preparation example Construction

[0020] The preparation method of above-mentioned sewage treatment agent comprises:

[0021] Step S101: crushing 10 tons of pyroxene andesite porphyrite into a powder of 2 mm or less;

[0022] Wherein, the particle size of the pyroxene andesite porphyrite powder is all feasible below 2 mm, and in order to increase the sewage treatment performance, it is preferable to crush the particle size of the pyroxene andesite porphyrite powder to below 2 mm.

[0023] Step S102: Mix the above-mentioned pyroxene andesite porphyrite powder with 0.5 tons of industrial sodium chloride powder, and stir evenly to obtain a sewage treatment agent product.

[0024] The particle size of above-mentioned sodium chloride powder should be suitable with the particle size of pyroxene andesite porphyrite powder, if the particle size of the sodium chloride powder of purchasing gained is not small enough (or sodium chloride raw material is lump), then need first be pulverized into below 2mm (preferably crus...

Embodiment 1

[0026] In this preferred embodiment, take non-heavy ion industrial sewage (such as papermaking sewage) as an example to illustrate the present invention's method for treating sewage with sewage treatment agent, comprising:

[0027] Step S201: Add 1 ton of sewage treatment agent to the sewage storage tank containing 5000 cubic meters of papermaking sewage;

[0028] Step S202: adding 5 kilograms of polyaluminum chloride to the above mixture;

[0029] Step S203: After stirring the above mixture for 5 minutes, let it stand for 10 minutes;

[0030] Step S204: Drain the clean water in the upper layer, and then remove the sediment in the sewage storage tank.

[0031] In the above process, the Na in the sewage treatment agent + and Ca in sewage 2+ , Mg 2+ For the exchange, the reaction is as follows:

[0032] Na 2 Z+Ca 2+ =CaZ+2Na +

[0033] Na 2 Z+Mg 2+ =MgZ+2Na +

[0034] Among them, Z is pyroxene andesite porphyrite.

[0035] Polyaluminum chloride can be replaced by o...

Embodiment 2

[0039] In this preferred embodiment, the method for treating sewage with a sewage treatment agent of the present invention is illustrated by taking urban domestic sewage as an example, including:

[0040] Step S301: Add 1 ton of sewage treatment agent to the sewage storage tank containing 6000 cubic meters of urban domestic sewage;

[0041] Step S302: stirring the above mixture for 10 minutes;

[0042] In the above process, the Na in the sewage treatment agent + and Ca in municipal sewage 2+ , Mg 2+ For the exchange, the reaction is as follows:

[0043] Na 2 Z+Ca 2+ =CaZ+2Na +

[0044] Na 2 Z+Mg 2+ =MgZ+2Na +

[0045] Among them, Z is pyroxene andesite porphyrite.

[0046] Step S303: Add 5 kg of organic flocculant to the above-mentioned uniformly stirred mixture;

[0047] The function of organic flocculant is to accelerate the sedimentation speed of sludge and CaZ and MgZ.

[0048] Step S304: standing still for 15 minutes;

[0049] Step S305: Drain the clear wat...

Abstract

The invention discloses a sewage treatment agent and a preparation method thereof, and a method for processing sewage by using the sewage treatment agent, wherein the preparation method of the sewage treatment agent comprises the following steps of: crushing pyroxene andesite-prophyrite powder to powder with the fineness being smaller than 2mm; and mixing the crushed pyroxene andesite-prophyrite powder with sodium chloride powder according to ratio of weight parts of 10: 0.5 to 10: 1 and evenly stirring to prepare sewage treatment agent product. In the preparation process of the sewage treatment agent disclosed by the invention, the pyroxene andesite-prophyrite and the sodium chloride are needed to be crushed and evenly mixed only. Compared with the prior art, the invention has the advantages that: the production speed of the product is improved; in the scheme of the invention, every 10t of pyroxene andesite-prophyrite only needs 0.5t to 0.1t sodium chloride, and due to the reduction of use level of the sodium chloride, the raw material cost of the product is reduced to the greater extent and further the production cost of the product and the cost for sewage treatment are reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment agent and a preparation method thereof, and a method for treating sewage with the sewage treatment agent. Background technique [0002] With the implementation and advancement of national energy conservation and emission reduction policies, it is urgent to treat various sewage and wastewater for reuse. At present, sewage treatment mainly includes biological purification method, activated carbon adsorption method, oxidation method, electrolysis method, chemical purification method, etc. Most of the above-mentioned solutions require expensive special equipment, consume a lot of energy, and have high operating costs, especially for small and medium-sized enterprises. heavy burden. [0003] In order to solve the problem of high cost of special equipment, the invention patent with the patent number ZL02104002.8 discloses a sewage treatment agent and a meth...
