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...

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...
