Embodiment Construction

[0018] The invention provides a flocculant for ecological restoration of black and odorous surface water, which comprises the following components and the parts by weight of each component are:

[0019]

[0020] A kind of production technology of flocculant as described in above-mentioned technical scheme, comprises the following steps:

[0021] Step 1, separately grinding sepiolite, diatomite and bentonite into particles with a particle size less than 0.1 mm;

[0022] Step 2: Mix the sepiolite, diatomite and bentonite treated in step 1 with 1.8-2.4mol / L HCl solution at a ratio of 1kg to 1.25L, and soak at room temperature for at least 2 hours;

[0023] In step 3, the sepiolite, diatomite and bentonite treated in step 2 are washed with deionized water to neutrality respectively, and the surface moisture is removed in an oven respectively;

[0024] Step 4: mix the sepiolite, diatomite and bentonite treated in step 3 with alumina at a mass ratio of 10:3, and then burn at 550...

Abstract

The invention discloses a flocculating agent for ecological remediation of black smelly surface water, belongs to the field of sewage treatment, and solves the technical problems that the existing inorganic flocculating agent is weak in flocculation force and low in precipitation speed. The flocculating agent for the ecological remediation of the black smelly surface water is prepared from the following components in parts by weight: 5 to 20 parts of modified sepiolite powder, 5 to 20 parts of modified diatomite powder, 5 to 20 parts of modified bentonite powder, 5 to 10 parts of magnet powder, 20 to 45 parts of gypsum powder, 10 to 40 parts of alunite powder, 10 to 25 parts of soda ash, and 5 to 20 parts of silicate cement powder. The invention also discloses a production process of the flocculating agent.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and relates to a flocculant and a production process thereof. Background technique [0002] With the rapid development of urbanization, the population density continues to increase, and the industry develops rapidly. Due to the discharge of domestic sewage and industrial wastewater into the river, the water quality of the river is black, and the aquatic plants in the water cannot receive sunlight. The self-purification ability is reduced, and the microorganisms in the water body reproduce in large numbers, resulting in stench, which brings great damage to the environment. [0003] At present, people usually use flocculant to treat this kind of sewage. Flocculant is to condense the filth in sewage into solid drift sediment to purify water quality. It is divided into organic flocculant and inorganic flocculant. Organic flocculants are based on organic polymers, and a large amount of organ...
