, an oxidation pond, a settling pond, a second filtering basin, a membrane filtering basin, an anaerobic pond, an aerobic pond, a wet land, a detection pond and an ultraviolet sterilization pond, all of which are connected in sequence. The second filtering basin is provided with a one-way channel leading to the oxidation pond. The aerobic pond is provided with a one-way channel leading to the anaerobic pond. The detection pond is provided with a one-way channel leading to the acid-base pond, a one-way channel leading to the membrane filtering basin, a one-way channel leading to the anaerobic pond and a one-way channel leading to the wet land. The industrial inorganic sewage treatment system has the advantages that arrangement is reasonable and effective, different kinds of sewage is pretreated, and therefore it is ensured that a good and stable treatment effect can still be guaranteed on the condition of emission of different pollutants.

Description

technical field [0001] The invention relates to a sewage treatment system, in particular to an industrial inorganic sewage treatment system. Background technique [0002] In recent years, the economic development speed of my country's cities is relatively fast, and the amount of sewage generated by production and living in cities is also gradually increasing. Compared with foreign developed countries, my country's urban sewage treatment rate is not high, and the process needs to be improved. , the management is still relatively backward, and there is only one sewage treatment plant per 1.5 million people on average, and there are still many problems such as the effective investment utilization rate of sewage treatment plant construction and the low treatment effluent rate. Compared with developed countries, my country's sewage treatment facilities are still very backward. [0003] Most of the pollutants produced by industrial inorganic sewage are heavy metal pollutants. In t...
